Dear friends,
I want to generate a substructure, on which i would like to perform a modal analysis. Here is how i am trying to do that:
- Step --> Substructure generation
- BC --> Retained nodes
- Job
afterwards I am trying to add an additional step of frequency analysis, and in Field Output i select substructure. However, Abaqus only performs modal analysis for the entire structure. Why so?
For the sake of simplicity I am in this stage only interested in
- Guyan reduction
- Dynamic condensation.
Thankful for appropriate answers with details
