The arrangement comprises a mesh dividing part (11), a working condition setting part (12); an interface calculating part (13) for calculating, based on a calculation condition set by the working condition setting part (12), an interface shape change related to a working process; a level value setting part (14) for setting, based on an interface shape calculated by the interface calculating part (13), a level value related to a distance between each of lattice points and the interface; and a level value information storing part (20) for storing the associated level value and interface for each lattice point. This arrangement can express a plurality of material shapes having smaller dimensions than the mesh element size, whereby the mesh element size can be enlarged and the memory consumption amount and the calculation execution rate can be improved.
