#1533: checkpoint cctk_delta_time in PUGH -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: major | Milestone: Component: EinsteinToolkit thorn | Version: development version Keywords: IOHDF5Util | -----------------------------------+---------------------------------------- the PUGH driver currently does not checkpoint the stepsize which makes using it with adaptive timestepping hard. Carpet on the other hand checkpoints the stepsize.
The attached patch writes cckt_delta_time into checkpoints. When reading a checkpoint file that does not set the timestep, the user will see level 1 warning that the attribute cctk_delta_time was not found but the code will not abort and will behave as it does right now otherwise (which is to use cctk_delta_time based on the values from parameters/set in basegrid).
