The die module is divided into two considerations of dies:

• die-tool
• large-area melt filter

Both tools are used to calculate the decrease in pressure and both can indicate the pressure at the screw tip during a SIGMA-simulation. The die-tool and the large-area melt filter can be intercoupled as well as used separately during a simulation.

The basis of calculation in the case of the die-tool is based on analytical methods and in the case of the large-area melt filter on the network theory.
