How to Apply Contact Condition for NURBS Solid Patch
Hello everyone, I want to tie to two solid NURBS patches, I apply the NURBS_TIED_NODES_TO_SURFACE contact, but when I run the analyze a get the error message: error 20011 reading *CONTACT_NURBS undefined node # 1, if anyone can help me with this.
Thank you for all.
Hi @hafit38,
Try double checking that the SSTYP and MSTYP are set correctly with what your SSID and MSID are. For example, you might think you are trying to reference a part set as your ID but you actually have the type set to be a node set, so it's not finding it. This is all just a guess on my part.
You can also try changing the constraint formulation between mortar method and point to point to see if that helps.
If neither of those help, try flipping the slave and master side of the contact or try changing the SSTYP and MSTYP to try something else.
Disclaimer: I have never used NURBs in Dyna, I'm just using general contact knowledge to help you with your situation.
Let me know if this helps you at all!
@negativevolume thank you for your answer, the problem comes from NURBS_CONTACT which is obsolete and will soon be removed from LSPP.
