Hi , everyone! I've trouble with modal reduction due to some issues with solver. It refuses to work if multiple nodes are linked with ChLinkPointFrame (falling out with exception). It seems that such a choice of constrains leads to highly degenerate set of equations that the eigen solver can't handle (have no time for deep debug). I'm looking for a walk around and the only reasonable solution I can see is to add ChNodeFEAxyzrot connected to existing nodes with some Element (but which one?????). The model is imported from TetGenFile so all the nodes are ChNodeFEAxyz. It's not quite clear how attach ChNodeFEAxyzrot to ChNodeFEAxyz with some Element.
I hope that this is trivial and I'm just stupid enough to oversee the solution. Any advice is appreciated) ___________________ Best regards, Victor -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
