[petsc-users] fem mesh generation

[Hui Zhang]

Doest petsc has built-in *cartesian* mesh generator for finite elements?
What I want is: inputs the size of a domain, outputs the geometric coordinates
like (0.1, 0.2, 0.3) for each nodes, volume elements like (1,2,...,8),
face elements like (1,2,...,4). 

I saw there is a DMMeshGenerate, but no examples.
