1953 | kind of topography to be used is controlled by the new initialization |

1955 | Allowed values are <span style="font-style: italic;">'flat'</span>, |

1960 | For the single building case, the building (rectangular) size |

1975 | In case of NetCDF-output, the time-averaged data is output to |

1976 | additional files (seperate from the non-averaged output). The length of |

1977 | the averaging interval and the temporal distance of the single |

1994 | of the cloud droplet code is mainly done by re-sorting all particles |

2443 | <p>Dieser Abschnitt verweist auf vorhandene Beschreibungen der |
---|
2444 | genauen |
---|
2445 | Funktionsweise einzelner, spezieller Modellteile. Dazu gehört |
---|
2446 | z.B. |
---|
2447 | die Beschreibung bestimmter numerischer Verfahren (auch ihr |
---|
2448 | theoretischer |
---|
2449 | Hintergrund), die Erklärung besonderer Prinzipien bei der |
---|
2450 | Parallelisierung |
---|
2451 | oder Erläuterungen zur Vorgehensweise bei der Lösung |
---|
2452 | bestimmter |
---|
2453 | Aufgaben (z.B. der Berechnung horizontal gemittelter |
---|
2454 | Größen). |
---|
2455 | <br>Die Beschreibungen liegen in jeweils getrennten Dokumenten, |
