Add IDA solver for initial conditions root-finding

Open Dharshannan opened this issue 3 months ago • 1 comments

Description

Currently the IDA solver uses the Casadi solver for initial conditions root finding. The Casadi solver fails for any index 2 DAE systems. However, despite IDA capable of solving index 2 DAE systems, if initial root finding is disabled the solution fails (likely due to poorly defined initial conditions).
