Peclet number does not appear in ParaView
Hello Foamers!

I ran an icoFoam case and afterwards the Pe tool. I wanted to visualize Pe in ParaView I notice that I have no access to fields. I would like to see them, what do I do?

Cheers in advance

hi claus,

i think you can only see Pe as Vector arrows. To do this you have to type

foamToVTK -surfaceFields

then start paraview and open VTK/surcfaceFields, then "Apply" and Filters/Common/Glyph or simply click the "Glyph" button, after this you can see the vectors of Pe...

i hope this helps

Hello marcbest,

thanks for you advice which had worked, but this way is unsatisfactory, because such an effort must be made. I keep looking for an better solution; probaly the code has to be rewritten.

why don't you try to add peclet number in creatFields.H? as a variable which it shouldn't be read but it should be write ????

what you mean by that? Do you mean to cope the problem by using volScalarField? Currently, I am trying either, but the problem is: I do not know how to compute the measure of the cells, i.e.

Let U, nu and nut be given then

volScalarField Pe

What can I insert for "What"?

Additionally, I should mention that I am only interesting in Navier-Stokes convection-dominated flows.

hi friend
one way can be to enter characteristic length, through Dic by "readScalar" function
then put this length instead of "what" but im not sure!!!

You may have a look at the Co utility, it outputs a volScalarField from a surfaceScarlarField. This could be adapted to the Pe utility
