Detailed Description

template<unsigned ELEM_DIM, unsigned SPACE_DIM>
class BidomainCorrectionTermAssembler< ELEM_DIM, SPACE_DIM >

An assembler which computes the correction term to add to the RHS vector if using state variable interpolation (SVI), as well as determining which elements should be corrected on. The formula to determine which elements SVI is used is delta Iionic > TOL, where delta Iionic is the max difference between nodal ionic values, and TOL is chosen conservatively to be 1uA/cm^2^. See wiki page ChasteGuides/StateVariableInterpolation for more details.

This method is called by AssembleOnElement and tells the assembler the contribution to add to the element stiffness vector.

Parameters:
rPhiThe basis functions, rPhi(i) = phi_i, i=1..numBases
rGradPhiBasis gradients, rGradPhi(i,j) = d(phi_j)/d(X_i)
rXThe point in space
rUThe unknown as a vector, u(i) = u_i
rGradUThe gradient of the unknown as a matrix, rGradU(i,j) = d(u_i)/d(X_j)
pElementPointer to the element
