During the compilation, a WARNING is displayed to notify the solver switch.
xcos_simulate():
WARNING: Diagram has been compiled for implicit solver
switching to implicit Solver
scicos_simualte(): no warning, so no switching.
If the diagram contains continuous states, xcos and scicos are supposed
to detect the problem type (ODE or DAE) and switch to the default one
(Sundials/BDF-Newton for ODE and Sundials/IDA for DAE) if the Setup
solver is not adapted.

Hi Paul,
Thank you very much for your answer. I have changed the model after your
first answer but I forgot to attach it again. I did use the END block.
Thanks for highlighting the difference of solver type. It seems that
Sundials/IDA gives the result I expect. Can you tell me where to check the
solver that have been used for the simulation? (The only variable generated
by running the simulation is %scicos_prob but I can not open it).
