Detailed Description
a small program converting a DGF file into a DGF file
dgf2dgf is a small example program for the DGFWriter. It reads a DGF file into any grid, optionally refining the grid globally. The leaf grid is then written back as a DGF file.
The program's usage is as follows:
./dgf2dgf <dgffile> [refinement level]
While the program may seem completely useless, it has the following usages:
- Convert an interval block into a simplex or cube grid (depending on the grid implementation used).
- Resolve the simplex generator block into a vertex and a simplex block, so that it can be used without triangle or tetgen.
- Construct a refined macro grid, which is very useful when setting up parallel computations with ALUGrid.
The source code of this program also demonstrates the easy use of the DGF parser and the DGFWriter.
