- Mapdl.ndsurf(snode='', telem='', dimn='', **kwargs)¶
Generates surface elements overlaid on the edge of existing elements
APDL Command: NDSURF and assigns the extra node as the closest fluid element node.
snode – Component name for the surface nodes of the solid elements.
telem – Component name for the target fluid elements.
2 - 2-D model.
3 - 3-D model.
This command macro is used to generate surface effect elements (SURF151 or SURF152) overlaid on the surface of existing plane or solid elements and, based on proximity, to determine and assign the extra node (FLUID116) for each surface element. The active element type must be SURF151 or SURF152 with appropriate settings for KEYOPT(4), KEYOPT(5), KEYOPT(6), and KEYOPT(8).
The surface nodes of the plane or solid elements must be grouped into a node component and the fluid elements must be grouped into an element component and named using the CM command. The names must be enclosed in single quotes (e.g., ‘NOD’) when the NDSURF 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, SURF152, and FLUID116 element types.
