Where is the source code for mesh.update()?

Verse · July 12, 2016, 09:17

I'm currently looking for the source code for a file, but have been having some trouble. The specific line is from fluidStructureInterface.C (from foam-extend 3.x), fluidMesh_.update(). The overarching solver itself uses dynamicFvMesh, but I've still been unable to find the respective source code for the .update() member function.

Thank you in advance for the assistance.

Hi,

I've had a quick look at FSI version 4.0.

You were correct to start looking in dynamicfvMesh for update() function.

If you take a look at *.H file, this member function is set as:

Code:

virtual bool update() = 0;

It is an abstract member function, hence it should be defined in all derived classes. I am not sure which derived class is used in your case, so I would suggest taking a look at $FOAM_SRC/dynamicMesh/dynamicFvMesh/. In this folder you can see all of the available derived classes from dynamicFvMesh. As far as I could see they all have a definition of update() member function.

So if you can figure out which runtime selectable dynamicFvMesh model/library is used, then you can look up the algorithm it uses in update() function.

Hope this helps.
Ben

Hi rhythm, thanks for your reply. I actually found what I was looking for in dynamicMotionSolverFvMesh (turns out it depends on what solver you are using). I attached a link to the presentation I referenced if anyone in the future is curious as to how to find it for specific cases.
