I need to calculate the gradient of an additional variable and insert it in another equation as source term.
Is there a simple way to calculate the gradient in the CFX PRE, e.g. using CEL expressions? |

For example you have a created an additional variable named MyAV, you can then access its spatial gradient components as MyAV.Gradient X, MyAV.Gradient Y, MyAV.Gradient Z as needed in your CEL expressions
Hope the above helps, |

Thank you. I found that the CEL expression MyAv.Gradient_x works!
