`Phie Recovery`

Module: devtests.bidomain.phie_recovery.run

Section author: Anton Prassl <anton.prassl@medunigraz.at>

Test phie recovery in some nodes above a simple slab.

Problem Setup

This example defines a thin cuboid domain (units in microns):

$-1500 \leq x \leq 1500 -2500 \leq y \leq 2500 - 500 \leq z \leq 500$

Run a modomain simulation in a cuboid portion of tissue and recover the $phi_e$ signals above the corners of the geometry. Run the simulation with the same settings in postprocessing mode to recover $phi_e$ based on the previous simulation. Investigate the difference of the two simulation modes (i.e. experiment “0” [normal run] and experiment “4” [postprocess only]).

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

./run.py --visualize
