Calling RGP variables

Gert-Jan · October 5, 2012, 11:43

Hi everyone,

I want to use variables from RGP tables in CEL. Who knows how to call the variables?

For example, I want to use the surface tension for the calculation of a local Weber number. In the RGP table this variable is listed under SURFTEN. My fluid is called liquid. Then I would expect it to be something like liquid.SURFTEN

But this fails in CFX-Pre...........

Many thanks, Gert-Jan

I think the variable is "Surface Tension Coefficient". Try that name.

Hi Glenn,

Thanks for your prompt reply. But now for the EQMOLFR, i.e. equilibrium mol fraction of a component. I need this in CEL to compare it with the actual mol fraction and then to calculate the source term for masstransfer......

Any clou?

Kind regards, Gert-Jan

All the variables and their names are listed in the CFX Reference manual.
