In the file kEpsilon.C, the source term for momentum equation is defined as:
- fvm::laplacian(muEff(), U) - fvc::div(muEff()*dev2(fvc::grad(U)().T())) But what does dev2() mean? What is the mathematical expression for the term dev2(fvc::grad(U)().T()))? Thanks! |

Hi,
I have a question conserning the operator "dev2". For example I am interested in the following line: fvc::div(muEff()*dev2(fvc::grad(U)().T())) Can someone help me to translate it? Thank you in andvance, Rita |
