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.
Contact in ABAQUS
I am not sure but I think there was an option called self contact or ... which was applicable whenever the surface contacted itself any where, which could be helpful in this case. Or may be that is the same as General contact that you already mentioned?
