 For degassing screws only, three options can be selected: For degassing screws only, three options can be selected:
-  * **to degassing zone**: Standard, the melting calculation stops at the first degassing zone +  * **till degassing section**: Standard, the melting calculation stops at the first degassing section 
-  * **from degassing zone conventional**: conventional melting also in/after the degassing zone. However, if disperse melting has already been forced, for example by a shearing part before the degassing zone, disperse melting will continue to be calculated. +  * **conventional melting after degassing section**: conventional melting also in/after the degassing section. However, if disperse melting has already been forced, for example by a shearing part before the degassing section, disperse melting will continue to be calculated.

-  * If //Iterate temperature// is **not** selected, the calculation is only calculated with an //initial temperature profile//. This is described by a linear progression of the temperature from the melting temperature ($T_G$ / $T_K$) at the front edge of the hopper to the specified final melt temperature (see [[en:eingabe_der_verfahrensparameter:eingabe_der_verfahrensparameter|necessary process parameters]]) at the screw tip. For degassing extruders, the specified final melt temperature already applies to the start of the first degassing zone and remains constant thereafter. \\ If //Iteration of the final temperature// is selected, the calculated temperature profile is used iteratively for a new calculation of the entire process until a stationary state (no change in the final temperature) is reached.+  * If //Iterate temperature// is **not** selected, the calculation is only calculated with an //initial temperature profile//.
