Mapdl.lfsurf(sline='', tline='', **kwargs)

Generates surface elements overlaid on the edge of existing solid

APDL Command: LFSURF elements and assigns the extra node as the closest fluid element node.


Component name for the surface lines of the meshed solid areas.


Component name for the target lines meshed with fluid elements.


This command macro is used to generate surface effect elements overlaid on the surface of existing plane elements and, based on proximity, to determine and assign the extra node for each surface element. The underlying areas of the solid region and the fluid lines must be meshed prior to calling this command macro. The active element type must be SURF151 with appropriate settings for KEYOPT(4), KEYOPT(5), KEYOPT(6), and KEYOPT(8).

The surface lines of the solid and the target lines of the fluid are grouped into components and named using the CM command. The names must be enclosed in single quotes (e.g., ‘SLINE’) when the LFSURF command is manually typed in.

When using the GUI method, node and element components are created through the picking dialog boxes associated with this command.

The macro is applicable for the SURF151 and FLUID116 element types.
