Design of balance class - serves as storage and writer. Equations themselves call methods of Balance that add/modify mass, source and flux of various quantities and generate output.
One instance of Balance can handle several conservative quantities of the same type (e.g. mass of several substances or their phases).
The mass, flux and source are calculated as follows:
m(q,r) = ( M'(q) * solution + mv(q) )[r] f(q,r) = -( R' * ( F(q) * solution + fv(q) ) )[r] s(q,r) = ( S'(q) * solution + sv(q) )[r]
where M' stands for matrix transpose,
m(q,r)...mass of q-th substance in region r f(q,r)...incoming flux of q-th substance in region r s(q,r)...source of q-th substance in region r
and
M(q)...region_mass_matrix_ n_dofs x n_bulk_regions F(q)...be_flux_matrix_ n_boundary_edges x n_dofs S(q)...region_source_matrix_ n_dofs x n_bulk_regions SV(q)..region_source_rhs_ n_dofs x n_bulk_regions
mv(q)..region_mass_vec_ n_bulk_regions fv(q)..be_flux_vec_ n_boundary_edges sv(q)..region_source_vec_ n_bulk_regions R......region_be_matrix_ n_boundary_edges x n_boundary_regions
Remark: Matrix F and the vector fv are such that F*solution+fv produces outcoming fluxes per boundary edge. However we write to output incoming flux due to users' convention and consistently with input interface.
Note that it holds:
sv(q) = column sum of SV(q)
Except for that, we also provide information on positive/negative flux and source:
fp(q,r) = ( R' * EFP(q) )[r], EFP(q)[e] = max{ 0, ( F(q) * solution + fv(q) )[e] } fn(q,r) = ( R' * EFN(q) )[r], EFN(q)[e] = min{ 0, ( F(q) * solution + fv(q) )[e] } sp(q,r) = sum_{i in DOFS } max{ 0, ( S(q)[i,r] * solution[i] + SV(q)[i,r] ) } sn(q,r) = sum_{i in DOFS } min{ 0, ( S(q)[i,r] * solution[i] + SV(q)[i,r] ) }
where
fp(q,r)...positive (inward) flux of q-th quantity in region r fn(q,r)...negative (outward) flux of q-th quantity in region r sp(q,r)...positive source (spring) of q-th quantity in region r sn(q,r)...negative source (sink) of q-th quantity in region r
Remark: The matrix R is needed only for calculation of signed fluxes. The reason is that to determine sign, we decompose flux to sum of local contributions per each boundary element and check its sign. It is not possible to decompose flux using shape functions, since their normal derivatives may have any sign.
Output values (if not relevant, zero is supplied):
#time bulk_region quantity 0 0 0 mass source source_in source_out 0 0 0 #time boundary_region quantity flux flux_in flux_out 0 0 0 0 0 0 0 #time ALL quantity flux flux_in flux_out mass source source_in source_out integrated_flux integrated_source error
error = current_mass - (initial_mass + integrated_source - integrated_flux)
