Hyddown

Release with added vessel geometries such as DIN and ASME F&D in addition to flat-end vessel. A dynamic sizing method for fire relief valve has been added

Release including a 1-D transient heat conduction equation for calculating the temperature gradient through the vessel wall. Bi-material are also allowed, effectively enabling low conductivity materials and Type III/IV vessels to be investigated.

Hydrogen (or other pure gas phase species) pressure vessel filling and discharge calculations.

All basic functionality for single component gas pressurisation/depressurisation implemented. For steel vessels the results have been validated against experiments from the scientific literature. Rudimentary multicomponent capability.

This version is the first to be accompanied by a PyPi release.

First version working reasonably well with most needed features implemeting. Some work is required to provide meaningful messages to errors in input/yaml. Some convienece features are also lacking such as result arrays stored as pandas dataframe, optimisation/solvers for valve sizing is also lacking. More elaboration on heat transfer correlations is required as well as a transient 1-D heat transfer model to handle other materials than fairly dense metals.
