OPC Unified Architecture (UA) Client Plugin
The OPC UA Client Plugin for DWSIM enables mapping of monitored variables in an OPC Unified Architecture (UA) Server to Properties of DWSIM Flowsheet Objects (Unit Operations, Energy and Material Streams).
Pipe Network Unit Operation
Pipe networks are structures built to transport fluids between several supply and demand points. Transmission and distribution of natural gas are examples of services provided by pipeline networks.
In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
Neural Network Unit Operation
The Neural Network Unit Operation can use field/lab data to train and evaluate a Multi-Output Regression Artificial Neural Network to be used as a Unit Operation in your process model.
