Hello All,
I have written a user material behavior using VUMAT for hyperelastic materials.
I am validating VUMAT on a flat square plate.
1. The plate is subjected to uniaxial loading.
2. It has 4 structured quad elements.
3. One side of the plate is fixed and the opposite side is subjected to shell edge load.
4. The element is of type S4R.
How can I run an analysis that starts in Abaqus/Standard and can be continued in Abaqus/Explicit? Does Abaqus automatically take care of data exchange between them or it should be manual. In other words, can I define step1 in a model run by Abaqus/Standard then immediately running step2 under Abaqus/Explicit?
Thanks,

I am trying to call VUSDFLD subroutine before VUMAT. I need to access some variables which are not available in VUMAT. Does anyone know how I can force ABAQUS into calling VUSDFLD before VUMAT? Thanks.

I am trying to run UHYPER in ABAQUS 6.9EF1. I have the following questions:
1) How can I get the nodes
ID associated with element# NOEL in UHYPER subroutine?
2) How can I get the
coordinates of the displaced nodes associated with element# NOEL in UHYPER
subroutine in the middle of the simulation? I tried to use GETVRN but it seems it does not work in
UHYPER.
