Hi Anush,

Are you trying to apply MPCs based on geometry, or based on mesh?

If you're using geometry, then you can use edges and vertices, but if you're using meshed parts/instances, you would have to work with nodes. I am not sure whether the "es" object in your first code line is a list of edges.

If you wanted to link a vertex to an edge, you could use something like

a = mdb.models['Model-1'].rootAssembly

v = a.instances['Domino-1'].vertices

e = a.instances['Domino-1'].edges

mdb.models['Model-1'].MultipointConstraint(name='Constraint-1',

controlPoint=v.findAt( (5.,15.,5.), )., surface=e.findAt( (5.,15.,5.), ), mpcType=LINK_MPC,

userMode=DOF_MODE_MPC, userType=0, csys=None)

The "#400801..."  line represents a mask to select a sequence of nodes from the list of all nodes in your part. According to the scripting reference manual, "When large number of objects are involved, this method is highly efficient"

Hi Shyam,

                  Thanks for your reply. Ya im using meshed based  MPC , so when i use getsequence from mask how to give the input argument???

Hi Anush,

If you;re doing MPCs by nodes, all you need to pass to the MultipointConstraint function are node sequences for the controlPoint and surface parameters.

You can use the getByBoundingBox function to get both of these, as explained in this thread at imechanica:

Thanks Shyam 

You have any idea on linking Abaqus 6.12-3 with fortran for running Subroutines???.

I have Visual basic 2008 and Intel fortran composer xe 2013 compiler

I have done that, but you need Intel fortran 11 for user subroutines in Abaqus 6.12. I think composer 2013 can be thought of as intel fortran 13/14.

If you can get fortran 11 and visual studio 2010, I have a batch file that I use to set environment variables so that everything works. This is of course, with a 64-bit windows 8 running on a 64-bit processor.

Hi Shyam thanks for advice i gt the Intel compiler right but  there is an error showing up.plz refer the attached image

Hi Anush,

I think you should look for "vcvarsall.bat". I've got it installed in the Program Files (x86) folder ( "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\vcvarsall.bat" ). That should set the path to the linker and other linker files correctly.

I have attached the batch file that I use to set the environment on my system (renamed as .txt to avoid upload issues). It should work with slight modification for you.

Shyam, 

               Shyam i changed the Visual studio to 2008 version and gt  that one right but even after changing the  path variable i get everything has pass but at the end there is an error.

Error in the user_std.log is 

LINK : fatal error LNK1104: cannot open file 'kernel32.lib'

But after searching net i found that 

"C:\Program Files\Microsoft SDKs\Windows\v6.0A " this should have lib and include but in my computer both the folders are not there. so how to install them seperately

Shyam,

                 Finally got everything right,thanks a lot for your help.

Good for you. I am actually curious as to what the steps you followed were.

Would you mind explaining your procedure?

Shyam,

1. Installed Visual studio 2008 with full installation

2. Installed Fotran 11.1.048 again with full installation

3. pasted  " C:\Program Files\Microsoft Visual Studio9.0\VC\bin\ x86_amd64 \  vcvarsx86_amd64" && "C:\Program Files\Intel\Compiler\11.1\048\bin\ia32 \ifortvars_ia32" &&       in the target of the abaqus command

4.  After pasting The target will be like this

"C:\Program Files\Microsoft Visual Studio 9.0\VC\bin\x86_amd64\vcvarsx86_amd64.bat" && "C:\Program Files\Intel\Compiler\11.1\048\bin\ia32\ifortvars_ia32.bat" && C:\Windows\System32\cmd.exe /k

5. Then i Got an error : LINK : fatal error LNK1104: cannot open file 'kernel32.lib'

for which i used repair under visual studio 2008 and repaired the entire VS2008

Now when i link the user subroutine it is showing 

"problem during compilation" You have any idea to solve this??

Can you try to make abaqus just compile your user code, and paste the error message here?

You can use "abaqus make user="

Do mean the Subroutine .for file in place of user material code file???

Im using Python code(Run script) for getting the node set for applying MPC. I get the Nodesets as:

 '*MPC,MODE=NODE,USER \n 1,Part-1-1.5,Part-1-1.1 \n *MPC,MODE=NODE,USER \n 1,Part-1-1.7,Part-1-1.3 \n '  

now my doubts is how to link these codes with fortran or fortran will automatically take them from my CAE file??

Ah ok, I get it now, you are creating MPC keywords from CAE, but the MPC type is USER.

So you will be defining the MPC subroutine in your user subroutine code right?

All of the nodes which participate in your *MPC keyword will automatically be passed to the MPC subroutine by Abaqus. In my previous answer, I meant for you to try to compile the .for file with the MPC subroutine.

I tried running my friend's subroutine which was working properly in his system but that also is resulting in same error in my computer- Abaqus/ User subroutine linking error

Shyam,

                  The Subroutine is linked and is working fine i made a minor mistake

here is the procedure

1. Installed Visual studio 2008 with full installation

2. Installed Fotran 11.1.048 again with full installation

3.Abaqus CAE -Properties-Target Should be like this

 "C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\vcvarsamd64.bat" && "C:\Program Files (x86)\Intel\Compiler\11.1\048\bin\intel64\ifortvars_intel64.bat" &&C:\SIMULA\Abaqus\Commands\abq6121.bat cae || pause

4. Abaqus Command -target should be like this

"C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\bin\amd64\vcvarsamd64.bat" && "C:\Program Files (x86)\Intel\Compiler\11.1\048\bin\intel64\ifortvars_intel64.bat" &&C:\WINDOWS\SysWOW64\cmd.exe /k

Thats It. No repairing of VS 2008 needed if the above procedure is done.
