import a file and solve a new equation

alimea · January 21, 2017, 04:48

Hi all
I want to solve the equation

laplacian(y)=y0
in openFoam in a rectangular domain that y0 is a velocity distribution { u(x,y) }in this domain and I should import it to this solution.
I saw the probelem of

laplacian(y)=0

in tutorial but I have to change it to laplacian(y)=y0.
How can I do that?
How should I import a u(x,y) as a y0?

Thanks

Quick Answer:
Have a look at the utility "mapFields". It seems to be (partially at least) what you need.
