Schlitz um Kalotte mit ABEC simulieren. Wie?

Code:
Control_Solver
  f1=500                     // First frequency
  f2=20000                  // Last frequency
  NumFrequencies=100        // Number of frequencies
  Abscissa=log              // Distribution of frequencies
  MeshFrequency=20000Hz     // Frequency up to which analysis is valid
  Dim=CircSym               // Circular symmetric model
  NUC=true                  // NUC can be applied because interface is extruded.
