 June 10, 2010, 19:33 Electric Field With Space Charge #1 New Member   Xingzhi You Join Date: May 2010 Posts: 7 Rep Power: 9 Hi, I want to solve for a electric field with space charge in it. Say it is 2D, with two plate electrode and known voltage, and the charge density distribution is also known(a function of x,y). With this space charge, the electric field need to be solved by Poisson equation as follows: laplacian(phi)= -rho/e. where phi is the electric potential(Volt), rho is the space charge density(C/M^3), e is the elementary charge(C). I am new to OpenFOAM, could you guys give me some advice on how could I set up the model to solve it. Thanks a lot!!!

The chargedWire tutorial gives an example of the case set-up. You will find the tutorial in /OpenFOAM-1.6/tutorials/electromagnetics/electrostaticFoam/chargedWire.
