I want to calculate the conservation equation of Entropy field, in order to find the point of entropy generation (sources of entropy). In order to do that, I need calculate Divergence of entropy transportation field.
Is there any reasonable way to calculate divergence (generally, differentiation operation in vector field) of the field in CFD-Post and CCL/CEL? Is it possible, or it must be done in Solver phase by adding new variables? I really appreciate your comments. |

Have a look in the CFX reference guide for available CEL operations. For instance u.grad x gives you the x gradient of the u velocity field.
