dvr 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		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!
color_interval	R(2)	0.0, 1.0	Interval of values used for determining the particle color displayed in the animation. See particle_color for further explanation.
dt_dvrp	R	9999999.9	Temporal interval of scenes to be displayed with the dvr software (in s). Isosurfaces, cross sections and particles can be displayed simultaneous. The display of particles requires that the particle transport is switched on (see dt_prel). Objects to be displayed have to be determined with mode_dvrp. If output of scenes created by dvr software is switched on (see mode_dvrp), this parameter can be used to assign the temporal interval at which scenes are to be created (and the respective graphical data is to be output to the streaming server). Reference time is the beginning of the simulation, i.e. output takes place at times t = dt_dvrp, 2*dt_dvrp, 3*dt_dvrp, etc. The actual output times can deviate from these theoretical values (see dt_dopr). Is dt_dvrp < dt, then scenes are created and output after each time step (if this is requested it should be dt_dvrp = 0).
dvrpsize_interval	R(2)	0.0, 1.0	Interval of values used for determining the particle size displayed in the animation. See particle_dvrpsize for further explanation.
dvrp_directory	C*80	'default'	Name of the directory into which data created by the dvr software shall be saved. By default, the directory name is generated from the user name (see package parameter dvrp_username) and the base file name (given as the argument of mrun option -d) as '<user name>/<base file name>' .
dvrp_file	C*80	'default'	Name of the file into which data created by the dvr software shall be output. This parameter can be given a value only in case of dvrp_output = 'local' which determines that the data created by dvr is output to a local file (on the machine where PALM is executed). Apart from the default, it is only allowed to assign '/dev/null' (which means that no output is really stored). This can be used for special runtime measurements of the dvr software.
dvrp_host	C*80	'origin.rvs.uni-hannover.de'	Name of the computer to which data created by the dvr software shall be transferred. In case of dvrp_output = 'rtsp' only the default value is allowed (streaming server of the RRZN). For dvrp_output = 'local' the assigned value is ignored.
dvrp_output	C*10	'rtsp'	Output mode for the dvr software. The following settings are allowed: 'rtsp' Data created by the dvr software is transferred using a special transmission protocol to a so-called streaming server, which is able to continuously transfer visualization data with a high transmission rate. Additionally, with this output mode a set of files is generated automatically within a directory on the streaming server (beside the visualization data e.g. some html-files) which can be used to visualize the data via an internet-browser plugin. Host (streaming-server) and directory can be defined by the user with dvrp_host and dvrp_directory. 'ftp' Data created by the dvr software is transferred to the destination host (see dvrp_host and dvrp_directory) using ftp. 'local' Data created by the dvr software is output locally on a file defined by dvrp_file.
dvrp_password	C*80	'********'	Password for the computer to which data created by the dvr software is to be transferred. Assigning a password is only necessary in case of dvrp_output = 'ftp' . For dvrp_output = 'rtsp' the default value must not be changed!
dvrp_psize	R	0.2 * dx	Diameter that particles are given in visualizations with the dvr software (in m). In case that particles are visualized with the dvr software (see chapter 4.5.7?), their size can be set by parameter dvrp_psize. All particles are displayed with this same size. Alternatively, the particle size can be controlled by certain flow parameters using parameter particle_dvrpsize. Another way to control the particles diameter is to set it with the user-interface in routine user_init_particles (at the beginning of the simulation) and/or to redefine it after each timestep in routine user_particle_attributes. Note: This parameter determines exclusively the size under which particles appear in the dvr visualization. The flow relevant particle radius is determined via the particle parameter radius!
dvrp_username	C*80		User name of a valid account on the computer to which data created by the dvr software is to be transferred. Assigning a value to this parameter is required in case of dvrp_output = 'rtsp' or 'ftp' .
groundplate_color	R(3)	0.0, 0.6, 0.0	Color of the ground plate. The color is given in RGB (red/green/blue) portions. The default color of the ground plate is green.
