Electrodeposition coating film thickness calculating method, recording medium stored with film thickness calculating program and readable by means of computer, and electrodeposition coating film thickness simulation apparatus
A finite element model of the environment of electrodeposit coating is prepared by a simulation method, change of an electric field in an electrolytic cell for the case of electrodeposit coating is simulated, the distribution of currents then flowing through individual parts of a finite element model of a to-be-coated object is obtained, the electric variables of currents flowing through the respective surfaces of the finite elements of the to-be-coated object are obtained and accumulated according to the current distribution, the thickness of an electrodeposition coating film is calculated as h=&Sgr;KFICC.E.&Dgr;t/&rgr; if the cumulative electric variable is higher than a deposition starting electric variable such that a fixed concentration is attained by OH− or H+.
