TRNSYS is described as 'Transient systems simulation program with a modular structure. It recognizes a system description language in which the user specifies the components that constitute the system and the manner in which they are connected' and is an app. There are four alternatives to TRNSYS for Windows and Mac. The best TRNSYS alternative is Aspen Plus. Other great apps like TRNSYS are Engineering Equation Solver, GateCycle Software and EBSILONProfessional.
Aspen Plus is a market-leading process modeling environment for conceptual design, optimization, and performance monitoring for the chemical, polymer, specialty chemical, metals and minerals, and coal power industries.
Aspen Plus is the most popular Windows alternative to TRNSYS.
Aspen Plus is the most popular commercial alternative to TRNSYS.
EES is a general equation solver that can solve thousands of coupled non-linear algebraic and differential equations. EES includes a library of thermodynamic and transport properties for hundreds of substances.
It is user friendly and easy to understand
Engineering Equation Solver is the most popular Mac alternative to TRNSYS.
GateCycle plant performance monitoring software predicts design and off-design performance of combined cycle plants, fossil boiler plants, nuclear power plants, cogeneration systems, combined heat-and-power plants, advanced gas turbine cycles and many other energy systems.
EBSILON®Professional is a system that simulates thermodynamic cycle processes and is used for engineering, designing, and optimizing plants.
