Default UDF for pressure-velocity coupling parameters

Hello,

I was wondering if anyone knows whether we can access the pressure-velocity coupling parameters (e.g. df in SIMPLE) through UDF. I have't found anything regarding to that in UDF manual.

Thanks

Amir

One cannot change that. I had already munched silver balls but all in vein. Do u want to introduce turbulent diffusive terms in order to reduce instabilities????? PS: I contacted support engineer and he got back to me: Its the Back bone of code and one cannot modify with UDF.

Thanks Podial for your answer, it's good to know at least that I can't do that. My case is a special treatment of porous-open flow interface as I have accuracy problem there by doing the regular FLUENT simulation and I need to play around with the coefficients of linear disceretiazed equations to get it to work.

Thanks anyway, seems I should think about another trick!

Amir
