[deal.II] Output domain id for different parts of the domain

[陈敏]

Dear all

I'm dealing with a fluid-structure interaction problem, and I want ot output the domain id to the cell to the vtk/vtu result files. By the way, partitioning the fluid and solid domain by the id can be very convenient in paraview. But I don't know how to output the domain id when using dealii. Could anyone help me?

Best regards

Chen

Chen,

Have a look at how the subdomain id is added to the output results in
step-40 (https://www.dealii.org/current/doxygen/deal.II/step_40.html#LaplaceProblemoutput_results).

Best,
Daniel
