CONNECTING METHOD FOR IMPROPER MESHES OF FINITE ELEMENT LAW ANALYTIC MODEL

摘要

PROBLEM TO BE SOLVED: To easily assemble an analytic model by connecting improper meshes of the optionally mesh-generated finite element law analytic model in a short time. ;SOLUTION: A surface of a model A1 to be connected is brought into contact with a model B2 (step 11) to form a contact surface C. A group D of surface elements overlapping with this contact surface C is extracted (step 12). Then the contacts at the shortest distance among respective contacts of the contact surface C and nodes of the surface element group D are connected and regarded as a segment group (i) (step 13). A closed loop is generated (step 14) from one side of the outer segment of the contact surface C, the segment group (i), and the outer line of the surface element group D, and a closed loop group and the contact surface C are registered as a surface element group E (step 15). Here, when the model B2 is solid (step 16), a solid element group generated by sweeping up to an opposite surface is registered (step 17) and the surface element group D is deleted lastly (step 18).;COPYRIGHT: (C)1997,JPO
