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

New Altair SimSolid safety factor plots

Safety factors are used to characterize zones of possible material failure and are based on material specific failure criteria. Now available in the latest release of the Altair SimSolid Standard and Power editions, safety factors contour plots can be displayed for … Read More

New Altair SimSolid hydrostatic pressure load

Hydrostatic pressure is defined as the pressure exerted by a fluid at equilibrium due to the force of gravity. Hydrostatic pressure increases in proportion to depth measured from the surface because of the increasing weight of fluid exerting downward force … Read More

How Altair SimSolid processes units

In Altair SimSolid, all model geometry is stored in the units defined by the CAD system or, in the case of STL, the units defined when reading the file. For consistency, all measurements or other references to the geometry will … Read More

New bearing load and hinge constraint

With the latest release, we have added new boundary conditions that allow the creation of hinge constraints and bearing loads. The hinge constraint will allow free rotation about the center line of a cylindrical face but constrain movement in both the radial … Read More
