MFCONV

MFCONV, Lab, TOLER, --, MINREF
Sets convergence values for an ANSYS Multi-field solver analysis.

Compatible Products: – | – | – | Enterprise | Ent PP | Ent Solver | –

Lab

Valid labels:

Force labels: FX, FY, FZ
Displacement labels: UX, UY, UZ
Temperature label: TEMP
Heat flux label: HFLU (for surface load transfer)
Heat generation label: HGEN (for volume load transfer)

If Lab = ALL, MFCONV applies the convergence value to all nine variables.

TOLER

Convergence tolerance about program calculated reference value (the L2 norm of the new load in a multi-field analysis). Defaults to 0.01 (1%) for all labels. Must be less than 1.0.

--

Unused field.

MINREF

The minimum value allowed for the program calculated reference value. If negative, no minimum is enforced. Defaults to 1.0e-6 for all labels. Not available in the GUI. MINREF corresponds to ||ϕnew|| as defined in Set up Stagger Solution in the Coupled-Field Analysis Guide.

Notes

MFCONV sets convergence values for variables at the ANSYS Multi-field solver interface.

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.

Distributed ANSYS Restriction This command is not supported in Distributed ANSYS.

Product Restrictions

ANSYS Mechanical allows MFX analyses but not MFS analyses. ANSYS Multiphysics allows both MFS and MFX analyses.
