NekMesh is a utility bundled with Nektar++ which has two purposes:
NekMesh replaces a previous utility called MeshConvert. This change is to reflect the
fact that the program no longer only converts and manipulates meshes but can now also
generate them from a CAD definition. This mesh generator is in a early beta stage of
development and as such is disabled by default. For the time being those not using the beta
mesh generator can use
NekMesh as they would have used MeshConvert, none of the
functionality or methodology has changed.
There is also some limited support for other output formats. We begin by running through a
basic example to show how a mesh can be converted from the widely-used mesh-generator
Gmsh to the XML file format.
COMPRESSED="B64Z-LittleEndian”. To output in ascii format add the module
option “:xml:uncompress” to the .xml file, i.e.
NekMesh file.msh newfile.xml:xml:uncompress
