PostProcess utility with swakExpression
 

Hello foamers, how are you?

Guys, I'm trying to calculate the liquid and gas superficial velocities using the same function of the image below. as you can see, the calculations are based in swakExpression to do it.

The reference that I got this, used OF2.1.x with swak4Foam.
I'm using OF5x, also with swak4Foam.

However, when I'm using postProcess utility, as required in version 5.x, it seems OF doesn't recognize the old sintax of postProcess, and thus, I'm not getting the information that I want.

Does someone know to update an old sintax of postProcess to a newer version of it?
If doesn't, I would like to know how can I obtain the gas and liquid superficial velocitiesin a twophase flow in another way...

Thanks in advance!!

So guys, does anyone know how to do it, please??!?!:confused:

If somebody knows how to obtain superficial velocities in another way, I will be grateful.
