Bodylight.mo

Bodylight library is a fork of Physiolibrary, version 2.4.1 ( http://www.physiolibrary.org ) and is a free open-source Modelica library designed for compartmental modeling of human physiology. This library contains basic physical laws governing human physiology, usable for cardiovascular circulation, metabolic processes, nutrient distribution, thermoregulation, gases transport, electrolyte regulation, water distribution, hormonal regulation and pharmacological regulation.

Library description

The origin of the Modelica Physiolibrary, a Bodylight predecessor, was in the initial version of our Physiomodel ( http://www.physiomodel.org ) implementation, which is based on model of human physiology called HumMod. As the successors of Guyton's Medical Physiology School write, the original HumMod model is “The best, most complete, mathematical model of human physiology ever created” ( http://hummod.org ).

We are also developing many types of smaller physiological models for use in medical education, so it was essential to separate this library from our HumMod Modelica implementation. This separation improves the quality of the next HumMod release and provides a useful Modelica library to modelers in this bioscience. The library contains only carefully-chosen elementary physiological laws, which are the basis of more complex physiological processes. For example from only two type of blocks (Chemical.ChemicalReaction and Chemical.Substance) it is possible to compose the allosteric transitions or the Michaelis-Menten equation.

Library contains also the icons for higher level (HumMod) subsystem implementations:

Installation

  • Bodylight/package.mo can be directly opened by each Modelica environments.

  • Dymola support of physical units:

    • Using Windows batch script: call "Bodylight\Resources\Install\Dymola\install.bat"
    • Manually: copy the Bodylight/Resources/DisplayUnits/displayUnits.mos over dymola-install-dir/insert/displayUnits.mos

Prerequisities

Current release

Download Bodylight.mo

Upgrading from Physiolibrary 2.4.x to Bodylight 1.0

In Dymola, run a conversion script "Bodylight/Resources/Conversions/ConvertFromPhysiolibrary_2.4.1.mos" prior to loading your project. Project will be convertet to Bodylight on load.

Alternatively, use [Bodylight\Resources\Conversions](https://github.com/creative-connections/Bodylight/Resources/Conversions/UpdatePhysiolibrary2.4ToBodylight1.0.bat) to simply rename Physiolibrary 2.4.x to Bodylight 1.0. Just place this into root of your project and run.
