Conduction Velocity Purkinje

Module: devtests.bidomain.cv_purkinje.run

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

This is an example that shall help tuning related parameters to obtain the desired velocity in the purkinje network.

Problem Setup

This example defines a minimalistic purkinje network attached on top of a thin cuboid on the domain (units in microns):

0.0  \leq x \leq 3 * dx3D

0.0 \leq y \leq 10000

0.0 \leq z \leq 1 * dx3D

And applies an electrical HIS stimulus on the upper side of the cuboid:

Conduction velocity is measured 500um after the cable begin and 500um before the cable end.

Usage

Following optional arguments with their default values are available:

./run.py --sourceModel = monodomain
         --propagation = R-D
         --dx3D        = 200.
         --resist      = 100.
         --cond        =   0.0006
         --effcond     =   1
         --dx1D        = 100.
         --tend        =  10.
         --suffix      = ''

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

./run.py --visualize

Tests

default

Generate a HIS activation sequence within a thin cuboid and compare V_m against reference.

  • Compare against stored reference: max_error(vm.igb)
