Hello
I was wondering if there is some detailed documentation on the xml file format for Dolfin that could be used to store data, create facet-functions/mesh-functions, and manipulate meshes.
Mainly, I am working with some complex curved geometries, and I want to extract the boundaries of that domain for applying boundary conditions. It does not seem like the subclassing of SubDomain class, and writing a simple inside function is possible for such generalized curved boundaries. I have on the other hand, the extracted surface meshes for each parts of the boundary, and I wanted to manipulate an xml file to specify perhaps a mesh-function/facet-function to load into the program directly.
There unfortunately is not enough documentation on such xml file formats.
Thanks.
