The discussion centers on modeling hexagonal ice Ih using C++. Participants express the need for clarity regarding the specific modeling goals, particularly in relation to properties to be calculated or visualized. Recommendations for resources include Jensen's "Introduction to Computational Chemistry" for foundational knowledge. One user has made progress by creating an 8-molecule unit cell using C++ and OpenGL but seeks advice on producing proton-disordered ice and expanding the model to larger unit cells, ideally 5x5x5 or more. There is a call for assistance with implementing algorithms for proton disordering, highlighting a gap in programming skills among some participants. The conversation emphasizes the importance of defining the modeling objectives to receive effective guidance.
