Hi,

I am writing a tool with which I would like to be able to write in another case than the one used to launched the tool (To do operations between fields obtained in different cases).

Here is the kind of field I use to write at time directory 2 in another case:

volVectorField UBase
(
IOobject
(
"UBase",
"../channel-base/2",
mesh,
IOobject::NO_READ,
IOobject::NO_WRITE
),
UFirst
);

However, a call to UBase.write() did not produce the creation of the file in the corresponding directory. Is this a restriction, and is there a way to bypass it ?

Note: I have already used "../" in a case name for an IOobject to read data, it works, but writing does not.

Thanks !

JD

Problem solved, there seem to be no problem to use "../" . I was just writing the wrong fields in my test case and got the impression that nothing was done.

Another thing, if the destination directory ("2" in my example) exist, the file is written there, otherwise a zero directory is created and files are wrtten into it. I don't understand this behaviour.

Bit strange usage. Split the ../channel-base/2 into a local (directory, "../channel-base") and an instance (time, "2"). Might still not work though. Or have an additional runTime to point to the other directory like e.g. mapFields.

Hi,

I would like to get rid of the strange usage to get a code similar to mapFields: multiple runTime objects. My problem is different in that the number of cases will only be known at runtime (through command-line argument) and I would like to automatize in a loop calls to the constructors. My first attempt was to use something like this:

Foam::Time * dynRunTime = new Foam::Time[nbCases];

for (label i=1;i<nbCases;i++)
{
dynRunTime[i] = Foam::Time
(
Foam::Time::controlDictName,
args.rootPath(),
args.caseName()
)
}

where args.rootPath() and args.caseName() would have been replaced by apropriate pathnames generated automatically using i as a parameter. This construction is however impossible, because the "new" keyword call the constructors immediately.

Is there a simple way to achieve this ?

I also tried using std::vector
 

I also tried using std::vector with

std::vector<foam::time> dynRuntime;

dynRuntime.push_back(
Foam::Time(
Foam::Time::controlDictName,
args.rootPath(),
args.caseName()
)
);

but only got compilation errors: http://pastebin.com/f4de2fe3

Finally,

using initializers and a fixed size array (having to recompile is not a pb, as the array still provide a benefit for loops further in my code):

Foam::Time dynRunTime[2] = {
Foam::Time
(
Foam::Time::controlDictName,
args.rootPath(),
args.caseName()
),
Foam::Time
(
Foam::Time::controlDictName,
args.rootPath(),
args.caseName()
)
};

I still got compilation error ( http://pastebin.com/f78914746 )

Enough for today... If somebody knowledgeable pass by... please... help...

John, Why don't you try a P
 

John,

Why don't you try a PtrList to store your pointers?

eg, (pseudo-code)

PtrList<foam::time> myTimes(nbCases);

forAll(myTimes, timeI)
{
myTimes.set
(
timeI,
new Time
(
Foam::Time::controlDictName,
rootPath[timeI],
caseName[timeI]
)
);
}
