Detailed Description
template<unsigned ELEMENT_DIM, unsigned SPACE_DIM>
class MatrixBasedBidomainSolver< ELEMENT_DIM, SPACE_DIM >
A better Bidomain solver (better than BasicModomainSolver, from which it inherits), which computes the right-hand-side (RHS) vector of the linear system to be solved using matrix-vector products, rather than assembly. Massively more efficient than BasicBidomainSolver

Implementation of SetupLinearSystem() which uses the assembler to compute the LHS matrix, but sets up the RHS vector using the mass-matrix (constructed using a separate assembler) multiplied by a vector
- Parameters:
-
currentSolution Solution at current time computeMatrix Whether to compute the matrix of the linear system
