<p><P>PROBLEM TO BE SOLVED: To stably obtain an analysis result close to an actual phenomenon by reproducing an actual flow field with fidelity without requiring man-hour of such computation as creating a coarse/fine distribution of mesh models by evaluating an analysis error beforehand. <P>SOLUTION: A model analysis processing unit 12 iteratively computes a parameter for fluid dynamics of each of elements under a preset condition for an analysis space A, determines whether the parameter of each of elements obtained by the iterative computation is converged as predetermined or not and, when it is determined that the parameter of each of elements is converged as predetermined, outputs a result of the iterative computation to a display processing unit 14. In such a case, if a computation result is not converged, in the case where pressure P of each of elements obtained by iterative computation exceeds a preset threshold value Pc, an element having the pressure P exceeding the preset threshold value Pc is identified and separated, a preset resistance value Rmax with which a flow does not enter the separated element is set, and the set resistance value is variably set in accordance with the pressure P by computation repeated thereafter. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
