broken restarts on GPUs? #34

Closed glesur closed 1 year ago

glesur commented 3 years ago

It seems like restarts with MHD on GPU with a streteched grid leads to inconsistent divB. The divB appears to be inconsistent at the location where the stretched grid matches the uniform grid. Bug is visible on ipag-gpu1/run/AmbipolarWindCylindrical
