Abstract Modeling of complex systems requires large and expensive computational systems. Costs and processing time can be reduced by more than half in a well‐managed cloud environment. Modeling the flow of ethylene propylene diene monomer (EPDM) through a Garvey die was achieved by employing the latest cloud computer technology commercially available at a modest cost. The description of the stress–strain behavior for EPDM was done using the Otswald‐de Waele model. The results demonstrate that at higher velocities, the flow lines do not follow a smooth profile upon exiting the die, which indicates instabilities that may affect on the finished surface. Prediction of extrudate flow instabilities gives a computational option to make an initial estimate of permissible extrusion speeds.
