source: palm/tags/release-3.7a/DOC/tec/technical_documentation.html @ 483

Last change on this file since 483 was 482, checked in by raasch, 13 years ago

New:
---
compare_palm_logs is additionally compiled with mbuild -u (Makefile in trunk/UTIL)

make options (mopts) to be set by configuration file implemented (mrun, mbuild)

humidity=.T. is now usable for runs with topography. wall_humidityflux and
wall_scalarflux are the corresponding new parin arrays.
(check_parameters, init_3d_model, parin)

Large scale vertical motion (subsidence/ascent) can be applied to the
prognostic equation for the potential temperature. (check_parameters, header,
Makefile, modules, parin, prognostic_equations, read_var_list, subsidence,
write_var_list)

A simple method for installing and running palm (with limited features)
has been added. (Makefile, palm_simple_install, palm_simple_run)

Changed:


2d-decomposition is default for Cray-XT machines (init_pegrid)

var_ts is replaced by dots_max (modules,init_3d_model)

Every cloud droplet has now an own weighting factor and can be deleted due to
collisions. Condensation and collision of cloud droplets are adjusted
accordingly. (advec_particles)

Collision efficiency for large cloud droplets has changed according to table of
Rogers and Yau. (collision_efficiency)

Errors:


Bugfix for generating serial jobs (subjob)

Bugfix: index problem concerning gradient_level indices removed (header)

Dimension of array stat in cascade change to prevent type problems with
mpi2 libraries (poisfft_hybrid)

Loop was split to make runs reproducible when using ifort compiler.
(disturb_field)

Bugfix: exchange of ghost points for prho included (time_integration)

Bugfix: calculation of time-averaged surface heatfluxes (sum_up_3d_data)

Bugfix: calculation of precipitation_rate (calc_precipitation)

Bugfix: initial data assignments to some dvrp arrays changed due to error
messages from gfortran compiler (modules)

Bugfix: calculation of cloud droplet velocity (advec_particles)

Bugfix: transfer of particles at south/left edge (advec_particles)

Bugfix: calculation of collision_efficiency (collision_efficiency)

Bugfix: initialisation of var_mod (subsidence)

666release contains further additions, changes, and bugfixes for the
667SGI-ICE system, as well as important changes like the splitting of the
668user-interface into single files, a complete revision of the
669pre-compiling mechanism allowing to use different make-depositories
670simultaneously, and a revision of the reading-mechanism from restart
671files, which has no more restrictions in case that the previous and
672current run have different domain/subdomain sizes. A new handling of
673all kind of output messages is introduced with this release and will be
674applied to all existing messages within the next releases.<br>

751completely revised: the source-tarfile remains in the source directory (<span style="font-family: Courier New,Courier,monospace;">trunk/SOURCE</span>).
752One depository per block (given in the config-file) is created. Always
753all files from the source directory are copied to the respective
754depository. No additional file checks are done any more (mrun version
7552.1). The depository name used contains the conditions given by <span style="font-family: Courier New,Courier,monospace;">mrun</span>-option
