Hi,

I have some question about a few lines of the Class Time constructor.

1.

397* libs_(),  //dlLibraryTable libs_; //- Any loaded dynamic libraries. Make sure 
                                                   //to construct before reading controlDict.         
398*             //operator () : T& operator() (const Key& key) inline   
                   //Find and return a hashedEntry, create it null if not present.
                   //template<class T, class Key, class Hash>
                   //inline T& Foam::HashTable<T, Key, Hash>::operator()(const Key& key)
                   //{
                   //iterator iter = this->find(key);
                   //if (iter == this->end())
                   //  {
                   //this->insert(key, T());
                   //return *find(key);
                   //   }
                   //else
                   // {
                   //return *iter;
                   // }
                   //}

First of all, have I found the right overloaded operator () ? If yes, what does the happen here?

2.

417* writeControl_(wcTimeStep),

with

//enum writeControls
       //wcTimeStep
       //wcRunTime
       //wcAdjustableRunTime*
       //wcClockTime*
       //wcCpuTime

What do the the single options in the enum mean?

3.

418* writeInterval_(GREAT),  //scalar writeInterval_;, GREAT ?

What is the variable GREAT and where to find it?

4.

420* secondaryWriteInterval_(labelMax/10.0),    //scalar secondaryWriteInterval_;

What is the variable labelMax and where to find it?

Greetings maybee,

Given the range of questions you've been asking, I suggest that you read and study the following:

• C++: http://www.cplusplus.com/doc/tutorial/
• OpenFOAM User Guide: http://www.openfoam.org/docs/user/
• OpenFOAM Programmer's Guide: http://foam.sourceforge.net/docs/Gui...mmersGuide.pdf
  • Community errata: http://openfoamwiki.net/index.php/Op...s_Guide_Errata
• Community wiki based guide: http://openfoamwiki.net/index.php/OpenFOAM_guide

And you can use Google to help you search for things, for example:

site:foam.sourceforge.net/docs/cpp/ labelMax

And on Github you can also search for things in OpenFOAM's source code: https://github.com/OpenFOAM/OpenFOAM-2.2.x/ - the search bar is on the top of the page.

Good luck! Best regards,
Bruno

Hi,

first of all thanks for the links. Surely I'll read the programmers guide at some point and the forum and github link could come in handy, too.

Furthermore I know a lot about the basics of c++ programming, google really does not help me with my questions and I just can't find the descriptions I am searching for (see QUestion 2,3,4).

• #2 - User Guide, section 4.3 "Time and data input/output control": http://www.openfoam.org/docs/user/controlDict.php
• #3 - Github search for:
  

  #define GREAT

  https://github.com/OpenFOAM/OpenFOAM...REAT&type=Code
  • Lead to this: https://github.com/OpenFOAM/OpenFOAM...r/scalar.H#L52
  • The reason for looking with "#define", was because in C/C++, variable names with all caps probably means that we're dealing with a macro definition.
• #4 - Try using Github search as well
  https://github.com/OpenFOAM/OpenFOAM...lMax&type=Code

Mmm... well, Google can help find things in some other situations, but I guess that Github would be better for finding code definitions in OpenFOAM's code.

Best regards,
Bruno
