New Altair SimSolid inertial loads

A inertia load is a body load uniformly distributed over the volumes of the parts in an assembly. In Altair SimSolid, both translational and rotational inertia loads are available. For any given analysis, one translational inertia load and multiple rotational inertia … Read More

Visualizing load paths

OUTLINE Review what safety factors are. Analyze model A Visualize load paths using Safety Zones Use this SZ information to modify geometry in SOLIDWORKS Analyze model B Visualize load paths using Safety Zones again.

Altair SimSolid Modal Participation Factors

Every structure has the tendency to vibrate at a given set of natural frequencies. Each natural frequency is associated with a shape, called a mode shape, that the model tends to assume when vibrating at that frequency. The modal participation factor … Read More

Apples to Apples, not Apples to Oranges

Many people that try Altair SimSolid for the first time want to understand how it compares to well know reference solutions. A common comparison are beam models.  There are many references available and the theoretical values are easy to hand … Read More

Altair SimSolid, a revolution in design simulation

Everyone that tries Altair SimSolid for the first time invariably does it using the same methods learned from years of doing classical FEA.  They isolate a small group of parts, simplify the geometry, guess at some boundary loads/constraints and run … Read More
