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