+ ## Add orientation parameters. \em params is a dictionary containing one or
+ # several orientation parameters. The valid parameters are:
+ # - "VECT_Y": Triplet defining the local Y axis (the X axis is the
+ # main direction of the 1D element).
+ # - "ANGL_VRIL": Angle of rotation along the X axis to define the local
+ # coordinate system.
+ # The parameters can be specified several times. In this case, only the
+ # last "VECT_Y" or "ANGL_VRIL" is taken into account.
