Dear Srinarayana, The way I learnt this was to take a simple example in the examples folder and hand draw the schematics for the node connections. I must disswade you from building a model from scratch. I've never done it, well almost never. Take an existing working model and adapt it. I would also recommend using tools which simplify the process, such as OpenStudio, or a commercial software. Your statement is confusing as you said that you had both a splitter and a mixer on the return path. This doesn't make sense. The mixer is on the return and the splitter is on the supply side right?
