How to get the gradient of a scalar in CFX 11.0
 

Can anybody let me know how to get a gradient of a scalar variable using CFX 11.0 without User Fortran

With thanx sm

Dear sm,

You can refer to it, by using the same naming convention you see in CFX-Post..

Examples:

Value = Temperature.Gradient X

Source = Pressure.Gradient Y

Additional Variable = MyOtherAV.Gradient Z

Notice that you always access the gradient components explicitly not the gradient vector..

Hope this helps,

Thanx opaque. Is there a way to get a divergence of a vector in CFX?

Dear SM,

No.. But, what do you want to do with the divergence of vector? Is it a source term in another equation? That determines how you evaluate the term.

You can always (not recommended for source terms) get the gradient and apply the summation of the components:

d/dx + d/dy + d/dz (Phi)..

Thanx opaque. I need it for a source term.
