Comments
- Only the plane type of rigid wall is available
for /RWALL/THERM. Coordinate of M and M1 are used to define
the normal of the plane.

Figure 1. - The first input format used to define the rigid wall is the coordinates of point M, at the location of the rigid wall.
- The second input is the coordinates of point M1, defining the outward normal direction of the wall.
- The secondary nodes can be defined as a list of nodes and/or as the nodes initially at a distance less than Dsearch from the wall.
