Mapdl.imesh(laky='', nsla='', ntla='', kcn='', dx='', dy='', dz='', tol='', **kwargs)

Generates nodes and interface elements along lines or areas.

Mechanical APDL Command: IMESH

Parameters:

lakystr

Copies mesh according to the following:

• LINE or 1 - Copies line mesh (default).

• AREA or 2 - Copies area mesh.

nslastr

Number that identifies the source line or area. This is the line or area whose mesh will provide the pattern for the interface elements. Mechanical APDL copies the pattern of the line or area elements through the area or volume to create the mesh of area or volume interface elements.

ntlastr

Number that identifies the target line or area. This is the line or area that is opposite the source line or area specified by NSLA. Add NTLA to obtain the copied mesh from the source line or area.

kcnstr

Number that identifies the particular Mechanical APDL coordinate system.

dxstr

Incremental translation of node coordinates in the active coordinate system ( DR, Dθ, DZ for cylindrical, and DR, Dθ, DΦ for spherical or toroidal). The source line or area coordinates + DX, DY, DZ = the target line or area coordinates. If left blank, Mechanical APDL automatically estimates the incremental translation.

dystr

Incremental translation of node coordinates in the active coordinate system ( DR, Dθ, DZ for cylindrical, and DR, Dθ, DΦ for spherical or toroidal). The source line or area coordinates + DX, DY, DZ = the target line or area coordinates. If left blank, Mechanical APDL automatically estimates the incremental translation.

dzstr

Incremental translation of node coordinates in the active coordinate system ( DR, Dθ, DZ for cylindrical, and DR, Dθ, DΦ for spherical or toroidal). The source line or area coordinates + DX, DY, DZ = the target line or area coordinates. If left blank, Mechanical APDL automatically estimates the incremental translation.

tolstr

Tolerance for verifying topology and geometry. By default, Mechanical APDL automatically calculates the tolerance based on associated geometries.

Notes

Generates nodes and interface elements along lines or areas. The imesh command requires that the target line or area exactly match the source line or area. Also, both target and source lines or areas must be in the same area or volume. The area or volume containing the source line or area must be meshed before executing imesh, while the area or volume containing the target line or area must be meshed after executing imesh.

For three dimensional problems where LAKY = AREA, Mechanical APDL fills the interface layer as follows: This command contains some tables and extra information which can be inspected in the original documentation pointed above.
