hi .
what is the syntax of calculated type of primitive boundary field.my case has three coupled equation with 3 variables. i have a relation between two variables (fields) at a particular patch , say x=constant *y. so how to give boundary condition for x and y at that patch. please help me.

If I understand your question, you have 2 equations coupled via a fixedValue boundary condition. Something like this should work for your boundary condition (although I'd be interested to know if there's a better way):
Code:
label wall2 = mesh.boundaryMesh().findPatchID("boundaryWall2"); fixedValueFvPatchScalarField& bufferT = refCast<fixedValueFvPatchScalarField>(T.boundaryField()[wall2]); scalarField& valT = bufferT; forAll (valT, faceI) { valT[faceI] = c.boundaryField()[wall2][faceI]; } For a gradient boundary condition, it's similar (described here: http://www.cfd-online.com/Forums/ope...ed-system.html) |
