SimTwinTMRigorous simulation, continuously validated by live data, through EPSILON's proprietary interface
SimTwin
SimTwinTM links first-principles process models directly to plant data — delivering a living digital twin that predicts behaviour instead of just recording it.
Define systems of equations that predict outputs from sensor inputs. Simulation results are reconciled against real-time data continuously, so the model fit is always known, and what-if studies run against today's plant, not last year's design case.

Steady-state & dynamics
Switch seamlessly between steady-state, rating and dynamic modes in one model.
Live model validation
Reconcile simulation results against real-time data to keep the twin continuously accurate.
Equation-oriented solver
Robust numerics handle complex recycles and constraints efficiently.
What-if case studies
Test operating changes safely inside the model before touching the real plant.
Practical use case
From imported model to live-bound digital twin
Import the model
Bring in an existing flowsheet as a DWSIM file, upload an Excel workbook, or paste formulas. SimTwinTM extracts the topology — streams, unit operations, compounds — and validates it before it can be saved.
Declare inputs & outputs
Every property the model exposes — temperature, pressure, mass and molar flow, enthalpy — is switched to Input, Output or Constant. Inputs feed live plant data into the solve; outputs read computed results back out.
Bind live tags
Each input is bound to a historian tag with a searchable picker. From then on the simulation runs against telemetry, and every output becomes a trackable data source that NexusTM formulas, trends and dashboards can reference directly.
