Hi,

I am attempting to couple a moving multi-body load to a surface using ABAQUS/explicit, i.e. the loading varies depending on the surface displacement at the previous time step.

I realise that VDLOAD cannot access values such as element displacement directly but can access variables using tools such as utility subroutines e.g. UEXTERNALDB.  The only problem is that such utility routines only seem to work for ABAQUS implicit.

Similarly vgetvrm can be used to output stress values but not displacement.

I image VUEL could be used to apply loading in this manner…but how?

Thankyou
