PARAM, ACMTXNO
Bulk Data Entry This parameter sets preferences for storage of reduced fluid mass, fluid stiffness, and fluid damping matrices for acoustic superelements.
Parameter  Values  Description 

ACMTXNO  <YES, NO> 

Comments
 Assuming that there are N acoustic superelement models that share a single contiguous fluid cavity, PARAM,ACMTXNO,YES can be added to N1 of these superelement generation models to avoid storing the reduced fluid mass, fluid stiffness, and fluid damping matrices in all the N1 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.
