Hi, you can read meshes from various formats, see https://www.dealii.org/developer/doxygen/deal.II/classGridIn.html
W.r.t. adaptive refinement, this is a big area of research and you need to do a literature review to see how people do it in your field. Generally, it boils down to (i) error estimator (ii) marking strategy. For latter see https://www.dealii.org/developer/doxygen/deal.II/namespaceGridRefinement.html#ab5d78628e900af6dc05114f756aa3114. The former is generally problem dependent, but you can start with Kelly error estimator https://www.dealii.org/developer/doxygen/deal.II/classKellyErrorEstimator.html . Regards, Denis.
