Depends on the problem you are working on. You may use frequency domain or time domain analysis. Or you may use both by using wavelet transforms. http://www.novosim.com Product Development Services (cad/cae/test) Medical Device R&D

The reading (raw) data must be the same for both systems if you have same initial settings (resolution etc.). Post processing capabilities may differ depending on the capabilities of the systems. http://www.novosim.com Product Development Services (cad/cae/test) Medical Device R&D

Hi, I would model both to account for stiffness and mass introduced by the test item to the fixture. If you don't have a fixture at hand, it will be faster to optimize for min. freq (max. sweep frequency) from a design space with test item FE attached. I think if you assume a point mass for the...

I think a CAE analysis will give good insight beforehand to estimate the nodal points before starting modal testing to determine acc. and excitation locations. http://www.novosim.com Product Development Services (cad/cae/test) Medical Device R&D

Hi, I would not go with auto meshing if this is a full vehicle. Actually I never recomment auto mesh unless you have a very good CAD at hand. Some geometries may not be perfect and your mesh will end up with missing parts, interfering parts etc. You can generate a weld file or a connector file...

Hi, Initially, in your EIGRL command, you entered up to 20 modes as I see, it may not cover 50 Hz (on the laptop I am writing I do not have a pre-processor or my nastran books). Later I can update the post. FREQ command looks a little fishy, I will check that one also. I am not clear why you...

Hi, Nodal points will change for every frequency at which you are exciting the beam (different mode shapes). However, I would like to know how do you know beforehand where the nodal point will be with a hammer hit for different frequencies? I think a shaker will be more useful. Thanks Mert...
