I'm running a random-vibration analysis of a power supply with the following:
Nodes = 37 K, Elements = 17 K, and DOF = 158 K.
The model meshes correctly, but it takes days to solve. I'm running on a Quad Core with 3 MB of RAM. Any ideas on how to reduce the solution time? I've been told that I can't use contact sets when running random vibration. Could anyone confirm this, and if so, are there work arounds. The model is a mixture of solids and sheet metal parts. I've completely simplied the model so there are no small features.
