Hi, All: I am working on a fluid structure interaction problem with Smoothed Particle Hydrodynamics (SPH) method in Abaqus. My solid is a deformable structure. I would like to know the pressure on...

If you have the Intel FORTRAN 11, you should be able to download older version from Intel website.

Hi, Jorgen: Thank you for your comments! My simulation has large motion in the beginning, then parts will contact with each other, so it is difficult to tell where the contact will happen. I can only...

I guess Jorgen is talking about Abaqus 6.11. It is released now, but we don't have the media yet.

Yes, it is just a text file, you can write your umat code and then run your simulation with your code.

I am working on nonlinear static contact problem with large motion, but it is unstable even if I use automatic stabilization in Abaqus 6.10. I tried to specify the damping factor directly, but it...

If you need to use mooney-rivlin model, then I think it is better to use the built-in model with NLGEOM on. Could you post some more details if you use *HYPERELASTIC with *BIAXIAL TEST DATA?

If you want to work with Fortran umat, you don't need VC++. You need to install Intel Visual Fortran 10.1 or Intel Visual Fortran 11.1. Are you sure you are using the right installation file for your...

You must right, because I have never done that on Windows.

Go to start -> Abaqus 6.10 -> Abaqus Command, then submit your job.

Another way to do it is use the full abaqus path.

You need to save this code to a file like code.f. Then when you submit your simulation, you need to specific the name the code in the command line by "user = code.f ".

What do you mean by "you didn't make it"? What is the error message you got from abaqus?

To run abaqus with umat, you need define a USER MATERIAL in the input file. Then when you submit your job, you need use user=code file name.f to specify the name of the file which have the umat you...

As far as I know, you can measure or assume the fiber orientation in the tissue. Holzapfel has many papers talking about that: http://www.biomech.tugraz.at/publications

I don't think your step 1 and 2 are necessary, you only need those files. you can get them by unzipping the installation package (.exe file).

Abaqus is stopping suport 32-bit linux veriosn. if you would like to use abqus on linux, you need to choose 64-bit linux veriosn.

You cannot run Abaqus in this way, you have to install Abaqus in a shared directory to run it in compute nodes. Becauce your Abaqus has only been installed on the head node. Once you log on to...

Hi, Jorgen:

I wonder if there is a way to use .obj file instead of .f or .for file when you are running the simulation. I think if you have a lot of simulations to run, and those simulatins are...

I guess you are runing this installation remotely, it seems you didn't setup a X-window well. Can you try to open "firefox" to see if your X-window is working. If not, then that is the problem of...

Jorgen:

It is dispointed to hear this news, I use ABAQUS on many platfrom, we have 64-bit linux version on HPC, I have Abaqus 32-bit Windows version on my office computer and 32-bit linux verion...

Jorgen: you know what, I had this problem too. I was trying to install ABAQUS V6.9-1 in Win 7, it said something like my system was not supported, so I have on idea what to do, then I remembered how...
