GiD_Event_SelectGIDBatFile: must be used to switch the default batch file for special cases.
This procedure must return as a value the alternative pathname of the batch file. For example it is used as a trick to select a different analysis from a list of batch calculation files.

in fact can return a list with the batch_name and some extra arguments to be added to the bat call

Note: The batch_name must be relative to the problemtypes folder, not absolute, and the extra arguments will be added to the four default arguments

proc GiD_Event_SelectGIDBatFile { dir basename } {
    ...body...
    set value ...
    return $value
}

example:

This example maintain the default bat filename to be called, but add the the four default arguments a 5^th extra argument (with the number of threads, specified by the user in the preferences window)

proc GiD_Event_SelectGIDBatFile { project_name basename } { 
    set problemtype_tail [file tail [GiD_Info Project ProblemType]] 
    set filename_bat $problemtype_tail.win.bat
    if { $::tcl_platform(platform) != "windows" } {
        set filename_bat $problemtype_tail.unix.bat
    }
    set ncpus [GiD_Set GID_OMP_NUM_THREADS]
    return [list $filename_bat $ncpus]
}

GiD_Event_BeforeCalculate: will be called a little earlier than GiD_Event_BeforeRunCalculation, e.g. to allow renumber the mesh before write the calculation file and calculate
remote is 0 in case of local calculation, 1 in case or remote (sending to procserverd)

proc GiD_Event_BeforeCalculate { remote } {
    ...body...
    set value ...
    return $value
}

GiD_Event_BeforeRunCalculation: will be called before running the analysis. It receives several arguments:

batfilename: the name of the batch file to be run
basename: the short name model
dir: the full path to the model directory
problemtypedir: the full path to the Problem Types directory
gidexe: the full path to gid
args: an optional list with other arguments

If it returns -cancel- then the calculation is not started.

proc GiD_Event_BeforeRunCalculation { batfilename basename dir problemtypedir gidexe args } {
    ...body...
    set value ...
    return $value
}

GiD_Event_AfterRunCalculation: will be called just after the analysis finishes.
If it returns -cancel-as a value then the window that inform about the finished process will not be opened.
It receives as arguments:
basename: the short name model;
dir: the full path to the model directory;
problemtypedir: the full path to the Problem Types directory;
where: must be local or remote (remote if it was run in a server machine, using ProcServer);
error: returns 1 if an calculation error was detected;
errorfilename: an error filename with some error explanation, or nothing if everything was ok.

proc GiD_Event_AfterRunCalculation { basename dir problemtypedir where error errorfilename } {
    ...body...
    set value ...
    return $value
}
