Hello everyone, I'm studying the forced response of a simple structure. To do this, I've defined a temporal excitation and I'm using a viscoelastic memory material (MATVE). By extracting the natural frequencies and comparing with a Matlab calculation, I obtain the same values. Unfortunately, the...
Hello, I'm a mechanical student.
I'm doing a cyclic symmetry analysis using NX NASTRAN. When I compare the eigenvector between the fan sector and the complete structure, I get an error. My model is not convergent.
But I'm working on hexahedral elements and when I increase or decrease my...
