 might be structurally or numerically singular for variable tabsSouth1[2].m_flow since U(2,2) = 0.0. It might be hard to solve. Compilation continues anyway.
Error: Internal error IndexReduction.pantelidesIndexReduction failed! System is structurally singular and cannot be handled because the number of unassigned equations is larger than the number of states. Use -d=bltdump to get more information.
