Last change on this file since 4526 was 4518, checked in by suehring, 5 years ago
Diagnostic output: Define arrays over ghost points in order to allow for standard mpi-io treatment. By this modularization of restart-data input is possible with the module interface. Move input of restart data to doq_rrd_local. Enable mpi-io for restart data. Bugfix: add missing restart input of wtheta_av, wq_av, wu_av, and wv_av.
