Public Members

realtype time

Time of discontinuity.

AmiVector x_post

Post-event state vector (dimension nx).

AmiVector x_pre

Pre-event state vector (dimension nx).

AmiVector xdot_post

Post-event differential state vectors (dimension nx).

AmiVector xdot_pre

Pre-event differential state vectors (dimension nx).

std::vector<int> root_info

Array of flags indicating which root has been found.

Array of length nr (ne) with the indices of the user functions gi found to have a root. For i = 0, …, nr: 1 or -1 if gi has a root, and = 0 if not. See CVodeGetRootInfo for details.

std::vector<realtype> h_pre

Flag indicating whether a certain Heaviside function should be active or not, pre-event value (dimension: ne)

AmiVector dx_post

time derivative of state (DAE only) post-event

std::vector<realtype> total_cl_pre

Total abundances for conservation laws (dimension: nx_rdata - nx_solver)
