ABAQUS

Dear iMechanica users,

I have a problem which I would appreciate any input on how to solve. I have an indentation problem, in which I indent a cell with an enclosing membrane. Therefore, I create contact between the (rigid) indenter and membrane, and tie the membrane and intracellular solid elements together. The model is an axisymmetric model, with CAX3 and CAX4R making up the intracellular axisymmetric solid elements and SAX1 the axisymmetric membrane.

Hi everyone,

I'm using UEL in ABAQUS. My model just has one 4-node element (defined in UEL) fixed in one end. When I'm running the UEL, it's working without any problm. But when I' trying to print out the global stiffness matrix I'm getting this error: "aborted with system error code 1073740940".

This is the way that I'm trying to print it out:

*STEP, NAME=STEP-1
*MATRIX GENERATE, STIFFNESS
*MATRIX OUTPUT, STIFFNESS
*END STEP

Would you please let me know what's the problem and how I can fix it?

Regards,

Dear all,

I want to write a python script for ABAQUS in which I can define a path for post-processing purposes. Getting the nodes which lie on the path is easy because they all lie on one edge, so with

myNodes=myEdge.getNodes()

I get the list of nodes.

Now the problem:

Hi everyone;

I'm trying to simulate FSW plunge state using Abaqus/Explicit, Coupled Eulerian-Lagrangian technique.

As you can see in the picture, NT11, PEV and EVF are calculated. But the problem is that the elements in base metal are not deformed. In other words, the base metal elements which are in contact with PIN remained intact and are not deformed.

Anyone could help me with this?

Hi everyone,

I'm working on UEL and studying wave propagation in beam. I have a special purpose beam element defined in UEL which has four nodes.  When the beam is horizontal and a vertical load is being applied, it's working perfectly:

Hi everyone,

I am working in UEL. I can get the stiffness matrix from fortran to be printed in .msg file.How can I print the global stiffness matrix of the model by using ABAQUS. My model is not big or complicated, so the global stiffness matrix shouldn't be too big!
Thanks!
