Thank you I will try to fix the issues.

I am trying to simulate the effect of gravity on an object (breast). The breast under-goes large deformations because of gravity, the pendulum length of breast almost doubles between the positions am interested in. So far, I could simulate homogeneous (single domain breast tissue) breast models...

Hi, Thanks it works as you say with default load ramping up. I am interested in the final equlibrium state only. Thank you again!

Units I am using are Length=mm; density =Tonne/mm3; neo-hookean coefficent = MPa ; acceleration due to gravity = mm/s2;

I agree with you, I have tried to find the reason behind it but couldnt figure it out in long time. Attach is inp file for the standard analysis. http://files.engineering.com/getfile.aspx?folder=8cadf883-c682-4271-be33-5797541dc869&file=pat_homo_coarse.inp

Just a small additional information on my post, for explicit analysis I used the default settings in the ABAQUS CAE.

I am trying to simulate the effect of gravity on an object (breast). The breast under-goes large deformations because of gravity, the pendulum length of breast almost doubles between the positions am interested in. Initially I used static, general analysis and I got error "Error in job Job-1...

I get the same error. Attach is my CAE, please can you see if you get the same error: Error in job job_disp: Problem during linking - Abaqus/Standard User Subroutines http://files.engineering.com/getfile.aspx?folder=4d9ab3bf-3653-4a8a-baaf-400f88d5a60b&file=DISP_6.12.cae

ohh :), I actually tried it but with CAE gives the error I posted last. Also its the same error if try to run it in throguh comand line as well with the input and subroutine file from the current version. Can you send me your files, I can try them to test if something is wrong with my set-up...

Before I was using different version of CAE (6.12) to run the example from older version (6.11). I just tried to run in latest example in comand line, in case CAE was missing stuff during import from .inp file I still get the same message (mentioned below). In your run do you get the last line...

Thanks, things are moving forward. After getting gfortran (4.6) and changing the env file, and while running the ABAQUS example I get following error: Error in job Job-1: Problem during compilation - /home/prab/udispxxx.f Prab

Thanks sdeback, what all exactly I need to change in env file?

I dotn have Intel Fortran Complier, I will get it. For the Visual Studio, is it possible to get it for Linux? Thanks Prab

I am not getting any warnings/errors, the job just stays with the submitted status. I am adding the subroutine through job (in the general tab). I reckon somehow the subroutines are not being recognized/processed. Thanks Prab

Thanks, Actually I havent namaged to run *any* subroutine on my machine. After your comment, I tried to run the example given by Abaqus in DISP example: udispxxx.inp and udispxxx.f. This example didnt run either, the system just shows job submitted and nothing else happens. What should I do...

Hi, I want to use discrete set of displacements as BC for individual nodes, therefore am trying to use a user subroutine DISP. I have been struggling with writing a user subroutine (DISP) in ABAQUS. After using lot of help from various forums, people. I have managed to write the subroutine...

Thank you sdebock, I understand it much better. I think its just the syntax I have to stuggle with now. This is what I have comeup as: SUBROUTINE DISP(U,KSTEP,KINC,TIME,NODE,NOEL,JDOF,COORDS) C INCLUDE 'ABA_PARAM.INC' C DIMENSION U(3),TIME(1),COORDS(3) C delta_U array...
