ControlDict

Generates the OpenFOAM controlDict file that manages simulation execution settings including timing, write control, and solver type.

Type: openFOAM.system.ControlDict

Parameters

Parameter	Type	Description
application	string	Solver name (e.g., simpleFoam, icoFoam, pimpleFoam)
startFrom	string	Start time control (startTime, firstTime, latestTime)
startTime	number	Start time value
stopAt	string	Stop control (endTime, writeNow, noWriteNow, nextWrite)
endTime	number	End time value
deltaT	number	Time step
writeControl	string	Write trigger (timeStep, runTime, adjustableRunTime)
writeInterval	number	Write interval
purgeWrite	integer	Number of write directories to keep (0 = all)
writeFormat	string	Output format (ascii, binary)
writePrecision	integer	Output decimal precision
writeCompression	string	Compression (uncompressed, compressed)
timeFormat	string	Time directory format (general, fixed, scientific)
timePrecision	integer	Time format precision
runTimeModifiable	boolean	Allow runtime modification of settings

Output

Field	Description
Result	The rendered controlDict file content
