mfrelax

Mapdl.mfrelax(lab='', value='', option='', **kwargs)

Sets relaxation values for an ANSYS Multi-field solver analysis.

APDL Command: MFRELAX

Parameters:

lab

Valid labels:

value

Relaxation value. Defaults to 0.75 for all labels.

option

Valid options are:

RELX - Uses relaxation method for load transfer (default).

LINT - Uses a linear interpolation for loaf transfer.

Notes

MFRELAX sets relaxation values for the load transfer variables at a surface or volume interface. Option = RELX will usually give you a more stable and smooth load transfer and is suitable for strongly coupled problems (such as FSI problems). Option = LINT is suitable for weakly coupled problems because it will transfer the full load in fewer stagger iterations.

See the MFFR and MFITER commands for more information on relaxation in the ANSYS Multi-field solver.

This command is also valid in PREP7.

See Multi-field Commands in the Coupled-Field Analysis Guide for a list of all ANSYS Multi-field solver commands and their availability for MFS and MFX analyses.
