Change computational grid
Hi,
I was wondering how could I change the computational grid of the simulator. I'm aware about the decrease on the performance, but I would like to extract some more accurate data for an experiment of mine.
It seems that the size is defined inside the Model2D.java file. If I change it, should it work fine?
And after changing it, how could I compile it?
Thank you very much.

Sorry, I didn't see these issues until today. For conduction simulations and probably radiation simulations, this should be fine. For convection simulations, this is more a problem due to the butterfly effect in transient simulations. A change of grid size will create impacts far greater than a butterfly as you can imagine. So I would say steady problems should be fine, but I am not sure about transient problems. I am curious how other CFD software deals with this.
@charxie: Was there any development regarding this? It is a great simulator for dummies and for learning proposes, since going to more complex CFD can cost a lot (Open FOAM for example).
@joaofl: You might try the energy2d version in the current pull request. This update should be able to properly deal with modified grid resolutions as you intended right at the beginning.
