Summary0000480: coded function objects crashes when running in parallel
DescriptionThe solver crashes when a run time control function object (http://www.openfoam.org/version2.0.0/runtime-control.php) is used and the code is running parallel. The error message says:

[1]
[1]
[1] --> FOAM FATAL IO ERROR:
[1] error in IOstream "IOstream" for operation primitiveEntry::readData(const dictionary&, Istream&)
[1]
[1] file: IOstream at line 0.
[1]
[1] From function IOstream::fatalCheck(const char*) const
[1] in file db/IOstreams/IOstreams/IOstream.C at line 114.
[1]
FOAM parallel run exiting
[1]
Steps To ReproduceAdd the following code to the controlDict

functions
(
exampleSnipped
{
 functionObjectLibs ("libutilityFunctionObjects.so");
 type coded;
 redirectType average;
 outputControl timeStep;
 code
 #{
     Info << "Hello, world." << endl;
 #};
}
);

Running the code in serial works.

However, decomposing the grid and running the code in parallel generates the error message instate

Additional InformationAn example of the snipped based on icoFoam has been added.

We're aware of this problem - it is some interaction between the masterOnly reading of dictionaries and on-the-fly compilation of the codedFunctionObject.

As a workaround switch off the 'masterOnly' file reading (set fileModificationChecking to timeStamp instead of timeStampMaster) in the etc/controlDict (or your personal one).

Excellent! Thanks, this works.

The problem is actually in the usage of '#{' ('verbatim string') to delimit the snippet of code. This does not work with the masterOnly reading.

The '#{' code issue will be fixed in the next major release.
