Hi dear fomers....i want to solve following equation-
ddt(Cp,T)-laplacian(K,T)=S0 where S0=Io*exp(-(x*x+y*y)) where S0 is a laser beam moving with 10 cm/s velocity.Now..i am stuck at how to model this source term??. kindly give your valuable suggestions.... Thanks |

is x the first array of position vector ?
if yes , you can access to position vector in cell center with mesh.C() and in cell face with mesh.Cf() so volVectorField positionVector=mesh.C(); volScalarField x=positionVector.x(); volScalarField y=positionVector.y(); then source term would be forAll (x,celli){ S0=(x[celli]*x[celli]+y[celli]*y[celli]); } i guess some things like above code can help you |
