Default CFX Discretization, Solvers

Posts: n/a

does anyone of you know where to find about the numerics used and possible with cfx, e.g discretization, solvers, pressure correction methods...

I have already read through the help with its few pages, but more and more I find out new possibilities like switching between piso and simplec. I've gone through the manual of cfx but have found no word about that.Where can one change the setting?

And last, ansys says that cfx offers a coupled solver, which solves the hydrodynamic equations as a single system. Furthermore they claimed before that pressure-correction leads to high costs. I thought therefore that they don't use pressure correction but calculate the problem in a single system avoiding this pressure corrections. But why do they employ then SIMPLEC?

Cheers Florian

ANSYS CFX (aka CFX-5) does not use SIMPLEC. You may be getting confused with CFX-4.
