i am very new to abaqus and i want to simualte sliding wear between a pin and a disc. i found from the literature that by using user subroutines we can calculate the wear. i am not getting how to use a user subroutine , can any one expain how to use user subroutines in the CAE. is there any simple example problems in understanding this user subroutine functions. thanks in advance.
Question for post-processing after each increment and return it back to calculation (non-local damage)Submitted by zjyounger on Fri, 2011-06-10 20:04.
I am trying to use a nonlocal damage criteria to simulate the crack growth, which can reduce the mesh dependency.
In abaqus, VUMAT/UMAT is doing computation at integration point for each increment, but I want to do the post-processing after each increment to get the non-local state variable and return this value back to calculation.
Hi Abaqus experts
I am hoping that you can help me getting a element user subroutine writen in fortran f90 to work in Abaqus. I have made the simplest 8 noded brick element element that i can think of. I has a zero thickness and only has some simple definitions of the parameters ESTIFF,RHS,SVARS and PNEWDT. I have made a model with one single element of this user element where the upper part is displaced from the lower part which are fixed.
When I try to run the model I get the following message in the log file:
"Abaqus Error: The executable C:\SIMULIA\Abaqus\6.10-2\exec\standard.exe
aborted with system error code 5.
Please check the .dat, .msg, and .sta files for error messages if the files
