Summary

No support ACPRESS boundary condition from the UI in SOL 103. Workaround: One can create a regular SOL 103 Acoustic solution and then edit the *.dat file with adding the ACPRESS boundary condition.

Details

ACPRESS is not supported in UI, one can add this card for applying pressure BC in dat file before solving. Below is sample format.

ACPRESS 3 REAL1.000000 0.0000 0.0000 1+
+ THRU 121

3 is card ID, Real and imaginary values are zero applied to nodes 1 to 121.
