We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Are you writing/reading both case and data files each time? Since you are using Dynamic Mesh, your mesh will change over the course of the simulation. Mesh information and position is saved with the .cas file, so if you only load the .dat file onto a case that does not correspond to it, your solution and mesh position might not match exactly at the first few time steps.
