Hello Foamers,

how do I decompose all time steps in a given case folder and not only the start time?
E.g. my case is "case1". The folder already got precalculated time folders /0, /1, ... . Running decomposePar in a terminal will check for the start time written in the controlDict, e.g. "1" and decompose this time to the processeors. Is there any why to get the other times decomposed as well (e.g. "0", "2", ...)?

Usage: decomposePar [OPTIONS]
  -allRegions       operate on all regions in regionProperties
  -case <dir>       specify alternate case directory, default is the cwd
  -cellDist         write cell distribution as a labelList - for use with
                    'manual' decomposition method or as a volScalarField for
  -constant         include the 'constant/' dir in the times list
  -copyUniform      copy any uniform/ directories too
  -fields           use existing geometry decomposition and convert fields only
  -force            remove existing processor*/ subdirs before decomposing the
  -ifRequired       only decompose geometry if the number of domains has changed
  -latestTime       select the latest time
                    do not execute functionObjects
  -noSets           skip decomposing cellSets, faceSets, pointSets
  -noZero           exclude the '0/' dir from the times list, has precedence
                    over the -zeroTime option
  -region <name>    specify alternative mesh region
  -time <ranges>    comma-separated time ranges - eg, ':10,20,40:70,1000:'
