Class CalibrationFrameworkExample

java.lang.Object

neqsim.process.calibration.CalibrationFrameworkExample

public class CalibrationFrameworkExample
extends Object

Example demonstrating the new calibration framework for online parameter estimation.

This example shows how to:

1. Set up a process system with tunable parameters
2. Configure the EnKF estimator
3. Run pre-deployment validation tests
4. Perform live parameter estimation

The scenario involves a 4-well production system with pipes flowing to HP/LP manifolds. We estimate the heat transfer coefficients of each pipe based on manifold temperature measurements.
