HAMPPSTerS v6.1 minor update

In this update, the LHS sampling script was been completely revamped to handle the LHS as a single abstract parent class from which each case study is derived as a child class. Each child class is responsible for the individual parameter calculations needed to complement the sample space as well as the physical restrictions belonging to each case. The parent class handles the LHS building and parameter add universally. Functionality remains the same in the run.py scripts but each child class is now imported instead of a given run function.

HAMPPSTerS Ver6.0 release

Code framework has been refactored, isolating the general CFD and HPC scheduling tasks in an abstract Parent class. Locally, CFD scheduling now only contains base methods used by all other parametric studies, whilst mixing studies have been separated into an individual script. HPC script call has been amended to read an additional argument to distinguish between specific case studies and accordingly enter the study child class.
