Mesh transformations and IO

Mesh Reading

The following mesh-formats are supported for reading:

• Gmsh (extension .msh)
• Neutral (extension .neu)
• CGNS (extension .cgns)
• OpenFOAM BlockMesh dictionary files (extension .dict)

Mesh Writing

The following mesh-formats are supported for writing:

• Gmsh (extension .msh)
• Neutral (extension .neu)
• CGNS (extension .cgns)
• Tecplot (extension .plt or .dat)
• VTK-Legacy (extension .vtk)
• VTK-XML (extension .pvtu)

Mesh Generation

Some simple mesh generation capabilities are provided:

• Cartesian Line
• Cartesian Rectangle using quadrilaterals, only uniform
• Cartesian Box using hexahedrals, with grading

A more advanced block-based mesh generation capability is provided

• combine cartesian blocks to form more complex geometries
• with grading

Mesh Transformations

• Growth of overlap in parallel distributed meshes
• Load balancing of parallel distributed meshes
• Accurate interpolation of fields between different meshes
• Initialize a field with analytical functions f(x,y,z)
