Comments

  1. 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.
  2. The first input format used to define the rigid wall is the coordinates of point M, at the location of the rigid wall.
  3. The second input is the coordinates of point M1, defining the outward normal direction of the wall.
  4. 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.
