Detailed Description

template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class BidomainNeumannSurfaceTermAssembler< ELEMENT_DIM, SPACE_DIM >

Assembler which sets up the surface integral integrals for the bidomain equations, assuming that the boundary conditions are written: div(sigma_i grad phi_i) . n = g1 and div(sigma_e grad phi_e) dot n = g2.

These are not 'natural' boundary conditions for the para-elliptic bidomain equations (natural BCs for the second

Hence we don't use the NaturalNeumannSurfaceTermAssembler and have a special class here. It means that any BCs specified for bidomain and put in a BoundaryConditionsContainer should be for div(sigma_i grad phi_i) . n and div(sigma_e grad phi_e) . n.

protectedvirtual

This method returns the vector to be added to full vector for a given Gauss point in BoundaryElement, ie, essentially the INTEGRAND in the boundary integral part of the definition of the vector. The arguments are the bases, x and current solution computed at the Gauss point.

Parameters

rSurfaceElement	the element which is being considered.
rPhi	The basis functions, rPhi(i) = phi_i, i=1..numBases
rX	The point in space

Returns

stencil vector
