Fig. 4From: A cut finite element method for spatially resolved energy metabolism models in complex neuro-cell morphologies with minimal remeshingWe can see the fictitious domain \(\tilde{\Omega }\) for the heart shaped function, and the facets marked. In red the set of facets \(\mathcal {F}_G\) where we apply the stabilization term \(j([U]_{n+1},v)\) Back to article page
