In addition to the elements on either side of the short edge, elements that use one of the nodes of the short edge may also be affected. A tria element along the short edge will typically be deleted. Typically, a quad element along the short edge will become a tria. To create replacement patterns, the short edge is collapsed to a node. If an edge of the resulting pattern is still too small, however, replacement patterns may be created. These embodiments involve a computing device configured for receiving a finite element mesh in electronic format, for receiving input specifying at least one quality threshold value for two or more element quality parameters, calculating a quality score for at least one element within the finite element mesh to identify at least one element whose quality score does not meet the quality threshold values for the two or more element quality parameters, creating at least one substitute element for the at least one element whose quality score does not meet the quality threshold values, calculating a quality score for each of the substitute elements and, if any of the substitute elements have a better quality score than the elements whose quality score does not meet the quality threshold values, replacing elements whose quality score does not meet the quality threshold value with the substitute element(s) having the best quality score.
Other embodiments of the present invention include a computer-implemented method and system for replacing certain elements in a finite element mesh to improve the quality of the mesh.
