defining interaction between a lot of surfaces in abaqus.
Dear all:
During simulation in ABAQUS , I encountered a severe problem . I used ABAQUS Explicit but I could not define the interactions between for example 200 particles.I mean I used surface-to surface contact (explicit),so I had to define many many interactions between every particle with the others ,which is waste of time.It seems that I have to use General contact(explicit) ,but by using general contact (explicit),an error occured which says :"CONTACT currently does not support the use of 2D surfaces".
I appreciate any ones help.
