A 2D variational mesh adaption approach is presented for problems in multiphysics. The mesh is adapted by local subdivision controlled by an energy criterion that serves as an error indicator. Thermal and thermo-mechanical problems are studied here through different test cases to test the algo- rithm. Then, parametric analyses are carried out, that is the effect of different parameters of our algorithm is studied for mesh adaption.
