Fluid Structure Interaction using MFX : ANSYS-CFX

March 1, 2006, 00:37

Hi Everyone

Has anyone simulated fluid structure interection problem e.g. simulation of motion of a ship model in a wave tank, using MFX ? I was able to simulate flow around the shil hull in cfx very well (with out motion).The I thought of trying FSI. I have prepared two model, the ship hull in ansys and the fluid domain in cfx. When I try to start the simulation form ansys launcher (MFX -ANSYS/CFX environment) I get following error ..

/COM,ANSYS RELEASE 10.0 UP20050718 16:41:57 02/28/2006

*** FATAL *** CP = 0.953 TIME= 16:42:05

The database (-db) space requested is not currently available. Reenter ANSYS command line with less database space requested.

encountered the error: -11000.

Can anyone let me know what these errors are? Thanks in advance.

Go to customization/preferences on ansys product launcher window....check the use custom memory settings.....reduce the total workspace & database both....its a trial & error method...for me it worked....for 32 bit windows xp platform make total workspace 400 MB & database 150 MB....i think it will work!!!!!

Hi, everyone.
I´m triying to simulate a FSI using MFX. I obtained next error:
"Quadrilateral elements has negative or zero volume. Nodes on elements must be numbered counterclockwise"
Do you know how i can solve this problem?
Thanks.
Alberto.
