Output subset of cells

I am starting to hit a space/memory boundary since my VTU output becomes > 100 GB. Partial mitigation to this would be to output (DataOut) only some cells in VTU, which are of interest. In my applications, I can easily ignore at least half of cells.

Is there a possibility to do that within the existing interface?

Alexander,

have a look at https://www.dealii.org/developer/doxygen/deal.II/classDataOut.html#afdefbb966f2053f4c4fc52293d2339ce.

You just need to overload DataOut::next_cell().

Best,

Daniel
