Hello!


I gained heat capacity values from some measurements that I did. Now I want to integrate these in Openfoam. The problem is, that there is no polynomial function that would be a good fit. So what I would like to do is just take 50 heat capacity and Temperature values and let Openfoam interpolate the heat capacity from this list.


So, i am pretty new to C++, so I just wanted to ask if somebody could give me some tips on how to get started or if there is already a function that I could adapt to my problem?
