can I export Abaqus stiffness matrix mtx from Solidworks simulation?
I'd like to use it in KISSsys for casing gearbox calculation
I believe you can only export an "inp" file for Abaqus from Solidworks. There will be some warnings of what doesn't get included (i.e. remote loads) that will have to be set up in Abaqus.
Maybe one of the DSS experts could answer better. Have you checked with your VAR?
Please see S-052697 in the SOLIDWORKS Knowledge Base (KB) for a potential approach suitable for advanced users. However, please note that you must have SOLIDWORKS Simulation Premium to use the procedure described in the KB, and the format of the resulting file will not be .mtx.
