Error Message: "Problem diverges: Momentum transport equation, variable: X-velocity"
 
Does anybody know about this error message: "Problem diverges: Momentum transport equation, variable: X-velocity" (taken from the Case.fla-file)?
i was calculating a simulation of an FAME-Engine+ mesh but the computer aborts the iteration.
however the residuals RESU, RESV, RESW, RESM, etc. are all below 1.

Which turbulence model do you use?

if u are sure that all the residual values are less than 1, reduce the time step and try again ...

solved the problem, it was quite easy: during the meshing process, a meshing interval was defined by multiple surfaces.
but its not easy, to conclude just from the error message to the cause of the problem...
