 All settings for the calculation are defined in the dialog Calculation Settings.
-  * **Pressure profile:** Within this calculation it can be chosen between the polynomial (s. [[en:grundlagenhandbuch:schmelzefoerderung:linearer_druckansatz_und_polynomansatz]]), the linear (s. [[en:grundlagenhandbuch:schmelzefoerderung:linearer_druckansatz_und_polynomansatz]]) and a regression calculation model (s. [[en:grundlagenhandbuch:schmelzefoerderung:regressionsansatz]]). The linear one bases on an analytical approach based on the theory of single screw extruders. Against this the polynomial calculation and the regression model base on an approximation of numerical results. By selecting the modified option the treatment of the nip region in the calculation can be chosen. From our experience the regression model that was newly implemented in SIGMA 4.5 gives the most reliable results.

   * **Melting profile:** Within this calculation it can be chosen between five different models: Compacted, Disperse, Binary, Modified Disperse and 2D Disperse. The compacted calculation model is a modified Tadmor model as it is known in the theory of single screws (s. [[en:grundlagenhandbuch:aufschmelzberechnung#aufschmelzmodell_fuer_kompaktierte_feststoffe | Compacted Model]]). The disperse model presumes that the granulate melts isolated (s. [[en:grundlagenhandbuch:aufschmelzberechnung#aufschmelzmodell_fuer_dispers_verteilte_fuellstoffe|Disperse Model]]). The binary model takes the melting of binary systems (blends and compounds) into account. The modified dispersed melting model is based on the dispersed model. However, the finite influence duct dimension, the influence of the convection as well as the influence of the particles on the stream will be included additionally within this model (s. [[en:grundlagenhandbuch:aufschmelzberechnung#modifiziertes_disperses_aufschmelzen|Modified Disperse Model]]). The 2D disperse melting model is a further expansion of the modified disperse melting model and is recommended for the calculation of the melting of particles bigger than 2 mm (s. [[en:grundlagenhandbuch:aufschmelzberechnung#d_disperses_aufschmelzen|2D Disperse Model]]).
-  * **Temperature profile:** Within this calculation it can be chosen between a traditional rectangular model (s. [[en:grundlagenhandbuch:massetemperatur#urspruenglicher_ansatz | traditional rectangular model]]), a new twin screw model (s. [[en:grundlagenhandbuch:massetemperatur#modifizierter_ansatz | modified twin screw model]]) and a 2D temperature model (s. [[en:grundlagenhandbuch:massetemperatur#d_modell | 2D temperature model]]). If a heat flow (s. [[en:grundlagenhandbuch:zylinderwaermestroeme | heat flow]]) is considered for the temperature calculation, SIGMA adapts the barrel temperature.
-  * **Power profile:** Within this calculation it can be chosen between a traditional rectangular model (s. [[en:grundlagenhandbuch:drehmoment_und_antriebsleistung#urspruenglicher_ansatz | rectangular model]]), a new twin screw model (s. [[en:grundlagenhandbuch:drehmoment_und_antriebsleistung#modifizierter_ansatz | modified twin screw model]]), an enthalpy based model (s. [[en:grundlagenhandbuch:drehmoment_und_antriebsleistung#enthalphiemodell | enthalpy based model]]) and an enthalpy based model with heat flow.
-  * **Degree of dispersion:** For the calculation of the degree of dispersion it can be chosen between a model for the degree of dispersion and an energy model.
+  * **Temperature profile:** Within this calculation it can be chosen between a traditional rectangular model (s. [[en:grundlagenhandbuch:massetemperatur#urspruenglicher_ansatz | Traditional Rectangular Model]]), a new twin screw model (s. [[en:grundlagenhandbuch:massetemperatur#modifizierter_ansatz | Modified Twin Screw Model]]) and a 2D temperature model (s. [[en:grundlagenhandbuch:massetemperatur#d_modell | 2D Temperature Model]]).
