Developing a solver for OpenFOAM-combustion
 

Hi all,
I am a amateur to OpenFOAM as well as C++.Gone through the User Guide and Programmers guide.And learnt basics of C++.
My next point is to develop a solver related to wood chip combustion.

I am not clear about,steps to start compiling.Running OpenFoam in a virtual machine.
To start compiling do I have to download a C++ compiler first or I can use text editor directly.

Confused,please help.
:mad:

Learn how to compile your own solver by following this tutorial: http://openfoamwiki.net/index.php/Ho...ure_to_icoFoam. Don't just read it, but actually work through it.

Dear Kidess,

Thanks a lot.i went through the link.It solved many problems I had on how to start working in OpenFoam.

icoFoam.C
 

Now I am trying to going in to icoFoam directory and understand the icoFoam.C.

I could not get what is this UEqn.A() and UEqn.H().

Can anybody help me please?

Have a look here http://bit.ly/12gLP8x (or right here)

Thanks.

I found a thread with same question.
http://www.cfd-online.com/Forums/ope...g-development/

.A()
 

Hi All,
I am trying to understand the .A() member function of fvMatrix<Type> class.
checking fvMatrix.C file.(line no 722 onwards)

http://foam.sourceforge.net/docs/cpp/a04763_source.html

Could someone please explain about this.I know that .A() function converts vector to a scalar.But what is the use of this function.Please try to help.

.A()
 

wow,got it.
.A() is for central coefficient,although I did not try to understand fvMatrix.C file.Found it from CFD book.That is what we are getting in discretised equation aP. like as follows(will be different according to the system.)

aP = aW + aE + aS + aN + aB + aT + ∆F

:)
The above mentioned is related.But,if anyone interested in the matter,please go through "Rhie-Chow" interpolation in openFoam.
Thanks.
