Take Advantage of Repeatedly Used Components in CAD by Instance Meshing in ANSYS Mechanical

Repetitive meshing tasks can be a significant portion of the time a user spends setting up an FEA model for simulation. In cases where components are reused multiple times in an assembly, the meshing can be tedious.

Select 20 of the exact same face in a bolt circle to specify the number of elements on an annulus…

Select the 20 bodies that those 20 faces belong to for a mesh method…

What if the number of bodies/faces/even edges is larger? Continue reading

The Impossible is Now Routine

Sometimes, during the course of doing what you might have thought was a routine simulation, you realize that you are doing something that didn’t used to be routine.  In fact, it may have been impossible without advances in software and hardware in recent years.

Recently, DRD was conducting stress simulation for a casting assembly from Davis Tool & Die of Fenton, MO. As the geometry was meshed and examined, small details of the casting continued to become evident and additional refinement was needed.  As seen in the images below, the model became quite large. Continue reading
