CFX5.5 Solver Error
Hi all,
I'd like to ask a error message from CFX 5.5 Solver. For my problem, at the SEVENTH iteration in the solver, there's a error as follows, ERROR #001100279 has occured in subroutine ErrAction. Message" c_fpx_handler: Floating point exception: Overflow Details of error:- Error detected by routine MAKDIR CDRNAM = CopyDs CRESLT = ILEG Details of error:- Error detected by routine POPDIR CRESLT = ILEG Anybody can help me to fix this problem or give me some ideas or suggestions? Thanks in advance! best regards, Sara |
Re: CFX5.5 Solver Error
Hi Sara, the 7th iteration (Time Step), suggests that it may be something to do with the turbulence model. I've had problems where my model would crash on the 7th time step, however not with that error message (as I recall). There are several possible problems, it may be that the solve can't cope when the turbulence kicks in, if so try running for 20 time steps (or longer) with a laminar set up then restart with your turbulence def file. The error could also be due to a incorrtect model setup, eg your solving the thermal energy equations but have an in appropriate Buoyancy reference density set or something like that !! I've found that this is more often the case than the turbulence problem, but I don't want to speak for everyone. Hope this helps ? Bob
