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

|                 | |       |        (per.pressure.V_flow[i+1]-per.pressure.V_flow[i])

|                 | |       |   d[1]=0     
|                 | |       | 
|                 | |       | 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.
