ABSTRACT:
In a finite element meshing model, the number of elements sharing boundaries surrounding a node of interest are counted and whether the node is positioned inside or outside an outer circumference of the element mesh model is determined to detect errors. Errors are detected when the position of a node determined from the sum of the angles of the elements surrounding the node differs from the position of the node determined from boundary face connections. An error is also determined from the maximum and minimum angles of the external shape of a model formed from input data.
