  • The field “Output path” is a working directory, where new calculations are to be created. If the TCFDSource has been initialized by a TCFD setup file, this field will be already filled with the directory containing the file, or – if such directory is an OpenFOAM case directory – by its parent directory.


  • The field “Directory name” is the name of a new directory containing the next calculation to be done. There are several possible scenarios for this option:
    • If the TCFDSource has been initialized by a TCFD setup file and that file is already inside of an OpenFOAM case directory, then that directory name will be used here making the CFD Processor use the already calculated data and, if needed, overwrite them with new results.


    • If the loaded setup file is not located inside of an OpenFOAM case, then the directory name will be left empty.


    • In any case, the use may decide to specify an own name and press Apply.


  • The button “Write case” will write a new OpenFOAM case into the directory specified by the combination of the above two fields. If no “Directory name” is given, CFD Processor will provide some directory name, which is not yet used in the “Output path”, and put the OpenFOAM case in there. This automatically suggested directory name is always in the form “tcfdcaseX”, where X is lowest non-negative integer available. Note that when “Directory name” is set, then whenever the Apply button is pressed, this “Write case” action will be done automatically.


  • The button “Write + Clean case” will first write the case files corresponding to the current setup and then erase all other files from the case. This is useful when restarting a calculation with different settings. Use it carefully, you may lost old data.
