Problem in defining and using the deformation rate tensorHi Foamers,
I am tying to represent the deformation rate tensor in OpenFoam. I know that some instalations use the following code, in the form: DU=fvc::grad(U); DUT=DU.T(); DR=DUT+DUT.T(); I know that other forms work just fine. However, when I solve the momentum equations, that include a term in the form constant*DR, why can not I write the following expression: constant*(fvc::grad(U)+fvc::grad(U).T()). Also, when I do DU.T() above, that is equivalent to do the fvc of the transpose of DU, he gradient of the velocities, right? Your sincerely, António Martins |
