NX Nastran Friction Question.

NX Nastran Friction Question.

NX Nastran Friction Question.

(OP)
Dear All,

Can someone please explain to me in more detail the FRICMOD option in NX Nastran. I have been using various options with no success. Of course the model runs great with a constant static friction Fricmod=1 and fpara1=.2.

I want to introduce a static and dynamic friction so I naturally used Fricmod=2 and entered values for fpara1&2. The model then acts really strange. In reading the manual I think it says use fricmod=4 if you want a static and dynamic friction. However, it wants three values now instead of two.

If anyone has experience using these parameters I would greatly appreciate more clarification.

Sincerely,

TheCADGUY
