Is there some free simple Global Circulation Model that can handle tidally locked planets and can be easily compiled and used on a PC computer? It does not have to be very precise, I am interested mostly in demonstration of main features through broad spectrum of input parameters.
I have tried MIT GCM, which I found quite complicated to compile and run, and EdGCM, which is too much focused on climate on Earth and I didn't manage to modify it for other conditions. I have also tried PlaSim, which is perfect (easily compilable and modifiable), but so far it seems rather unstable when used on different conditions for which it was written. (Like tidal locked planet, which it cannot handle at all.)
