Hello everyone,

I'm trying to simulate an explosion with ALE contact (type Lagrangian_in_solid, ALE_Multi_Material_Group) on a simple mesh box. But I get a strange error message when I start a job:

*** Warning 21292 (STR+1292)
     Load curve ID 37 of *MAT_SIMPLIFIED_RUBBER/FOAM ID 1
      covers only the tensile range. It should include both the
      tensile & compressive range to ensure it describes the
      complete range of loading

 *** Warning 21293 (STR+1293)
     The abscissa for load curve ID 38 used for material ID 181
     is decreasing. This is not permitted and may result in strange behavior.

I had already used mat_181 with the same stress-strain curves without control_ALE, and it worked. Do you have any idea how I can solve this problem? When I start a job with a simple curve in the mat_181 and no table to define the load curve. I don't get this error message.

Thank you for your understanding.
