How to define Pressure release boundary condition (P = 0) in SC3D Nastran Acoustic SOL 103?
Setup Pressure release boundary condition (P = 0) in Nastran SOL 103
In Simcenter 3D, the acoustic mode solution only support boundary conditions V=0 (default everywhere). Pressure P=0 is not supported in the SC3D graphic user interface. However, the boundary condition P=0 is supported in the Nastran solver. Just solve the modal solution using option “Write Edit & Solve Input File”, this allows you to edit the input file first before solving. Add the following lines to the input file:
