Hi,

I'v been using the Abaqus command window to run my jobs without any problems.

Today, however, I suddenly got the following message:

Intel Visual Fortran Compiler 9.1 Build Environment for 32-bit applications - abaqus job=eightchain user=eightchain_Jaumann

The NTVDM CPU has encountered an illegal instruction.

CS:117a IP:0204 OP:63 65 6c 27 3a Choose 'Close' to terminate the application

The header of the message says: 16 bit MS-DOS Subsystem

 Has anyone had a similar problem before???

 Thanks,

Hello everyone.

I need to apply a torsional load to the top face of a cylinder. I try doing this but my analysis doesnt run. I am using Abaqus 6.7 EF-1.

Can anyone help?

Hello,

I am doing a literature search on this topic. Particularly, I am interested in existing devices and techniques that are used in academia and industry to 1) avoid shaft whirl in rotating machinery under perturbed loads (e.g. rotor systems), 2) to come out of whirling mode if shaft starts whirling, 3) other techniques related to stabilizing shafts in general to reduce the resulting vibrations.

Any help would be greatly appreciated.

 Thanks.

What is the appropriate mechanics for understanding the MEMS Suspension tethers?

Hello,

    I am a PhD student in Xi'an, China.

    I am studying  some XFEM related papers, to start coding the method, I thought it would be easier if I go through a code for a basic XFEM problem.

   If anybody who have  the code, please send it to me.

    Thank You. 

Hi,

I am in the process of debugging a UMAT.  In my UMAT code I am currently using write statements to output certain variables to the dat file.  I was wondering if there are any other ways to output data during the execution of a job.  Is it possible to print/plot variables, for example using Matlab (maybe even realtime)?

Also, has anyone experience in accessing the fill files (e.g converting them to ASCII and then use Matlab to look at data?).

Thanks,

Andreas
