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

New Altair SimSolid design studies

The primary goal of design-analysis is to evaluate the effect of design changes on the product’s performance. This needs to be done quickly and completely – at the “speed of design”. Most embedded CAD system analysis today are limited to … Read More

Creating spot welds in Altair SimSolid

Spot welding is a common manufacturing technique to connect sheet metal parts in an assembly.  While the process to create the physical weld is well understood, the methodology to model it for analysis is not. Traditional FEA systems require a … Read More

Controlling Altair SimSolid solution accuracy

Using Altair SimSolid, it is very easy to setup and run a structural simulation. Geometry simplification and editing is not required and there is no laborious, error prone, meshing steps to worry about. Although Altair SimSolid does not have a … Read More

How to create a bolt load in Altair SimSolid

In traditional FEA, there are many approaches to simulate bolt loading. Most of them are based on the idea of bolt shank shrinkage. The shrinkage creates the force applied to parts which are connected to the bolt.  The bolt itself usually … Read More

Managing materials in complex assemblies

Applying material properties in Altair SimSolid is very straightforward. Open the material application dialog, select a material property, select one or more parts in the Project tree or the Graphics window and pick “Apply to selected materials” – simple. But what if … Read More
