I suspect you need to plot the magnitude as opposed to the real component. But I don't understand what is meant by "receptance" The options are real, imaginary, phase and magnitude and at phase angle. These are in result options under the complex form tab. You control the phase resolution by...

for stress in MPa that works - so it is something in the order of 7e-9. It must be something else. Bill McEachern, P.Eng. Redstone Six Consulting Ltd. www.redstone6.com

It seems like just doing 50g static load would do the trick. If you did a test how would you do it? I can't see doing a "drop" test to get a controlled 50 g load. I would advise if a pulse of 50g is prescribed then it would best be handled as a dynamic study. It could NL or linear depending on...

I use both Abaqus and Swx sim. You can get a decent approximation with Swx sim in my humble opinion. You need to get rid of the plates in the sim and just use restraints for the top and bottom - fixed should be fine but it depends on what elements are and what the geometry is. The lid contact...

I would advise just getting through the course with a decent grade. You could probably do a PhD on this. I would suggest you outline the challenge of the whole problem and the tackle some appropriate aspect of the problem and skip the really tricky bits. Like figure out the energy storage in the...

If I understand what your after correctly...which I may not..you want identify if the high stress at a location is critical or not? By critical I mean it can lead to failure or it just bleeds out on local yielding. If this is right then I would advise you run the problems with a perfect...

I have seen that deformation wave speed error show up when density was incorrectly specified due the consistent units requirement when imperial/US customary units where used - density was not in slinches it was in lbm/in^3. Bill McEachern, P.Eng. Redstone Six Consulting Ltd. www.redstone6.com

I am familiar with the virtual topology tools. The tet mesh I have works but the controls available to tune the mesh are lacking or it could be my lack of understanding. The lack of a growth ratio control is what I view as the biggest short coming. Bill McEachern, P.Eng. Redstone Six Consulting...

Well, I have answered my own post. In the database options under the complex tab you can select the magnitude, phase angle, real, imaginary or phase angle value. Not exactly obvious. Simulia could do with a CAE interface redo. Not to mention bring the tet meshing a bit more upto date. The SWX...

Hi, My first post to this forum so forgive me if my understanding of the protocol is amiss. I have run an SSD analysis (harmonic in other codes). It has 4 steps:modes extraction followed by a 1g base motion excitation in X, Y, & Z. Essentially is is a rectangular flat plate with 6 beams oriented...
