| 4193 | the implementation of topography, this version contains several other |
|---|
| 4194 | improvements. The most important ones are listed here:<br><ul><li>The cloud droplet code has been optimized (it now runs about 100 times faster than before).</li><li>Output of time-averaged 2d/3d data (sections / volume data) is possible.</li><li>Output of 2d-section data averaged along the direction normal to this section can be done.</li><li>The user-interface has been extended in order to allow 2d-/3d-output of user-defined quantities.</li></ul>The kind of topography to be used is controlled by the new initialization parameter <span style="font-family: monospace;">topography</span>. Allowed values are <span style="font-style: italic;">'flat'</span>, <span style="font-style: italic;">'single_building'</span>, and <span style="font-style: italic;">'read_from_file'</span>. The user can define his own special topography setting within the new user-interface routine <span style="font-family: monospace;">user_init_grid</span>. For the single building case, the building (rectangular) size and position can be controlled with parameters <span style="font-family: monospace;">building_height</span>, <span style="font-family: monospace;">building_length_x</span>, <span style="font-family: monospace;">building_length_y</span>, <span style="font-family: monospace;">building_wall_left</span>, and <span style="font-family: monospace;">building_wall_south</span>.<br> |
|---|
| 4195 | <br> |
|---|
| 4196 | The topography code is already optimized (vectorized) for use on the NEC-SX6.<br><br>Output of time-averaged 2d-/3d-data can be enabled by appending the string <span style="font-style: italic;">'_av'</span> to the respective output quantities given with the new runtime-parameter <span style="font-family: monospace;">data_output</span> |
|---|
| 4197 | (see further below for the (name)changes in the parameters for data |
|---|
| 4198 | output). Example: if a time-average of the vertical cross-section of |
|---|
| 4199 | potential temperature is required, the user has to set <span style="font-family: monospace;">data_output</span> = <span style="font-style: italic;">'pt_xy_av'</span>. |
|---|
| 4200 | In case of NetCDF-output, the time-averaged data is output to |
|---|
| 4201 | additional files (seperate from the non-averaged output). The length of |
|---|
| 4202 | the averaging interval and the temporal distance of the single |
|---|
| 4203 | instantaneous sections (volumes) entering into this averaging is |
|---|
| 4204 | controlled by the new runtime-parameters <span style="font-family: monospace;">averaging_interval</span>and <span style="font-family: monospace;">dt_averaging_input</span>. <br><br>An average normal to the direction of a cross-section can be output by setting the respective cross section index to <span style="font-style: italic;">-1</span> (example: <span style="font-family: monospace;">section_xz</span> = <span style="font-style: italic;">-1</span>).<br><br>New user-interface routines allowing the output of user-defined quantities are <span style="font-family: monospace;">user_check_data_output</span>, <span style="font-family: monospace;">user_define_netcdf_grid</span>, <span style="font-family: monospace;">user_data_output_2d</span>, <span style="font-family: monospace;">user_data_output_3d</span>, and <span style="font-family: monospace;">user_3d_data_averaging</span>. These quantities can be calculated using the new <span style="font-family: monospace;">CASE</span>-Entry <span style="font-style: italic;">'after integration'</span> in the user-interface routine <span style="font-family: monospace;">user_actions</span>.<br><br>Optimization |
|---|
| 4205 | of the cloud droplet code is mainly done by re-sorting all particles |
|---|
| 4206 | after every timestep in a way that now all particles which belong to |
|---|
| 4207 | the same grid-box (k,j,i) are stored consecutively (wthout any strides) |
|---|
| 4208 | in memory.<br> |

|---|
| 4211 | conservation of the volume flow (through the complete xz- and |
|---|

|---|
| 4214 | </li><li>By default, NetCDF output is now using 64-bit offset format |

|---|
| 4445 | kleinen |
|---|
| 4446 | Buchstaben kenntlich gemacht, größere Änderungen durch |
|---|
| 4447 | die Zahl hinter dem Punkt. Eine Inkrementierung der Zahl vor dem Punkt |

|---|
| 4456 | zu entfernen und beim check-in - Kommando als Log-Text anzugeben. Sie |
|---|
| 4457 | erscheinen |
|---|
| 4458 | dann in der jeweiligen Datei unter "Fruehere Aenderungen" zusammen mit |
|---|
| 4459 | der vom RCS-System vergebenen Versionsnummer (dafür sorgt die |

| 4477 | <p>Dieser Abschnitt verweist auf vorhandene Beschreibungen der genauen |
|---|
| 4478 | Funktionsweise einzelner, spezieller Modellteile. Dazu gehört z.B. |
|---|
| 4479 | die Beschreibung bestimmter numerischer Verfahren (auch ihr |

|---|
| 4481 | Hintergrund), die Erklärung besonderer Prinzipien bei der |

|---|
| 4483 | oder Erläuterungen zur Vorgehensweise bei der Lösung |
|---|
| 4484 | bestimmter |
