A high order curvilinear mesh generation(converting) tool, which is named 'GRIDer', is strongly recommended:

For high order numerical solver, such as DG, high order curvilinear mesh is necessary. If 1st straight-edge mesh is used for high resolution method, non-physics flow phenomenon would appears.

A software named 'GRIDer' is found to convert 1st straight-edge mesh into curved-ede mesh for arbitrary cell type, such as triangle, quad, tet, prism, pyramid.

INPUT: CGNS type of 1st straight-edge mesh && IGES CAD geometry model.
OUTPUT: GMSH format of curved mesh.
