 July 9, 2012, 06:55 Possibility to transport a Matrix? #1 Member   Hai Yu Join Date: Mar 2009 Location: Harbin Posts: 67 Rep Power: 9 Dear Friends, I want to introduct a new 3x3 elements variable Matrix into pimpleFoam or pisoFoam by transport equation. (noncoupled) the basis equation is (in reality it is more complex): ddt(S) +(U.grad)S =f1(grad(U).S+S.grad(U)) in the equation, S is the 3x3 element matrix. Is it possible? Thanks!

I haven't used it yet, but have you tried volTensorField or volSymmTensorField? Typedef, given in src » finiteVolume » fields » volFields » volFieldsFwd.H: typedef GeometricField volSymmTensorField; typedef GeometricField volTensorField; And detailed description of available operations with tensors and symmTensors is given in ProgrammersGuide at p. 15 and below (you can easily google and download it).

Yep. Tensor is the way to go. And yes: it works. Some turbulence models rely on transporting tensors
