HI
I want to simulate the HI
I want to simulate the 2D Burger's equation (modified a little) on a domain ]0,1[ x]0,1[ , all seems to be simple. But I have the problem of telling the solver I want non-uniform boundary conditions (BC) and specify Initial conditions (IC) on the domain. For example: BC: U(0,y)=U(1,y)= C*y ; V(x,0)=V(x,1)=C*x (so The U vel will vary linearly along the y axis while the V vel will vary linearly along the x axis) IC: For the initial condition t=0. I want to tell the solver that the value of U and V (x-vel and y-vel) are function of the position U(x,y) =sin(pi*x)*cos(pi*y) and V(x,y)=f(x,y) for t=0. Can you tell me how to do it in openfoam? thanxs http://www.cfd-online.com/OpenFOAM_D...part/happy.gif |

BC: timeVaryingMappedFixedValuBC: timeVaryingMappedFixedValue. Reads table of values. Interpolates in space (and optionally time). See the pitzDailyExptInlet tutorial
