What is the difference between fromPiAndQtoFneq and fromStrainToFneq

Hi community,

I would like to do some types boundary conditions that are based at fNeq, like Langmuir model, but I have these two questions about the fNeq.

what is the criteria to determine the fNeq from the fromPiAndQtoFneq template or from the fromStrainToFneq template?

And is there a difference in the FNeq accuracy 's at the two methods?

Thanks for your suggestion

Hi,

both are doing the same. One is using the strain rate and the other the second-order moment of the populations.

Orestis, Thanks for your clarification
