Finite volume method simulation of solids transport, melting, and metering in single screw extruders. Supports conventional single-flighted screws, barrier screws of Maillefer / Uniroyal and parallel flight (MC3 / Barr and Dray and Lawrence) designs, and screws with mixing (blister ring, Maddock or Egan) elements. Results include solid bed profile, pressure build-up and bulk temperature along the screw axis, along with extruder output, power requirement, torque and average residence time. NEXTRUCAD replaces our original extrusion simulation package EXTRUCAD.
CALCUTRUDE LITE version is currently available (pressure drops, shear rates, shear stresses and temperature rise in dies).
Full version in progress (extruder output, torque, energy, calendering, extrudate swell, extensional viscosity and much more).
Determination of polydispersity measures from rheological data.
Based on the Finite Difference Method, chillWARE Cooling Simulation allows a detailed calculation of cooling processes for extruded plastic products. chillWARE assists you to increase energy efficiency of cooling processes or solve problems regarding product quality, e.g. determination of residual stresses and degree of crystallization. It is also possible to calculate optimized output rates for a given cooling section configuration.

Ever since we started using the OpenFOAM (www.openfoam.org) for fully 3D simulations we have "retired" several of our 2D software packages which have served POLYDYNAMICS INC and its numerous customers around the world.
Software products developed and licensed in the past:
PROFILECAD: Finite element method simulation of flow through arbitrarily shaped extrusion dies. Profile die design is done by determining a sequence of cross-sections using the principle of cross-flow minimization.
FLATCAD: Control volume method simulation (using the Hele-Shaw flow approximation) of downstream and laterally spreading flow in coathanger dies for flat film and sheet. Output non-uniformities, pressures, temperatures, shear stresses, shear rates, and residence times are all predicted.
SPIRALCAD: The control volume method is used for flow simulation along the spirals and between the mandrel and the body of spiral dies for blown film and tube production. Output non-uniformity prediction, pressure, and other flow variables are predicted.
LAYERCAD: Detailed examination of combined melt flow streams (up to 20) for multilayer blown film and multi-manifold sheet coextrusion, based on the finite element method with the assumption of locally fully-developed flow.
B-FILMCAD 2: Simulation of the bubble formation process in film blowing. Results include thickness variation, film temperature variation, MD (machine direction) and TD (tangential direction) strain rates and stresses.
POLYCAD 2-D: General purpose finite element method non-isothermal melt flow simulation package for 2-D and axisymmetric problems. Includes Power-law, Carreau, Log-polynomial, and Newtonian models for viscosity and correlations for first normal stress difference and extensional viscosity. Useful for analysis of die flows, extrudate swell, calendering, coextrusion, wire coating, and injection molding.
XTRU-XPERT: Simple extrusion calculations and troubleshooting of single screw extrusion problems and product defects (i.e. surging, screw and barrel wear, gels, sharkskin and melt fracture, poor mixing).
VISCOFIT: A regression package for fitting viscosity data at different temperatures to Power-Law, Carreau, Log-polynomial, and Newtonian models. The Rabinowitsch correction is used to convert apparent data.
POLYBANK: A data bank with material information for use with other Polycad Software Suite packages.
CALENDERCAD: Simulation of melt flow in the calender gap, with prediction of torques and pressure variation.
T-FORMCAD: Finite element method simulation of sheet thinning in thermoforming without plug assistance. Full 3-D capabilities (no longer available for licensing).
