Hi,
Iam doing drop test for electronic unit. for this i have meshed my unit in optistruct user profile. after that i have changed my userprofile to radioss and created loads and boundary conditions. updated my elements to shell4N elements from elements config option. but iam getting error as Error input consistency
2D sOLIDS(Quad & Tria)are not compatible with N2D3D=0
what does mean by N2D3D=0, how can i come from this.
