Subject: | [Getfem-users] Contact forces in Large Sliding Contact Brick |
Date: | Fri, 21 Jun 2019 12:49:55 +0200 |
Hello
everyone, I have a question about the 'Large-Sliding-Contact'-Brick. I use this large sliding contact brick to create a contact between two different bodies. Now I need to read the contact forces between those two bodies. Therefore I use the command: force = gf_model_get(md, 'variable', name_of_multiplier) However, I'm not sure how the contact forces are outputted by the function mentioned. Are they outputted in the global coordinate system (fg_x,fg_y), or are they outputted in a local element system (fl_x,fl_y), or are they outputted with respect to the contacting surface e.g. normal-force an tangential-force (fn, ft). I didn’t find any detailed information for the contact forces in the user documentation. Is there any? I hope you can help me out with this problem. Best regards, Moritz |
