Improved many‐to‐one sweeping

This paper presents PMOST, the polymorphic many‐to‐one sweep tool. Through its polymorphic design it is able to project nodes quickly and with high quality through ‘modular’ node projection schemes. PMOST currently employs two different node projection schemes: Faceted and BoundaryError node projectors. Implementation details are presented for both of these methods. The proposed many‐to‐one sweep tool was compared to existing software with respect to speed and element quality. Performance testing using PMOST showed that the Faceted node projection scheme was the most efficient while the BoundaryError method produced less element distortion while approximating the efficiency of the Faceted scheme. We also demonstrate improved performance with respect to both element quality and algorithm efficiency when compared to other existing node projection methods.
