Is it possible to extract the stiffness matrix from COSMOSWorks?I am evaluating the software for possible use at our company, andthis functionality is critical for us. It is easily done in otherFEA packages, but seems to be a bit tricky in COSMOSWorks. Any ideas?
Thanks,
NateHi Vince, thanks for the reply. Any format would be acceptablereally. As long as we are able to correlate stiffness valueswith nodal positions we can manipulate the data externally to suitour needs. Stiffness (or actually, compliance) data would findimmediate use in our dynamic modeling, as well as some possibleelastohydrodynamic lubrication studies in the future.

OK, this is a very old thread, but I have the same requirement to calculate the stiffness matrix for various locations, particularly the radial stiffness (N/micron) and bending stiffness (Nm/degree) of cylindrical bores, for transfer to separate gear, shaft & bearing analysis software.
I know this is possible in other FEA packages, but can't find any real references to it for SW/Cosmos, so if anyone has any ideas, please let me know.
At the moment I have to go through the process of applying a series of single forces & single moments and measuring the deflections, which is very tedious for a large model!
Thanks, John.
