Hi,
While working through the tutorial, I have run into a problem with tutorial 9.
I have even redone the entire model, step by step but I cannot seem to find the source fo the error.
Right now the errors are:
Thereś a number of things that kind of bother me, hope someone can help clarify them for me:
1) When I select elements (for mesh editing), clicking "Invert" does not do a lot (in fact, only seems to add a kind of shadow to the elements?)
2) When welding the two meshes, choosing the given threshold does not really seem to do anything, so to exclude uncertainties I just went with the "Weld" option given during "Attach"-ing the meshes.
3) What is the difference between absolute and relative moving/rotating? Is it with respect to the original and current frame of reference/ coordinate system, respectively?
4) When adding the Rigid Constraint>Prescribed force for the indentor, should I leave prescribed force in z-direction as 0, and then only edit the value in the load curve?
5) In the analysis step, is it correct that the second point is (1 000 , 200) rather then (10 000 , 200)?
Thanks a lot
PS: I have attached my files for reference
