This repository is for the creation of thermal hydraulics cooling system models for POWER9 type datacenters using the ExaDigit AutoCSM hierarchal templated approach.



- The current library provides basic models for creation of a datacenter. Future work should create different or modified models for different versions of subsystems and controls.



# Contents

- data - folder to house data for testing models

- json - input specifications for autogenerating the models

- POWER9Datacenter - Modelica library following AutoCSM templated approach

- fmus - folder containing pregenerated license-free fmus of the select example systems



# Dependencies

- Modelica IDE: Currently only tested with Dymola
@@ -31,5 +34,3 @@ At this stage you can use or explore. Suggested options include: 
- use the FMU created standalone or with ExaDigit,

- open up the project in Dymola using the autogenerated 'setup.mos' file and modify or explore the system model

- modify or create new input_specification files (see 'json' folder)
