Simple carputils Example

This is a simple monodomain example that is primarily a demonstration of the carputils framework. This is not a real example but more of a template to base your own experiment on. It includes all typical building blocks of a cardiac electrophysiology experiment starting from mesh generation / loading, stimulus definition, conductivity and ionic model definition and launching the simulation. Finally, local activation times are determined as a postprocessing step and the results are visualized using meshalzyer. As such, this script can be a good starting point to build your own experiment using carputils.

This webpage only shows the basic documentation, to use it as a starting point for building your own experiment, you should look at the Python code of this experiment.

For detailed information on the different functions and parameters, consult the carputils documentation.

Problem Setup

This example defines a small cuboid on the domain:

\[-1.0 \leq x \leq 1.0\]\[-0.25 \leq y \leq 0.25\]\[-0.25 \leq z \leq 0.25\]

And applies an electrical stimulus on the \(x = -1.0\) face.

Usage

This example specifies just one optional argument, --tend. Use it to specify how long to simulate for after stimulus, in milliseconds:

./run.py --tend 100

As with other examples, add the --visualize option to automatically load the results in meshalyzer:

./run.py --tend 100 --visualize
