<P>PROBLEM TO BE SOLVED: To improve prediction precision of air stagnation while suppressing working costs. <P>SOLUTION: From among a plurality of nodal points constituting a car body analysis model, a nodal point i10 positioning in a terminal is set as a boundary nodal point in contact with an electrodeposition liquid. When determining whether or not an adjacent nodal point i9 adjacent to the boundary nodal point is in contact with the electrodeposition liquid, an air bubble model deposited on a work surface between the nodal points i9 and i10 is set, and a buoyancy component force Fup which becomes parallel with the work surface is calculated from a buoyancy Fu operating on the air bubble model. Continuously, a thrust component force Flp which becomes parallel with the work surface is calculated from a flow thrust Fl of the electrodeposition liquid operating on the air bubble model. Then, a resultant force (Fup+Flp) operating on the air bubble model is calculated from the buoyancy component force Fup and the thrust component force Flp, and it is determined whether or not the resultant force exceeds an adhesive force Fs of the air bubble model deposited on the work surface. In the case where the resultant force exceeds the adhesive force, the air bubble model moves, thereby determining that the adjacent nodal point i9 is in contact with the electrodeposition liquid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
