Hi,
I got "Divergence detected in AMG solver" when trying to solve with the exact solution on the domain as follows, it's from paper http://tarjomefa.com/wp-content/uplo...-TarjomeFa.pdf. where Here's the log. Code:

detected in AMG solver: pressure correction I also tried with the taylor green vortex solution (as shown below) with the same settings, and it works. However, I really want to try something non-trivial in the third dimension. I'm wondering whether it's because fluent cannot solve with this solution? Or did I make any mistake? Thanks a lot! |
