Very quick result Least training required

Accuracy can be increased. Export option can be further enhanced

I use SIMSOLID to simulate various mechanisms. I do linear, non-linear and modal analysis but the software has over capacities (dynamics and thermal). The mechanisms I work on are complex with a lot of contact between the parts. I can obtain results after few clicks and few minutes, this allows me to test a maximum of solutions in a very short time.

Possibility to import natif CAD format. Type of analyzes that can be performed: linear, non-linear (geometry, materials, contact), modal, dynamic and thermal. It is possible to automatically create weld beads , to detect contacts and to detect scews/bolts. The software is always update with new features. The support can easily be reached

You can't modify for the moment the CAD in SIMSOLID interface. The import of CAD is a little bit long

It can take the full CAD, right down to the nuts and bolts, and use it add more detail to the analysis. It has a great range of features from linear static to modal and more. I like the the feature where simulations setups can be copied over to new version of the design automatically

It seems simple but there are some key settings you have to get right in order to get sensible results. Sometimes habdling the number of contacts and joints in an assembly is unwieldy.

Easy to use geometrically model without mesh. Easy to use local 9n laptop for complex models.

Should be added something related by explicit analysis, but I guess Is not easy. And perhaps in future something related by an interface with a deep learning model.

I like the non-linear analysis that SimSolid allows.

There is no easy way to transition from Solidworks Simulation. Seeing what materials are applied takes too many clicks.

Only positiv experience of SimSolid. Easy to use and to learn. As you have to import all geometry, it is a good feature that SimSolid can recognice if it is a simular geometry, BC and other features applies directly and you get many different results in the tree to caompare.

Easy to use, you do not have to mesh the model something that take a lot of time. Wery fast solver, 5 time faster then traditional FE softare. Easy to learn, many features and is still under development.

Maybe to easy to use. Have seen som strange results that I can not explain.

I like the simplicity of the software interface and ease of use. It can import and run simulations on breb models as well as mesh files. The software successfully runs simulations on intricate geometry without the worry of mesh generation failure.

Not many customization options are available in the simulation setup. It is highly memory intensive but uses less CPU which makes it slow in operation. I am facing inconsistency in the results sometimes.

It belongs to HyperWorks products.It's easy to get an education, and the price isn't bad.

It is different from the program you are used to.

The most impactful feature is the running time of the simulation. Compared to Altair Optisctruct, simsolid has a gain in pre-processing and post processing as well. I think this tool works greatly as a pre dimensioning software. For a more detailed use, further research is needed.

The behavior of polymeric materials and composite is not quite understood yet. So, develop better caracterization for these materials

Full capabilities like friction contacts and large deformations are required so we can evaluate it.

The simple procedure for pre-processing of the simulation model.

It cannot simulate friction contacts and large deformation in explicit simulation like in Radioss.

This comment is NOT about SimSolid, but about the survey. It's too constricted in how questions are to be answered, when drop-down choices don't include what I want to say. Saw this earlier on page 1 and 2.

1) ZERO need to spend time to mesh a model 2) ZERO need to spend time to first simplify a model, and remove small details, features, etc. 3) Ability to import a huge number of neutral file formats, as well as NATIVE CAD file formats 4) Ability to run a simulation in seconds to minutes. That REALLY happens! 5) Small footprint of disk space used, once installed. Surprisingly compact. 6) Ability to handle increasingly more complex types of simulations, as it has evolved over time

1) It will be nice if/when the GUI that is as it was designed (before the acquisition by Altair), can be more similar or eventually the same, as the GUI used with Inspire 2) The Tutorials are very good, but there can never be enough. More examples, videos, tutorials would be welcome.

Simply put: I was astonished by this program. I used it for my bachelor thesis and it really saved me months of time.

The thing I really liked about this product has been the simplicity of use. I mostly used it for displacement and stress analysis on complete assemblies. The process was ridiculously fast: I would model my assembly in Solidworks and directly from there (SimSolid does have some nice integrations) I would click an icon that would place my assembly in the SimSolid environment. From there it was possible to define different load configurations directly on the assembly (that's something I had never seen) and see the results in just a bunch of seconds (maybe 4 seconds?). When the results are out you are able to see stresses, displacements, modal analysis (these are the features I looked at)... and you can navigate between results from different load configurations in 1 click. You can then save scenes of your work, hiding parts that are not useful for certain focuses (you might want to see stresses applied to a piece that is hidden by other pieces in the assembly) and get back to analyse it later...

As I have used just a bunch of simulation programs for the moment, I didn't notice downsides of the program during the use. The simple stuff is really good and intuitive but there might be some problems with advanced feature... I really can't say that I've seen them though.

SimSolid has a very fast and straight forward setup process which helps a lot to get a first impression of a systems behavior. The results are good enough for rough estimations and visualizations especially when you are looking at something "new". A real benefit is also the fast and reliable auto contact definition algorithm. Even models with several hundred parts can be set up within 1 hour.

The results can be very inaccurate depending on the problem. And to very the error can be very difficult because to do convergence study you have to run the model from the beginning every time. So solver and solution control are definitely a weak spot and can be further improved. Also the model discretization for results visualization sometimes looks very rough and there is no control for that (created a ticket already).

For linear static SIMSOLID is the best option for solving- single part as well whole assembly simulation of the parts.User friendlieness, solving speed is very high.Results accuracey very good in simple linear static analysisTransient,nonlinear analysis yet to be validated

Ease of learn,use and take out the resultsFastner Pretension resultsStructure as whole assembly simulation

Results accuracey sometimes need to be verifiedModel corrections not possibleUndo option is not availableMeasure,move,replace parts in Assembly is not possible

We are rolling out to more and more designers so that inital concept screening is done by designers and Professional CAE analyst can focus on final and complex verifications

ease of useshort learning curvecan use without/little hand holdingSpeedease to switch to non linear fea

more options to control each DOF and not to depend on limited options.

Great! so far.

I am very impressed with SimSolid, I have used a lot and I recommend my clients also for preliminary check.although it cant replace the FEA results, but it gives a nice understanding about the product which has large number of parts and its material library is very useful.

GUI should be changed to "Altair New generation GUI" it will dominate easily once this is done.

FEA analysis software at a great price. Runs quickly, accurately, all from an stl export. Navigation through the software is almost self explanatory, but tutorials are available if anything is unclear. Components or assemblies are easily constrained and loaded, and graphical results can be quickly added to your Powerpoint presentation.

Easy start up and intuitive menus. I switched from Siemens NX Nastran without any issue adopting it. Working with .stl files instead of a mesh is very easy. At first I wasn't sure of the accuracy, but I benchmarked it against hand calculations and Siemens NX Nastran and I was impressed. Solve time on both components and full assemblies is quick. The software is also very intuitive with assemblies, stitching where required or adding bolt connections. If there were any issues, the owner would email you directly with quick solutions. Looking forward to it's app in Onshape, as long as the cost is not too high.

License is a pain. It should be floating because we don't always use it on the same machine. More literature should be available about how the stl is an accurate mesh. People don't believe my results until empirical testing proves the software is accurate.

Overall I have a positive experience with SimSolid. We have implemented it into the early stages of our design processes.

The ability to perform early stage analysis on different product designs in terms of speed is second to none.

Legend editing is somewhat lacking. Also ability to integrate 1D elements (springs, rigid and unstructured mass) would be great.

Overall experince is very positiv, because the use of SimSolid save us a lot of time and is easy to use. As well for employees with low experience.

Fast modeling and shoirt computing times of structures with high quailty results

In concept development, a structure is usually not fully constructed. Missing components and functions cannot be modeled in SimSolid. Definitions for various joints are missing.Model tree cannot be organized and could be clearer (especially with large Modells)

Ease of operation. Undo redo command useful one.

I didn't find such a things which annoyed me during the use of sim solid

Complex parts static analysis in short time period.

We can do large and complex parts assembles with simsolid which very good. With in seconds we can make static analysis.

You have to run the model from the beginning every time when you are doing convergence study.

Ease of use and fast iteration of designs

Opaque mathematical models. Difficult to understand how calculation parameters affect the results

Through the use of the external approximations theory Altair have managed to build an amazing, robust and very fast simulation engine. It supports meshless simulation and it can handle local contact imperfections so well that it can be considered one of the most reliable simulation softwares on the market.

Nothing in general, perhaps GUI can be polished a little bit.

Innovative computationGood for early stage design processIncludes AI and ML to analyse the design geometry

It sometimes feels its hard to ascertain how the mathematical calculation variables are affecting the final result.

Experience was great.

Very easy to use. I was able to setup the model within minutes and also solve the model within a few minutes. I compared the results with Ansys. I got the same results.

None. I did not find any problems with the software.
