// access to field<Type>

Ex: in /finiteVolume/fields/fvPatchField/derived/turbulentInlet.C.
This class is templated, here we take a example for vector field:

Code:
Field<vector> randomField(this->size());
to have access to x-component for example
Code:
Info << "randomField = " << randomField.component(vector::X) <<
    endl;
// vector::X=0 this enum equals to 0 as enum's

typo error

Posted February 23, 2017 at 06:03 by kindle

Q : Get very nasty output in the log when running in parallel ?
A : may be forgot the "-parallel" flag on the command line.
E : In stead of
Code:
mpirun -np 16 icoFoam -parallel > log
you trust your memory and write
Code:
mpirun -np 16 icoFoam > log
Then you will directly get the time directories of the whole domaine and there will be no time directionary in processor*. And in log, it seems that multiple processes are writing at the same time....

I'm trying to program a solver and its need a volscalarfield that initially must be zero everywhere in the mesh and I don't want to read it from any initial condition or to write it down. Anyone know how to do it?
