User subroutines in ABAQUS

I have been using an Abaqus dll created using a user-defined routine. Things work well on a serial case. The issue comes when I try to use it in parallel. I am trying to do this on windows 7. The error I get is

forrtl: severe (59): list-directed I/O syntax error, unit 12,

in Fortran I/O but I do not get this error when I run the simulation serially. Any ideas will be helpful.

Thanks

I always use "Microsoft Visual Studio 11.0" and "Intel\Composer XE 2011 SP1" to apply all the user subroutines.

Recently, the university administrator updated the Visual Studio to 2105 (14.0) on my lab computer. 

When I tried to run an OLD simulation which WORKED perfectly before, it returned me the error message below:

Begin Linking Abaqus/Standard User Subroutines

   Creating library standardU.lib and object standardU.exp

I am only seeing a "x" for a UEL at its first node. And I dont see any other node of UEL. Is it correct or some problem is there?
I also want to calculate the strain energy for whole model(including UEL). But in history output I am only seeing strain energy of Abaqus defined elements under "whole model strain energy". Can some one please help me in calculating strain energy of whole model including UELs 

Here you can find a sample codes along with documentation:

Hi everybody,

I'm writing a User Difined Element (UEL) for my research.

Would you please let me know if it's possible to call a file (txt, dat, etc) inside of the UEL or not?

Example:

    IF (LFLAGS(3)=1) THEN
        OPEN (UNIT = 10, FILE = "AAA.dat", STATUS = "OLD")
        READ (10, *), StiffnessTable
        AMATRX=StiffnessTable
    END IF

Thanks in advance,

This subroutine using VUSDFLD is to
determine position of damage and provide evolution of damage surface, when some
elements failed. The “outer” damage status will transfer to “inner” damage
status.

Now the problem is that when I read the
coordinates of material points, using coordMp（k,1),coordMp（k,1),coordMp（k,1), it returns wrong locations. Then I
tried a very simple loop:

Hi all,

I would like to use Dflux to give a Temperature and dT/dt related heat flux. Can Dflux be used for this purpose? I am not sure how to get dT/dt ? Or other subroutine can fulfill this purpose?

Thank you 

Dear valuable members,

Thanks for the kind help in advance.

I would submit a well known error that I got in my run of
the UEL subroutine which has additional dof. the error is:

Abaqus Error: The executable

I'm new in the computer simulation of adaptive bone remodeling (Bone will adapt to the loads it is placed under). And I know many research cases of numerical model were implemented as FROTRAN subrountines for the software package ABAQUS: the bone material properties will be updated by the subroutine.

I know FROTRAN is excellent at handling large data sets for scientific coumputing and requires less resources, but I haven't learned the FROTRAN.I wonder what else irreplacable advantages of  FROTRAN in the bone remodeling? 

Hello every one....

I am new in abaqus/cae, abaqus/explicit.  I have googled but not able to get any tutorial or example for metal cutting with chip formation. just few youtube animation videos are available on 3D orthogonal cutting, milling. But now such video or doc is available.

So, if any one having any kind of tutorial, example, or short notes.. please please share with me or mail me on my ID badwl24@yahoo.com.

it will be great help for me.  thanks in advance.... please please anyone!!!!!!!!

Hi!

I'm already simulating a shape memory alloy behavior with the aid of the HETVAL subroutine, but I'd like to use UMATHT instead, since the HETVAL can't simulate correctly heat absortion(cooling down).

I've tried to add the required values for UMATHT without achieving a correct phase fraction simulation, and some times even no compilation of the .for file.

Is there any other examples that uses UMATHT besides the Stefan problem?
Any other recommendation about HETVAL to UMATHT migration?

Hi,

I am currently trying to simulate the wear of a damper within a gas turbine using Abaqus 6.9 and the user-subroutine Umeshmotion. I have managed to get the subroutine to compile correctly but Abaqus does not appear to use it as I can change the wear value within the code and it makes no difference to the results.

Has anyone had the problem where Abaqus does not appear to use a subroutine even though it compiles correctly? Any hints on how to fix this would be greatly appreciated.

Many Thanks

Joe
