Large model analysis using Altair SimSolid

Using Altair SimSolid, it is possible to analyze large models with many thousands of parts. Our unique technology makes this practical on a desktop or even laptop computer. In dealing with large models, users need specialized user interface tools to handle the … Read More

Applying loads and displacements

Altair SimSolid provides very general methods for applying loads and displacements. They may be applied to any part region and in any arbitrary reference frame. All this is done from one convenient Load/displacement dialog. Read on to find out more.

Altair SimSolid virtual connectors

In Altair SimSolid, virtual connectors can be applied in cases where the corresponding connecting parts are missing in the model. Virtual connectors are a rigid imaginary part created between selected faces representing the geometrical support of the connector. The type … Read More

Partner blog post – Cranking Away with Meshless FEA

Fastway Engineering just did an excellent blog post on designing for dynamics. It compares how mode shapes are created with Altair SimSolid and traditional FEA. To read all about it follow this link: http://www.fastwayengineering.com/cranking-away-meshless-fea/  

How to use the Altair SimSolid check rigid motions tool

Sometimes, rigid motion mechanisms, that is movement between parts, can be difficult to detect and visualize in large complex assemblies. Altair SimSolid now provides a new tool that makes this easy.  See the video below to learn how.  

Altair SimSolid technology overview

Here is a video that goes over the technology behind Altair SimSolid and how it is different from traditional FEA. It includes lots of detail on the Solution settings dialog and how to used it in different situations. Take a … Read More

Onshape CAD integration improvements

Onshape is a popular full-cloud 3D CAD system. All editions of Altair SimSolid come with full access to Onshape and now the user experience has been further refined to make browsing on-the-cloud documents easier and faster. Read on to find out more.

Using inertia relief in Altair SimSolid

Inertia relief can be used to analyze a structure that is not constrained and can move as a rigid body. Typically applications are models of structures such as airplanes, rockets or satellites that are not connected to ground. Other applications … Read More
