Memory increase during regridding

[Wolfgang Kastaun]

I still have the problem that my BNS runs consume increasing memory during inspiral, where regridding happens. It limits the runtime of typical BNS runs to around 1 day, then they are killed by memory exhaustion. After merger, with fixed grid structure, the problem goes away. It happens with two different codes, WhiskyThermal+McLachlan and WhiskyMHD+McLachlan, on all clusters I use (hydra, marconi, supermuc, fermi, ..), and all releases I used: Payne, Brahe, Tesla, Wheeler. Regridding controled using CarpetRegrid2.

Wolfgang, can you identify a small par file for me which illustrates the problem?
