-In REX Next Generation, you have the option of defining specific mould elements in order to calculate key process variables such as the pressure at the screw tip. This function is particularly relevant for the precise simulation and optimisation of plastics processing, as the geometry of the mould elements has a direct influence on the material flow and pressure distribution.+In REX Next Generation, you have the option to define specific die elements in order to calculate key process parameters such as the pressure at the screw tip. This function is particularly relevant for the precise simulation and optimization of polymer processing operations, as the geometry of the die elements has a direct influence on the back pressure and, consequently, on the throughput.

These tool elements cover the most common cross-section shapes used in practice. The following elements are available:
  
-      * **Conical circular cross-section:** This element describes a circular cross-section whose diameter varies over its length. This geometry is often used for transitions or nozzles that guide the material into a narrower area.+      * **Conically shaped tube element:** This element describes a circular cross-section whose diameter varies over its length.

This geometry is often used for tools that need to ensure an even distribution of material over a larger area.+      * **Conically shaped rectangular element:** A rectangular cross-section whose width and/or height varies along the length of the die.

-Another important feature is the ability to specify the number of elements connected in parallel. This makes it possible to use several identical mould elements in parallel in a process in order to simulate the material flow through several channels simultaneously. This function is particularly useful for processes with multi-channel or multi-strand extrusion.+Another important feature is the ability to specify the number of elements connected in parallel.

-The precise definition and arrangement of the mould elements is crucial for the quality of the simulation results. By taking into account the various geometries and their influence on the material flow, you can perform precise calculations, such as the pressure at the screw tip or the speed of the material outlet. These parameters are of great importance in plastics technology, as they have a direct influence on the quality of the end product.+The precise definition and arrangement of the mould elements is crucial for the quality of the simulation results.
