Class MeshExporter

java.lang.Object
  org.jcae.mesh.xmldata.MeshExporter

Direct Known Subclasses:

MeshExporter.MESH, MeshExporter.POLY, MeshExporter.STL, MeshExporter.UNV, MeshExporter.VTK

public abstract class MeshExporter
extends java.lang.Object

Extract groups from the full mesh and write them to a UNV file. It renumber elements so there ids are from 1 to n. Although it uses the NIO it may not be performant as efficient as a full dump of the mesh to UNV.
