Postdoc position in Solid Mechanics at Lund University, Sweden
The postdoc position is mainly focused on
development of advanced computational models of microstructure evolution
in metallic materials, with particular focus on recrystallization and
related phenomena. Some experimental activities may also be part of the
work.
The employment is for one year with a possible extension to two years.
A more detailed job description and procedures for
application can be found here .
Adding static/dynamic library to an Abaqus user subroutine
I want to use an external subroutine in my umat but I have not been able to do that so far. Having created a dynamic library project in Visual Studio 2008, I have created a .dll and .lib files and copied the .lib file into the working directory of my abaqus job and the .dll file to exec folder. I have also added the directory of the .lib file in the LIB environmental variable. But I get these errors from ABAQUS:
[quote]LINK : fatal error LNK1181: cannot open input file 'Dll2.lib'
Sample code for Abaqus subroutines
Here you can find a sample codes along with documentation:

Nonlinear analysis using ANSYS
Hi ,
I am performing a nonlinear analysis (ANSYS) of GRP pipe which is subjected to diametral compression ,
i am appling a line load in steps of 0.05 increments until load reaches a maximum value of 40kN in 20 steps
i have got convergence till 13 steps but unable to get convergence in next further steps , i am getting error as LSSOLVE looping is stopped because solution is unconvergent and NCNV, 1set
Obtain Load-displacement curve from Abaqus/Explicit analysis via Python
Hi, all,
I'm quite sure we can use Python read displacement and load for certin node set from Abaqus odb result file and then plot X-Y data (That's all I need). I has been struggling for a whole week to find out a good solution. I've many resources out there but nothing has been worked out though. So, I wonder if anyone knows how to address this issue or even share me a link. I really appreciate it!
Thanks.

not smooth F-D curve_Simulation of indentation with elastic-plastic model
Dear all,
I have a problem now:
I simulated indentation on a elastic-plastic model with a rigid
indenter, the elastic ideal plastic with von mises stress model in
ABAQUS is used. A contact pair is applied to calculate the contact between the indenter and the sample.
The problem is that the obtained the force-displacement data in the loading part, which contains the plastic deformation
is not smooth, but in the unloading part is smooth. But if a model
Stiffness Matrix (AMATRX) with complex numbers in UEL
Hi everybody,
I'm working on UEL. The stiffness matrix (AMATRX) which I have
defined is consisting of complex numbers (real and imaginary part).
When I'm running it I'm getting this error message:
Abaqus Error: The executable standard.exe aborted with system
error code 1073741819. Please check the .dat, .msg and .sta files for
error messages if the files exist. ...
I checked the files and no error message was found.
When stiffness matrix is just real numbers, it's working perfectly.
