We just published the first release of DHNx!
With DHNx, we introduce a package for district heating network optimization and simulation models.
The aim of DHNx is to develop a library for the planning and modelling of district heating network systems. The package has two main features: the optimization (routing and sizing) of district heating network systems, and the hydraulic and thermal simulation of a district heating network with given pipe diameters.
Examples can be found here here.
