DAEQ1 : quasilinear DAE of index 1 DAEN1 : nonlinear implicit DAE of index one DAEQ2 : quasilinear DAE of index 2 NOHOL : quasilinear DAE of index 2 arising as models of mechanical multibody systems with nonholonomical contraints DAEQ3 : quasilinear DAE of index 3 EULAG : Euler-Lagrange equations of index 3

catal.f95 uses DAEQ1 for a catalytic converter problem eight.f95 uses DAEN1 for a "figure eight" problem ap_q2.f95 uses DAEQ2 for quasilinear DAE given by Ascher and Petzold in 1991 tskate.f95 uses NOHOL for a DAE modelling a scating body on a tilted plane ap_q3.f95 uses DAEQ3 for a modified version of a quasilinear DAE given by Ascher and Petzold in 1991 sevbd.f95 uses EULAG for the seven body Andrews squeezing mechanism
