Simulator list
Blood Flow & Vascular Mechanics Simulator (Poiseuille Flow)
Physiology & Circulation
Real-time simulator for blood flow, wall shear stress & Womersley number. Calculate flow rates and evaluate atherosclerosis risk with stenosis.
Cardiac Output (Fick Principle) Simulator
Physiology & Circulation
Find the volume of blood the heart pumps per minute — the cardiac output — using the Fick principle, which treats oxygen as a natural tracer in the body.
Membrane Potential, Nernst Equation & Action Potential Simulator
Physiology & Circulation
Simulate action potentials & calculate membrane potentials. Use the Nernst & Goldman-Hodgkin-Katz equations with a real-time electrophysiology simulator.
Kidney eGFR & CKD Stage Simulator
Physiology & Circulation
Estimate the glomerular filtration rate (eGFR) from serum creatinine, age and sex using four equations side by side — CKD-EPI 2021 (race-free), CKD-EPI 2009, MDRD and Co…
Lung Compliance & Work of Breathing Simulator
Physiology & Circulation
Treat the lungs as an elastic bag and calculate the mechanical work of a single breath.
Neuron Action Potential Simulator
Physiology & Circulation
Simulate and animate neuron action potentials based on the Hodgkin-Huxley model. Visualize stimulus current and ion channel dynamics.
Pulmonary Function FEV1/FVC & COPD GOLD Simulator
Physiology & Circulation
From the forced expiratory volume in 1 second (FEV1) and the forced vital capacity (FVC), this tool computes the age-, height-, sex- and ethnicity-adjusted predicted val…
Ultrasound Doppler Blood Flow Simulator
Physiology & Circulation
Simulate Doppler ultrasound (PW and CW) for non-invasive blood-flow measurement in the carotid, cardiac and cerebral circulation.
Windkessel Model Simulator
Physiology & Circulation
Reproduce how the elasticity of the great arteries turns the heart's pulsatile beat into smooth blood flow, using a two-element Windkessel model.
Womersley Number Simulator — Characteristic Number of Pulsatile Blood Flow
Physiology & Circulation
Compute the Womersley number alpha = R sqrt(omega rho / mu) for pulsatile blood flow. Vary vessel radius, heart-rate, density and viscosity to map flow regimes.
