Comments

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


    Figure 1.
  2. The first input format used to define the rigid wall is the coordinates of one point M or a node identifier node_ID in case of moving rigid wall.
  3. Next input format is the coordinate of a point M1.
  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.
