THERMODYNAMICS & CYCLE ANALYSIS

Every state.
The whole cycle.

Build and refine cycle models in an engineering equation editor. Connect fluid properties, solved states, and process paths, then follow a design change through to performance.

01 / CONNECT THE STATES

Follow each state through the system.

Build the cycle with the agent, then inspect the solved states. Change a pressure, temperature, or efficiency and follow its effect through the table and property diagram.

Properties belong in the model.

Inspect enthalpy, entropy, density, and transport properties at each state. Autocomplete adapts the available property inputs to the selected fluid. The property-call builder lets you evaluate a call before inserting it into the model.

Process paths tell the story.

T–s, P–h, P–v, T–v, h–s, and psychrometric diagrams connect solved states. Recognized constant-property processes follow their paths through the diagram.

02 / COMPARE THE DESIGNS

Which input
moves the result?

Pin net power and efficiency, then drag a pressure input to see how both respond. Quick sweep plots the response across a range without setting up a table. A sensitivity chart helps you decide which inputs deserve a closer study.

Use Min/Max to search within bounds, and uncertainty propagation to see how input uncertainty reaches an output. Keep energy-balance checks visible with model assertions.

03 / SHARE THE REASONING

Make the result easy to review.

Carry the equations, substituted values, state tables, and plots into a calculation report. Or put inputs and outputs on a diagram and publish a calculation app.

FROM A SOLVE TO A HANDOFF

The calculation
travels with
the conclusion.

Formatted calculations show the symbolic relationship, the values and units substituted into it, and the result.

A published calculation app gives colleagues a way to change inputs and solve in a browser.
