CFD type changes

[GoogleCodeExporter]

Can we make CFD type changes to cantera while using from Matlab? I tried to do 
that but I am unable to locate the file that does that.

Thanks,
Parth

Can you explain what you mean by "CFD type changes"?

Hello,

By CFD type changes I mean for example: Changes in the timestep, mesh and also 
if its possible to make changes to the finite difference approximation 
equations and if its possible to add terms to it like electric fields? I am 
using the one dimensional non-premixed flame model.

Thank you!
Parth

The implementation of the 1D flame solver is entirely in C++. If you want to 
change the equations being solved, have a look at the method 
AxiStagnFlow::eval, defined in src/oneD/StFlow.cpp.

For the mesh, look at src/oneD/refine.cpp, and for the time stepping, look at 
Sim1D::solve (in src/oneD/sime1D.cpp) and OneDim::timeStep (in 
src/oneD/OneDim.cpp).

Thank you for your response! It really helps but I am unable to find the files 
that you mentioned earlier. Are those present by the same name in the latest 
Cantera Version? I'm sorry but I'm having a hard time locating those- Thanks! 
Please help me.

Sorry for the typo, that should be "Sim1D.cpp" for the location of 
Sim1D::solve. Those files are in the source code for the current release. If 
you aren't compiling Cantera from the source code, then these files won't be 
present and you won't be able to make changes to them.

I may sound a very ignorant here. But how do I compile Cantera from the source 
code? Could you please explain it to me very briefly? I downloaded the latest 
version of cantera and just followed the instructions on the website.

The documentation is here: 
http://cantera.github.com/docs/sphinx/html/compiling.html

If you don't know how to program in C++, then you aren't going to be able to 
make the necessary changes to the source code.

I have a good understanding of C++. I'm just not able to find those files in 
the source code which is really strange to me.
