msolve

Mapdl.msolve(numslv='', nrmtol='', nrmchkinc='', **kwargs)

Starts multiple solutions for random acoustics analysis with diffuse

APDL Command: MSOLVE sound field.

Parameters:

numslv

Number of multiple solutions (load steps) corresponding to the number of samplings. Default = 1.

Notes

The MSOLVE command starts multiple solutions (load steps) for random acoustics analysis with multiple samplings.

The process is controlled by the norm convergence tolerance NRMTOL or the number of multiple solutions NUMSLV (if the solution steps reach the defined number).

The program checks the norm convergence by comparing two averaged sets of radiated sound powers with the interval NRMCHKINC over the frequency range. For example, if NRMCHKINC = 5, the averaged values from 5 solutions are compared with the averaged values from 10 solutions, then the averaged values from 10 solutions are compared with the averaged values from 15 solutions, and so on.

The incident diffuse sound field is defined via the DFSWAVE command.

The average result of multiple solutions with different samplings is calculated via the PLST command.
