Hello

where can I find what the boundary conditions are that are used in both monodomain and bidomain simulations? Can these ones be changed?

Thanks a lot in advance!

Cheers

Lore

By default, homogeneous Neumann boundary conditions (no flux) are assumed. This could indeed be described more clearly in the manual. Contributions are appreciated:

https://git.opencarp.org/openCARP/openCARP/-/issues/140

These examples provide further information on more complex boundary condition scenarios:

Thank you for the quick reply!

Are these boundary conditions the ones from myocardium to bath or for the end of the bath or both?

For bidomain with bath, the "end of the bath" has homogeneous Neumann boundary conditions for Phi_e.
At the tissue to bath boundary, Phi_i has homogeneous Neumann boundary conditions as well whereas for Phi_e continuity from tissue to bath is enforced.
