Calculating Peclet Number in laminar flow when using icoFoam

focus111 · January 29, 2019, 09:51

Dear Foamers,

I'm struggling to complete a simple task (I think): calculating the Peclet number filed on the results of an icoFoam simulation.
When I run

Code:

postProcess -noZero -func PecletNo

It gives an error saying that it needs a turbulence model to complete the calculation.
I'm currently running OpenFOAM 4.0

I hope I'm not missing something really obvious/simple.

Cheers

To write the surface scalar field of Peclet Number (Pe), we need to run the post process utility with solver name.

an example of the command is given below with simpleFoam solver.

Hope this will solve your problem!!!

Regards,
Shadab

Code:

simpleFoam -postProcess -func PecletNo
