Altair SimSolid Reviews & Product Details - Page 2

I am thoroughly impressed with SimSolid's speed and low processing power consumption, even when solving complex problems. The interface is well-organized, providing a clear workflow that is easy to follow. Additionally, the software is easy to install and quickly ready for use, making it a highly efficient tool when combined with its rapid processing capabilities. The availability of online training for new users is also a significant advantage, as it greatly aids in onboarding within the company. Review collected by and hosted on G2.com.

So far, I have not identified any negative aspects to mention about SimSolid. Review collected by and hosted on G2.com.

Quick and easy to use, you can generate a quick model in just minutes and the solution time is fast, no need to mesh Review collected by and hosted on G2.com.

There is not intutive or guidelines for some of the modeling elements it use, sometimes the restrictions are difficult to set if the constraints elements do not have a clear definition or how they are being used Review collected by and hosted on G2.com.

I have been using SIMSOLID for over two years, and its advanced meshless modeling capabilities have proven invaluable in expediting the analysis of complex geometries. This software has significantly enhanced my ability to provide rapid results to my CAE team, enabling them to make timely decisions and implement appropriate design modifications.

SIMSOLID has been particularly beneficial during the conceptual design phase of several projects, including the design of lifting devices, steel structures, rail structures, heavy mining equipment, and various general mechanical systems. The efficiency of the software has allowed me to assess the reliability of multiple design iterations quickly and effectively, thus saving considerable time during the early stages of development. Once a mature design is reached, I conduct further validation using more detailed finite element analysis (FEA) tools, such as HyperMesh, to obtain more precise stress values.

The ability to extract reaction forces, apply contact interactions swiftly, assign various joint properties, and conduct a range of analyses—from linear static to fatigue and complex vibration analysis—are some of the key features that make SIMSOLID highly efficient for preliminary evaluations. This versatility has been instrumental in providing swift insights into design iterations and offering informed recommendations.

In summary, SIMSOLID has been a crucial tool for my team during the conceptual phase of design, allowing for the timely selection of appropriate design modifications and significantly reducing the time required to achieve a mature model. Once the design has reached this stage, detailed FEA software is employed for final validation. Review collected by and hosted on G2.com.

While SIMSOLID offers significant advantages in rapid conceptual analysis, there are a few areas where it falls short. First, the accuracy of stress values can sometimes be a concern, especially when compared to more detailed finite element analysis tools. While it serves well in the early stages of design, the stress results often require further validation through more robust FEA software to ensure precision.

Additionally, the running time can be significantly impacted when dealing with multiple contact interactions, which detracts from the software's otherwise efficient performance. This issue becomes particularly noticeable in complex assemblies where multiple joints or contacts are involved, leading to longer computation times.

Finally, the lack of geometry editing features within the software is a limitation. Users must often rely on external CAD tools for modifications, which can interrupt the workflow and lead to inefficiencies. Review collected by and hosted on G2.com.

Altair SimSolid is an unparalleled tool, allowing you to evaluate design concepts in seconds until you find the one that performs best and meets the specific requirements of each project. The learning curve of Altair is very fast, with short, intuitive, and sufficient training sessions to get you started working on your own projects.

There are two aspects of Altair SimSolid that I find most noteworthy: (1) Automation of preprocessing, and (2) the evaluation of new models. (1) Reading complex assemblies is very fast, and the software is extremely capable of correctly recognizing contacts, welds, and even bolts/nuts, without requiring CAD simplification. (2) Once a simulation model is created, it is very simple to duplicate it and apply it to a new geometry without making major adjustments.

I use Altair SimSolid in my projects because it allows me to evaluate the performance of complete assemblies at a very low computational cost, speeding up my design processes. Finally, it is worth noting its compatibility with other Altair products, enabling the verification of models with traditional finite elements (with mesh), complementing the analysis with topology optimization, or even evaluating multiphysics with EDEM.

It's not a problem specific to Altair, but once you've experienced simulating without a mesh and getting results in such a short time, you feel that it would be great to have an equivalent tool for other physics, such as CFD (Computational Fluid Dynamics). Review collected by and hosted on G2.com.

Great for imperfect geometry. Great control over contacts. Fast solving. Review collected by and hosted on G2.com.

Hard to understand how to optimize solves for accuracy - unclear UI. Documentation on advanced features is unclear, there are several features I have not been able to work out how to use. Review collected by and hosted on G2.com.

The most helpful feature about simsolid is its quickness in pre-processing a model. When in need of a quick simulation for verfifying things, Simsolid is the best because you can quickly generate the model. Review collected by and hosted on G2.com.

There are few downsides related to it. If I were to find some disadvantage, I would say it is the hard time you will have when trying to track down the incertanties inside the model. But honestly, if you got to this point you should just use Hypermesh... Review collected by and hosted on G2.com.

There are two major advantages. First, you can bring in large assemblies like an dozer or excavator frame and it will easlily connect or determine the contact between items that are not contacting or that are interfering. This allows one to bring in files or components that are designed for manufacturing like large weldments without having to alter them first to have exactly face to face contact. The other is that after bringing in the large assembly, you do not have to mesh it to be able to do contact analysis. Also, even with contact, the analysis runs extremely quickly for the complexity of the model Review collected by and hosted on G2.com.

It would be nice to be able to have more options for loading for points and lines especially prescribed displacement. Review collected by and hosted on G2.com.

Simple to use. Mesh free solution. Ease of use. Review collected by and hosted on G2.com.

Results don't match with ANSYS. Assembly level simulation with contacts, its a challenge Review collected by and hosted on G2.com.

It gave me the ability to create simulations managing very large assemblies (several hundred components) in a short time with very good accuracy of results. This has speeded up the design workflow without losing quality. Review collected by and hosted on G2.com.

The possibility of modifying the geometry of components (even if only small changes or component displacement) would make the instrument truly perfect Review collected by and hosted on G2.com.

SimSolid is meshless, sensible, and easy-to-use software. The calculations are very fast. Review collected by and hosted on G2.com.

No mesh, so accuracy is coarse for small shapes. Review collected by and hosted on G2.com.
