Warning:
========
It is recommended that the volume flow rate versus pressure relation
of the fan or pump satisfies the minimum decrease condition

        (per.pressure.dp[i+1]-per.pressure.dp[i])
d[i] = ------------------------------------------------- < -0.000000
       (per.pressure.V_flow[i+1]-per.pressure.V_flow[i])

 is
  d[1]=0.000000

Otherwise, a solution to the equations may not exist if the fan or pump speed is reduced.
In this situation, the solver will fail due to non-convergence and
the simulation stops.
