Restarting OpenFoam run

gashishr · October 10, 2011, 13:32

Hi,

I am solving an airfoil case for different angles of attack using simpleFoam. I have results for AOA 2deg. I want to solve for an AOA 4deg with results from 2deg as initial values. How can I do that?

try using the mapFields utility between the two cases if they have the same boundary condition names. If the mesh is a different shape (i.e. geometrically non-similar) then I'm not sure how it interpolates to the new mesh and if it can even be used. Its worth a try.

to find the usage, try

Code:

mapFields -help

if they are identical in every way except the number of cells, then it should work. Otherwise you might have to make a mapFieldsDict that is in:

OpenFOAM/OpenFOAM-2.0.x/applications/utilities/preProcessing/mapFields

folder.

cheers,
