Summary of how the cardiac code works in terms of ODEs, PDEs and MPI

[mirams]

Question from David Benn:

I worked with Chaste several years for cardic electro-physiology ago and I want to recall some aspects of it that I have forgotten (quite a bit)
I’d like to start with a summary of the role of ODEs, PDEs and MPI and their intersection with the cell models (as declared in CellML) for Chaste. Is there a summary doc that you could point me to?

Thanks.

[mirams]

We have an in-depth discussion of how the finite element scheme for the PDEs is derived and implemented within Chaste in this PDF:
https://chaste.github.io/docs/fem_implementation.pdf

In terms of the CellML/action potential models, there is one placed at each node of the finite element mesh, they just need to present the correct units (conversions from CellML done automatically - the best introduction is probably https://doi.org/10.3389/fphys.2014.00511 on the capabilities on that side, as well as some newer features (singularity removal) in chaste_codegen which recently replaced the old Python2 PyCML)

Thanks @mirams
When I looked at this in discussion with @fcooper8472 yesterday I found Pras' old lecture notes. They are really accessible but may be out-dated.

Thank you @mirams and @jmpf! Much appreciated. I will let you know if I have further questions after reading those docs.
