Dvrp parameters

Package: (mrun option -r) dvrp_graphics
NAMELIST group name: dvrp_graphics_par

Parameter Name Type Default Value Explanation

clip_dvrp_l

R

0.0

Left boundary of the displayed domain (in m).

This parameter can be used to restrict the display of the total horizontal domain, e.g. to reduce the data size of the dvr-output in order to speed-up the animated sequence.

clip_dvrp_n

R

(ny+1)*dy

North boundary of the displayed domain (in m).

This parameter can be used to restrict the display of the total horizontal domain, e.g. to reduce the data size of the dvr-output in order to speed-up the animated sequence.

clip_dvrp_r

R

(nx+1)*dx

Right boundary of the displayed domain (in m).

This parameter can be used to restrict the display of the total horizontal domain, e.g. to reduce the data size of the dvr-output in order to speed-up the animated sequence.

clip_dvrp_s

R

0.0

South boundary of the displayed domain (in m).

This parameter can be used to restrict the display of the total horizontal domain, e.g. to reduce the data size of the dvr-output in order to speed-up the animated sequence.

cluster_size

I

1

Vertex cluster size for polygon reduction of topography.

This parameter can be used to reduce the number of polygones which form the topography isosurface. In case of large numerical grids (large number of gridpoints) and /or complex topography, cluster_size > 1 may speed up the animation significantly. Disadvantage: buildings may loose their strict rectangular shape.

The allowed range of values is 1 <= cluster_size <= 5.

Warning: The allowed range of values is not checked. Wrong values may lead to unforseen effects or even aborts!

clip_dvrp_l

R

0.0

Left boundary of the displayed domain (in m).

This parameter can be used to restrict the display of the total horizontal domain, e.g. to reduce the data size of the dvr-output in order to speed-up the animated sequence.

Averaging interval for all output of temporally averaged data (in s).

This parameter defines the time interval length for temporally averaged data (vertical profiles, spectra, 2d cross-sections, 3d volume data). By default, data are not subject to temporal averaging. The interval length is limited by the parameter #dt_data_output_av dt_data_output_av. In any case, averaging_interval <= dt_data_output_av must hold.

If an interval is defined, then by default the average is calculated from the data values of all timesteps lying within this interval. The number of time levels entering into the average can be reduced with the parameter dt_averaging_input.

If an averaging interval can not be completed at the end of a run, it will be finished at the beginning of the next restart run. Thus for restart runs, averaging intervals do not necessarily begin at the beginning of the run.

Parameters averaging_interval_pr and averaging_interval_sp can be used to define different averaging intervals for vertical profile data and spectra, respectively. }}}
