<p><P>PROBLEM TO BE SOLVED: To automatically mesh a rectangular parallelepiped block having a restricted surface. <P>SOLUTION: If a target block has a restricted surface for which nodes and connecting lines have been set, the nodes on the restricted surface and the nodes of each angle are connected on the block while a connection pattern for the restricted surface is maintained, so as to simply mesh the target block with a tetrahedral element. If the target block has no angle contacting the restricted surface, one or several nodes are precedingly implemented and the target block is simply meshed through the node(s). Then, rectangular parallelepipeds are attached for coating on surface areas except for the restricted surface of the target block, so as to generate a super box of a rectangular parallelepiped shape. Before and after the attachment, the rectangular parallelepipeds to be attached are meshed so as to cause the nodes and connecting lines on a contact surface with the target block to match those of the block. Nodes that are not set are set in the super box and the target block is meshed in detail on the basis of the Delaunay method. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
