Hello, I am asking for guidance and/or clarification on how one should best handle changes to the mesh topology within TSSetPreStep of a TSSolve. Out current methodology after making the change is: 1. TSReset(ts); 2. DMSetUp(dm); 3. TSSetSolution(ts, sol); 4. TSSetDM(ts, dm); 5. TSSetUp(ts); I have not found any relevant examples in the documentation so if there is one or an example in another code base, please feel free to direct me towards it. Kind regards, Ross. ________________________________ Ross Williams PhD Research Associate Glasgow Computational Engineering Centre (GCEC) E: [email protected] W: https://urldefense.us/v3/__https://www.gla.ac.uk/schools/engineering/staff/r...
