I want to obtain the dot product of "gradient(T)" with "gradient(U)" with fuction object "expressField", Could you pleae give me some suggetions.
HTML Code:
exprField1{ // Mandatory entries type exprField; libs (fieldFunctionObjects); field NewVariable; /// action new; ///autowrite false; ///store true; useNamePrefix true; // Use expression to define total pressure executeControl timeStep; writeControl writeTime; // expression "0.5*(magSqr(U))"; expression "grad(T)*grad(U)"; // dimensions [ Pa ];} It seems there is not "grad" function. |
