Option to perform boundary acoustic analysis when a virtual fluid mass boundary is specified. The acoustic boundary is defined using MFLUID and ELIST Bulk Data entries in the same manner as virtual fluid mass. PARAM, ACBVC is used to specify the speed of sound in the fluid medium. PARAM, ACBPRESSET defines pressure output points in the fluid via SET Case Control commands. PARAM, ACBREFPRES is used to convert sound pressure to decibels. PARAM, ACBINTERACTTOL is used to specify the tolerance for removing negligible off-diagonal acoustic coefficient interaction terms from the assembled acoustic coefficient matrix to reduce memory requirements and improve performance. |
