Mapdl.mfsurface(inumb='', fnumb1='', label='', fnumb2='', **kwargs)

Defines a surface load transfer for an ANSYS Multi-field solver

APDL Command: MFSURFACE analysis.

  • inumb – Interface number for load transfer. The interface number corresponds to the interface number specified by the surface flag FSIN (SFxxcommands).

  • fnumb1 – Field number of sending field.

  • label – Valid surface load labels:

  • fnumb2 – Field number for receiving field.


This command is also valid in PREP7.

The ANSYS Multi-field solver solver does not allow you to switch the load transfer direction for the same load quantity across the same interfaces for a restart run. For example, if Field1 sends temperature to and receives heat flow from Field2 across Interface 1 in a previous solution, then you cannot make Field1 send heat flow to and receive temperatures from Field2 across the same interface in a restart run, even if you cleared the corresponding load transfer command.

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.
