Dear nx nastran users
I have 2 questions..
I would like to know how to model the viscoelastic that changes the Young's modulus and loss factor
depending on the frequency.
In the NX documentation, in the Advanced Dynamic Analysis User's Guide there is an example carried out in the Nastran environment.
However, it is difficult to know how to perform it only by looking at that part.
2. Is sol103(Normal mode analysis) also applicable for viscoelastic?
I look forward to your advice.
