Reply To: CONTACT FORCES IN LSDYNA

[Alex R.]

Hello, 

In the desribed case it would be recommended to define the mat as SURFA and the cylinder as SURFB in *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE (SURFATYP = 3, SURFBTYP = 3). Adding keyword *DATABASE_RCFORC will provide a data about contact forces between the mat and cylinder. 

Please let me know how it goes.
