Finite Element Method vs Finite Difference Method
Could any one please throw some light on differences between FDM and FEM analysis process.
In my layman term, FDM develops difference equations between grid points in the solution process, so primarily requires rectangular grids. FEM will have shape functions and could have nodes between grid points, so can solve more complex geometry without necessarily requiring rectangular grids. Is this correct ? Are there any other specific differences ?
