Comments
- Assuming that there are N acoustic superelement models that share a single contiguous fluid cavity, PARAM,ACMTXNO,YES can be added to N-1 of these superelement generation models to avoid storing the reduced fluid mass, fluid stiffness, and fluid damping matrices in all the N-1 superelements. The Nth superelement can be generated without this parameter and these N superelements can then be used in a residual run. These superelements can also be turned into design variables using DMIGDV on CMSMETH.
- The physical fluid cavity can be optionally included/excluded in the residual run.
