1.	An ALE rigid wall is defined by its normal and either the coordinates of one point.

2.	The first input 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 is the coordinate of a point M1 and eventually a point M2 (in case of a moving wall M1 and M2 have the same motion as node_ID).

4.	The slave nodes can be defined as a list of nodes and/or as the nodes initially at a distance less than Dsearch from the wall.

5.	Coordinates XM1, YM1, and ZM1 are read only if, Type = PLANE, CYL, or PARAL.

6.	For parallelograms, the normal is defined using:

M or node identifier node_ID in case of a moving rigid wall
