Hi, All
I solved a simple electrostatic problem for computing the potential field (V) in a tube (axisymmetric problem) filled with water. At one end I imposed a voltage of 500V and grounded the other end, one of the wall is defined as axis of symmetry while other has a zero charge/symmetry boundary condition . I calculated the electric forces by writing an expression of the form (f = epsilon*LaplacianV*delV) , however when I am changing the grid density (increasing the mesh density) the value for the electric forces keeps on changing. I am unable to conclude. Is there any other alternative available to calculate the electric forces. I need to calculate them in order to utilize them in Navier-Stokes equations for the CFD part of the problem. I am using version 3.5(a) and I am using mapped meshes.
Thanks
