How can we define friction at 1D-joints using Optistruct solver?

08 September 2022 0 3K Report

I have a question regarding the Optistruct solver. In the case of a 1D joint approach, I would like to define the static and dynamic coefficients of friction at all joints of the mechanism. Would it be possible to accomplish this? I contacted Altair several years ago but they advised that surface friction could be applied by a 3D joint approach, but this would take too much time to solve since I have multiple revolute joints. Therefore, I would like to use a 1D joint approach, but how do I define friction at each 1D joint?
