Getting Started with Electrophysiology (MFHN model)


  • This example will guide you through the creation of a new electrophysiology model using a Modified Fitzhugh-Nagumo model (Rogers & McCulloch, 1994, IEEE Transactions on Biomedical Engineering, 41:743-757) to explore a reentrant wave case.

  • The files required are located in the examples directory on your Continuity client .../continuity/pcty/examples/electrophysiology20/

  • The steps below are saved in a script that can be found in [here] and can be executed automatically with File→Read→Python script

Start Continuity

Create Mesh

Formulate Electrophysiology Problem

Compute and Render Solutions

  • Electrophysiolgoy→Solve→Integration...

    • Choose a 'File name' distinction
    • Input 900 ms as the duration for the simulation

    • Go to the Output tab and input a display solution interval of 20 steps

    • Go back to the Integrate tab and click on OK

  • When your simulation has finished, you can render the solutions by Electrophysiology→Render→Render Solution...

    • Set Min Value to 0

    • Set Max value: to 1

    • Click OK to view an animated color map of the Action Potential propagation
