Hey,
I am working on the Multi body dynamics of a 300kW VAWT as part of my graduation thesis. I have created a reduced order model of the turbine using SIMPACK (MBD solver from dassault systems). I am facing some difficulties with running modal analysis due to error in modal matrix being singular.
I am reaching out to people who have worked with SIMPACK, hoping to get some help with my model .
How did you create the elastic components?
You might have some errors in: dynamic reduction of FE-Model and export to SIMPACK. Check for each elastic component seperately, if the modal Analysis in SIMPACK is possible...
I think Anays Rigid Dynamics will give you all the possible options in comparison to any other tool. Try for it to cross verify the results.
