Last change on this file since 759 was 759, checked in by raasch, 11 years ago

New:
---

The number of parallel I/O operations can be limited with new mrun-option -w.
(advec_particles, data_output_2d, data_output_3d, header, init_grid, init_pegrid, init_3d_model, modules, palm, parin, write_3d_binary)

Changed:


mrun option -T is obligatory

Errors:


Bugfix: No zero assignments to volume_flow_initial and volume_flow_area in
case of normal restart runs. (init_3d_model)

initialization of u_0, v_0. This is just to avoid access of uninitialized
memory in exchange_horiz_2d, which causes respective error messages
when the Intel thread checker (inspector) is used. (production_e)

Bugfix for ts limitation (prandtl_fluxes)
