If I understand you correctly, you want to do a plain average of the fields over the existing time snapshots?

In addition, do you mean that the average results for a dynamic mesh are acceptable for doing

runTime.write()

Code:

for (const_iterator iter = begin(); iter != end(); ++iter)

is replaced by

Code:

forAllConstIter(HashTable<regIOobject*>, *this, iter)

iterator is a built-in pointer of containers, here class objectRegistry inherates from regIOobject and more importantly has access to a table of IOobject.

In the above iteration, iteration is done for all object registried.

In the quoted code, iter() is a pointer pointing to IOobject and it calls writeOpt()...

could not open file for when compiling

Posted March 31, 2017 at 12:46 by kindle

if the problem is :
could not open file ** for xx due to No such file or directory. Maybe it's that after option -I you have a blank space before the INC directory.

Code:

-I$(LIB_USER_SRC)/viscoelasticFluidFoam-1.0-OpenFOAM-2.1.x/src/transportModels/viscoelastic/lnInclude

will do but

Code:

-I $(LIB_USER_SRC)/viscoelasticFluidFoam-1.0-OpenFOAM-2.1.x/src/transportModels/viscoelastic/lnInclude

may not.

Made a copy of the tutorial "lagrangian/DPMFoam/Goldschmidt" and ran the utility blockMesh.
Then I had to look at which file needed to modified. All pointed to the file "constant/kinematicCloudProperties".
Now I had

// 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
