 If the calculation setting for the throughput ‘Coupling solids conveying’ is selected, the calculation in REX/PSI is performed as follows: If the calculation setting for the throughput ‘Coupling solids conveying’ is selected, the calculation in REX/PSI is performed as follows:
  
-Firstly, the melt-dominated throughput without solids conveying is calculated. From this, the pressure at the [[en:berechnungen:aufschmelzverlauf|melt vortex formation]] is calculated back from the screw tip and the known back pressure. The melt vortex formation is assumed to be the location up to which there is pure solids conveying and therefore serves as the interface between melt conveying and solids conveying.\\\+Firstly, the melt-dominated throughput without solids conveying is calculated. From this, the pressure at the [[en:berechnungen:aufschmelzverlauf|melt vortex formation]] is calculated back from the screw tip and the known back pressure. The melt vortex formation is assumed to be the location up to which there is pure solids conveying and therefore serves as the interface between melt conveying and solids conveying.\\
 Based on the known location and pressure at the melt vortex formation, the solids conveying throughput can then be calculated. This can be higher or lower than the melt-dominated calculated throughput. Based on the known location and pressure at the melt vortex formation, the solids conveying throughput can then be calculated. This can be higher or lower than the melt-dominated calculated throughput.
 If the calculated throughput is lower, the pressure at the melt vortex formation is recalculated with a reduced throughput from the tip of the leg. The back pressure of the solids conveying zone is therefore lower and the solids conveying throughput is therefore higher. \\ If the calculated throughput is lower, the pressure at the melt vortex formation is recalculated with a reduced throughput from the tip of the leg. The back pressure of the solids conveying zone is therefore lower and the solids conveying throughput is therefore higher. \\
