General Question about code developing
 

Hi everyone,
I have a general question about OF coding. Considering that I have started a simulation using OF. Then during running this case, I have changed the OF library and compiled it. So does it affect the running case with the previously compiled configuration?
Cheers,
Mohammad

Nobody interested in answering my question?

A general answer to your general question: well, it depends...

Being more pragmatic: In principle it shall not affect your already-running case. Of course, if you stop&resume it the system will make use of the new binaries.

You was so specific indeed. I mean the already-running case. So in your opinion, making a change in library and compiling it doesn't affect that case.

As guin wrote, it depends.
I had systems in which changing a binary used by a simulation was causing the simulation stopping with a "BUS error", while on other systems it did not stop.


However, it's never a good idea...

Got it. Thanks Francesco for your nice reply.

hello everybody
i wonder whether it is possible to run OF codes on a generic compiler (not through the TERMINAL determined by the official releases)?
for example can i run the Cavity tutorial codes on CodeBlocks C++ compiler?
i think if OF is a real open source code it must be possible!
thanks in advance.

Sure, you can choose a different compiler, recompile everything and run the software. Compilation rules are in wmake, they do exist for some compiler (and mpi), might be added for other ones. Configuration files in etc, like bashrc, might need to be adapted as well.

You mean it is possible for example to copy paste OF codes in a generic c++ compiler and run?
If that is! I am really wondered by that.

No, I am not saying that. To be honest, I'm not sure I understood what you mean with that.


What I am saying is that you can use different compilers to recompile the whole OpenFOAM package, including your custom libraries and applications.
OpenFOAM is C++ code, although with a unique code style, but you cannot take just a solver source, it includes headers and imports lots of libraries from the openfoam source directories that must be recompiled as well.
