I have VUMAT code for visco-plasticty material.
When I use this code for abaqus 6.10 input file it works fine.
If i create same problem(one element check) in abaqus 6.13 and run in cluster with abaqus 6.11 it is not working.
Getting error like below.
***ERROR: Floating Point Exception detected in increment 2722. Job exiting.

Hello all:
I have bee trying to run the benchmarks problems, but for some reason I'm unable to obtain the expected results. I'm trying the built the strength envelope that is presented in the manual. The envelope defines different maximum axial stress depending on the orientation of the discontinuities with respect of the loading direction.
Dear everyone
My project is about the adhesional friction between rubber and a rigid surface. In this case I have modeled a block of rubber which is sliding on a real rough rigid surface in ABAQUS.
My Masters thesis work is on fatigue crack growth analysis on microalloy steel using cohesive zone model for mode-I crack growth.I had seen papers
on cohesive zone model which is attached here,in that damage based cohesive model is implemented. I would like to know how can we implement
damage mechanisms in ABAQUS,means whether it is necessary to write UMAT or UEL for the same?
can any one give me some suggestions?
Looking forward to your reply.
thank you very much.

To use cohesive elements, normally user can add a layer of elements between neighbouring node pairs. This matlab code can help you to process that especially your FE mesh is irregular. The code, the initial .inp file and corresponding out put files are attached for a better illustration. The new generated cohesive elements won't cause any trouble in the element number. Also you can apply this code to generate new UMAT elements in mesh.
Dear colleagues,
