Transient tool

From the ISAAC Dynamics creators Transient is born, an advanced dynamic simulation tool.

  • 100% ID model compatibility
  • Enhanced Thermodynamic tables
  • Enhanced tool external connectivity
  • New features

TransientGroup at SolarPACES 2017 in Santiago (Chile)

TransientGroup will be present at SolarPACES 2017 in Santiago, Chile from September 26 to 29.

Two articles will be presented by Matteo Losito, Sr. Process Engineer,  whose titles are:

  • Dynamic Analysis of Extraordinary Operations of MS Central Receiver (in collaboration with DLR, Germany)
  • 24h Dynamic Simulation of a CSP Solar Tower Demo Plant



ID Connect

The new version of ISAAC Dynamics, ID 3.0, introduces the new tool ID Connect.

ID Connect allows users to connect ISAAC Dynamics with other software via TCP/IP communication protocol boosting ISAAC Dynamics capabilities beyond the platform limits. It will be also possible to split the calculation over many machines and speed up the process.


TransientGroup in Rome at University of La Sapienza – for NESTER

TransientGroup presented the company and its activities in Rome – University of La Sapienza – during a 3 day workshop entitled “ENEA’s perspective on the development of Concentrating Solar Thermal Technologies”, together with other companies of CST context in Italy like ENEL, ENI, Archimede Solar Energy, ESE and others.

Real Gas Tables

TransientGroup has developed a new library in order to evaluate thermodynamic and transport properties of more than 100 real pure fluids, real gas mixtures and the most common refrigerant fluids. The new library is supplied with the following thermodynamic models: Peng-Robinson, NIST, GERG-04. It is possible to create graphs as well and interrogate the tables through a user-friendly interface.


ISAAC Dynamics at Solar PACES 2015

Our dynamic platform has been presented at Solar Paces Conference in Cape Town (South Africa, 2015)  in collaboration with Alstom Power Inc. – Windsor (Connecticut). The paper entitled “Transient simulation of molten salt central receiver” can be downloaded from the American Institute of Physics website clicking on the link
