---|
| 2353 | turbulence recycling method of Kataoka and Mizuno (2002) has been |

| 2355 | with a quasi-stationary turbulence state (see <span style="font-family: monospace;">initializing_actions</span> = <span style="font-style: italic;">'read_data_for_recycling'</span>). |
---|
| 2356 | The precursor run may have a smaller domain than the main run, which |

---|
| 2359 | new feature related with the recycling method is that within a job |

| 2361 | allowed to change. Such a change modifies the domain decomposition |
---|
| 2362 | and requires that the PEs within a restart job have to know from which |
---|
| 2363 | file(s) they have to read their restart data (up to now there has been |
---|
| 2364 | a one to one relation between the restart files and the PEs, i.e. |

| 2366 | subdomain index limits of all restart files are now written by PE0 (to |
---|
| 2367 | file "_0000"). Also, all variables containing global values which do |
---|
| 2368 | not depend on the subdomain are written to file "_0000" only. In a |

| 2369 | restart run, this file is opened by all PEs to read these global values |
