truncation error in adaptive time step BDF2

Post by inessvilarinho » 11 months ago

Hello,

I am modelling an absorption column at transient state and have to solve differential algebraic equations.

My idea is to use the BDF2 method with variable step size to solve the DAE system (that is very complex). However, I am not finding information about the calculation of the local error for DAEs.

Does anyone have experience in this area?

Thanks in advance for your help.

Regards,
Inês
