I'd like to know which is the meaning of this message:

Error:>(greater than) :invalid argument[2] : wrong type [not a number] Error object: nan

Every suggestion will be appreciated...

Thanks in advance.

I don't know the exact meaning of the error message.

I get a similar error when solving an UDS which made the momentum equation diverge. Try to check the detailed convergence informations (Solve -> Controls -> Multigrid) to see what happens to each equation during iterations.

Hi

ap

I've defined an UDS in my model too, and maybe this is the reason of my error message. Thank you very much for your suggestion!!! I'm going to try it.
