Compare R-THYM model outputs to native EPANET run.
EPANET is an Extended Period Simulation (EPS) solver and cannot validate transient water hammer surges. Running validation will execute the model in steady-state (EPS) mode.

Global/base layout configurations and parameters. Serves as reference.
Parameters that differ from the base model. Counts on scenario cards match this list.

Each trial runs one EPS simulation for the menubar duration only. A longer economic horizon extrapolates that sample forward for scoring — it does not run additional hydraulics.
Configure decision variables below.
Default starting concentration for all junctions and pipes across the network (individual components can override this).
Water Quality controls will be hidden
You have custom water quality settings or component concentrations entered in this model.
Disabling Water Quality will reset custom initial concentrations, chemical dosages, and reaction coefficients back to default and hide water quality controls from all node panels.

R-THYM is a next-generation digital twin that unifies water infrastructure and energy management. Optimize your system's energy footprint, evaluate renewables, and pressure-test operations against high-fidelity hydraulic transients, entirely in the browser.
Designed and developed by Jason Lillywhite.
R-THYM utilizes the following third-party libraries and APIs to deliver robust simulation capabilities:
Please read our terms and conditions of usage before using the software.
1. ACCEPTANCE OF TERMS
By accessing or using R-THYM (the "Software"), provided by Lillywhite Water Solutions LLC, doing business as Lillywhite Water Technology Solutions ("LWTS", "we", or "us"), you agree to be bound by the terms of this End User License Agreement ("Agreement"), as well as our global Terms of Service. If you do not agree to these terms, do not use the Software.
2. PROFESSIONAL DISCLAIMER
The R-THYM platform is a tool for licensed professionals. Your use of this tool does not replace the professional judgment of a licensed engineer. You assume all responsibility for interpreting model results and integrating them into professional engineering work. Use of these tools does not constitute a Professional Engineering relationship, nor does it establish an expert-client privilege. A formal Professional Services Agreement (PSA) must be fully executed before any binding consulting or engineering design services commence.
3. LIMITATION OF LIABILITY & WARRANTIES
LWTS provides cloud-based digital twins and calculators "as is" and without warranties of any kind, whether express or implied. LWTS assumes no liability for the accuracy, completeness, or usefulness of the mathematical outputs. Numerical instability, inherent model approximations, and input errors may lead to inaccurate results. Any direct application of these tools to municipal infrastructure, industrial operations, or life-safety systems without independent, licensed verification is strictly prohibited and at your sole risk. In no event shall LWTS's aggregate liability exceed the total fees actually paid by you to LWTS in the twelve (12) months preceding the claim, or one hundred dollars ($100.00), whichever is greater.
