floating point error
I am calculating cavitation in a servo valve(3d)using RNG turbulence model. After 130 iterations, I got some message as following:
Error: floating point error: invalid number
epsilon equation: tol. 1.#INFe+00 0 1.#INFe+00 1 1.#QNBe+00 2 1.#QNBe+00 . . . . . .
This means epsilon is too big to get the adequate turbulent viscosity? Any suggestion is highly appreciated.
Re: floating point error
check ur boundary conditios carefully.
also lower the values of under relaxation factor and use the coupled implicit solver
hope this will help
