ktj1993 New Member Kshitij Gupta Join Date: Feb 2019 Location: Mumbai Posts: 2 Rep Power: 0	I am solving Laplace equation which states that second derivative of potential (E) is zero. I am using LaplacianFoam as solver. My geometry is in 2-D. At one patch I have to implement functional boundary condition which is dE/dx = k* [exp ((E-Ec)/a)- exp ((E-Ea)/b) ] where k,Ea,Ec,a and b are constant and I have to solve for E. I am unable to implement the boundary condition. Can anyone help me with implementation. Thanks in advance.
