coding solver with C++/python

TurbJet · August 1, 2018, 04:12

Greetings,

A general question here.

Sometimes I see some people saying that they are using both C++ and python for their own solver. I can totally see C++ as their main coding language considering it's efficiency and all. However I don't see why they mix python into it. What makes python useful in this business? And what for?

Thx !

Without further details one can only guess it is either used for the GUI or general solver management via scripting

Could you give some further details about the second point you raised? I mean the scripting thing

Consider this example:

https://openfoamwiki.net/index.php/Contrib/PyFoam

However, I'm just guessing here, you should ask to whom said that

I just skimmed through this webpage. What I get is Python is mainly used for data manipulation and some other stuff. So is it safe to say python is good for being an "interface"? If so, what makes python good at this?

Still "personal opinion" territory, but I guess it is because it is an open source, scripted language with a lot of useful open source libraries.
