How to perform simulations on non-regular meshes?

Question

Hello! I'm new to cardiac electrophysiology simulation using open CARP. I have already performed simulations in cubic regions using the Block and BoxRegion classes, however, now I need to move my simulations to an atrial mesh and I don't know how to do that.

I would like to know a few things:

Are there any carputils classes for this purpose?

What do I need to read?

Is there any example that can help me?
 

Any help is welcome.

Thank you in advance.

carputils is great when you want to generate the meshes on the fly. For more complex meshes, you likely have them already as a file. The workflow then is to 

- if not already in the openCARP format, convert them (e.g. using meshtool: https://bitbucket.org/aneic/meshtool/src/master/)

- directly load the mesh with the raw openCARP command meshname (section 19.2 of the user manual: https://opencarp.org/documentation/user-manual)

I see that this is a frequent use case that's not covered yet by the examples on the openCARP web page. We'd be glad to see community contributions for such an example: https://opencarp.org/community/contribute

I created an issue for it: https://git.opencarp.org/openCARP/experiments/-/issues/41

Thank you! I also think an example using custom meshes would be very helpful as it would cover specific commands for cases like this that are not present in the currently available examples.
