#Error 001100279
Hi all,
I'm doing a cavitation simulation. I checked the mesh which seems ok but during the solver iterations it suddenly stops (at iteration 31) giving this error. Anyone knows the cause? And besides, there's any error index in the software? Thank you in advance! |
You did not include the error message.
And there is no error code list - I wish ANSYS would publish one, it is ridiculous to show very brief error messages with error codes which cannot be looked up. But almost certainly for a cavitation model your simulation has gone numerically unstable, and you need to increase the numerical stability of your model. And additionally, in my experience cavitation models rarely converge steady state. You often need to do a transient run for them to converge. |
Ups sorry!
thanks ghorrocks for your quick response "ERROR #001100279 has occurred in subroutine ErrAction. Floating point exception: Overflow" So you expect a cavitation simulation to not to converge in steady state but to do it in a long enough transient situation? Why? There's any tool which increases numerical stability for the latter case? Thanks a lot, |
This has some tips:
http://www.cfd-online.com/Wiki/Ansys...gence_criteria And the CFX documentation "Obtaining Convergence". And do a search on the forum for numerical stability - been asked many times, I should do a FAQ on it. |
thanks!!!
I'll have a look |
