ANSYS Workbench Simulation Solver Error

[ajskdlf]

Hi,

Here's the jist of the problem:
I modelled a solid O-ring. I fixed one face and applied pressure on another face. I clicked Solve, and it gave me an error. The window gave the message: "An Error Occurred While Starting the ANSYS Solver Module" and told me to check the ANSYS troubleshooting section in the manual. The manual suggests that I increase my virtual memory or move the temporary files to a new space where I will have enough disk space.
The thing is, I already have my virtual memory set at 8GB and my computer specs are as follows:

-2GB RamCPU Intel Core 2 Duo Conroe E6400 2.13GHz FSB 1066, 2MB CPU
-Memory 2048MB DDR II 667 Memory 240 Pin (1024 x 2)
-Motherboard ASUS P5N SLI Motherboard
-Western Digital 250GB 7200RPM 8MB Cache Serial ATA II
-(2x)SLI Video eVGA GeForce 7900 GS PCI-E 256MB DDR3 DVI. HDTV

It's a gaming rig and I am pretty sure I have more than enough to run/store the files. All my ANSYS workbench settings are at default. Any help would be appreciated. Thanks.

Have you tried using a different solver setting. Try setting it do iterative perhaps?

 

[ajskdlf]

Still received the same error message. But thanks for the suggestion.

Hmmmm that'd odd. How many DOF's is your model? If you're modeling an o-ring why don't you make it axisymmetric? Your run time and file sizes will be many times smaller.

I stated an o-ring just to simplify the question. It's the shape of an 'o' but there are modifications to it. I've set it at 6 DOF.
I've asked a friend to run it on his laptop, and it runs perfectly fine with a run-time of about 1 min. And his laptop specs are not as good as my desktops'.
I'm thinking it might be one of those setting issues, but I'm not sure which one it is.

ajskdlf,

Can you run any of the Ansys test/demo jobs on your machine ? Maybe the error is not specific to your o-ring problem.

I can model parts with no problems, but when I modelled a solid cube or imported some part drawings from CATIA and tried to do some of the simulation tests (i.e. with a simple clamp + force), it still gave me the same errors.

When I try to generate a volume mesh in CFX on a simple part drawn in DesignModeler, it gives me 4 errors. They're stated as follows:

1) The location F1604.2024,F1605.2024, etc... refers to # primitive regions that do not appear in the geometry. These regions are: F1621.2024, F1847.2024, etc...

2) There was a problem processing the location of the face spacing
Default Face Spacing

3)Because of the problems with the face spacing "Default Face Spacing"
it is being ignored.

4)Unable to identify the default body spacing "Default Face Spacing" referred to
in the "Default Face Spacing" parameter of the "Default/SPACING" spacing object.

So only my Designmodeler works. Simulation & CFX does not. Is it my settings?
