Hi all
I saw in forces code that shear stress is calculated by: shear stress = - mu*gama in code: -rho()*nu*dev(twoSymm(fvc::grad(U))) what is the minus in this formula? Now I want to calculate forces for viscoelastic fluid. should I write: total shear stress = -tau - mu*gama that tau is polymeric stress. Thanks |
