The fuzzification of Laplace equation in two dimensions are discussed with curve border. The interval of fuzzy interval can be determined. Finite difference method applied of two different grids using five points, first for initial values and the second to solve Laplace equation numerically.
Keywords: Fuzzy membership function (f.m.f.), cuts, domain with curve border, five points finite difference, interval of confidence, triangular fuzzy number (t.f.n.)
