 July 1, 2013, 02:29 How to bound fields... #1 New Member   Abhiroop Join Date: Jun 2013 Posts: 26 Rep Power: 4 Hi people......I need your help ,,,its a bit urgent,,,,,,, I have a TEqn defined as -- volScalarField mu1=0.62*1.82*pow(a,2)*g*pow(T,2)*pow(0.68-T,-1); volScalarField mu2=0.41*pow(a,2)*g*T; volScalarField mu3=0.41*pow(a,2)*T*T; Info<< "Solving for T " << nl << endl; solve ( fvm::div(phi, T) //- fvm::laplacian(nu, T) - fvm::laplacian(mu1, T) - fvm::laplacian(mu2, T) == fvc::laplacian(mu3, g) ); My UEqn is--- tmp UEqn ( fvm::div(phi, U) - fvm::laplacian(nu*pow((1-T/0.68),(-1.82)), U) ); UEqn().relax(); fvOptions.constrain(UEqn()); solve(UEqn() == -fvc::grad(p)); So the value of T has to be between 0 and 0.68......How can I do this in OpenFoam..???
