Computes the right hand side of (1). The RHS is everything except the term that contains the time derivative . In case of a Discontinuous Galerkin projection, the routine WeakDGAdvection will be called which then calls v_GetFluxVector and v_NumericalFlux implemented in the PulseWavePropagation class.

Calculates the second term of the weak form (1): The variables of the system are ${U} = [A,u]^T$ physfield[0] = A physfield[1] = u flux[0] = F[0] = A*u flux[1] = F[1] = u^2/2 + p/rho p-A-relationship: p = p_ext + beta*(sqrt(A)-sqrt(A_0))

Initialisation routine for multidomain solver. Sets up the expansions for every arterial segment (m_vessels) and for one complete field m_outfield which is needed to write the postprocessing output. Also determines which upwind strategy is used (currently only upwinding scheme available) and reads blodd flow specific parameters from the inputfile
Gets the Material Properties of each arterial segment specified in the inputfile from section MaterialProperties
Also gets the Area at static equilibrium A_0 specified in the inputfile.
Having found these points also extract the values at the trace points and the normal direction consistent with the left adjacent definition of Fwd and Bwd
