can anybody help how to include a source term which involves the gradient of the scalar using CFX 10 for user defined variable.

thanx

Dear sm,

In ANSYS CFX 10.0, you must use User Fortran to access the gradient of a scalar, and use it as a source term.

The User CEL example number 2 in the User Fortran documentation uses the gradient of an additional variable (scalar) as a source term for the momentum equation.

In ANSYS CFX 11.0, you can do it w/o the User Fortran.

Hope this helps, and your choice of version to use

Thanx opaque, i have found it. I will try to use it

Dear opaque,

Could you let me know how to do without User Fortran in CFX 11.0. I tried with CFX 10 but had some compiler problem.

With thanx
