hi guys i'm new in cfd simulations.. i'm going to simulate a port flow but when i run the solver i got this error. i'm trying to understand this problem but i didnt' manage in it.

could anyone help me ??

Hi Gio,

Have you checked if you have a file called "transportProperties" in your "constant" folder??

If so, it is readable? (I mean, can u open it without problems)

hi alex. i've made a mistake. the solver to use is not sympleFoam but rhoSimpleFoam.
anyway i cancel this thread and open a new one since i still have errors.
thanks
