PROBLEM TO BE SOLVED: To make executable a procedure for positively finding respective variables according to a specific expression with high calculating capability by executing the procedure or every time step. SOLUTION: The total Fpress of forces operating on unit volumes at respective positions of a substance accompanying the volume variation is composed of a term Fpress eternal of durability developed in proportion to variation in occupation volume per unit substance and a component Fshare of F accompanying shearing stress is composed of a variable Fshare transient reducing the spatial 2nd-floor differentiation of a speed while storing it. Further, the procedure which consists of equations Fpress = Fpress eternal, Fshare = Fshare transient, dFpress eternal/dt = k.grad(div(V)), and dFshare transient/dt = (μ.ΔV-Fshare transient)/τand positively finds the respective variables according to those equations is carried out for every time step.
