Arena-flow, by CPFD, simulates the blowing/shooting and curing of sand cores and molds. Arena-flow is trusted by OEMs, foundries, equipment manufacturers, and core/pattern shops to complement metal flow and solidification software, resulting in optimized processes and cores that are right the first time!
Using Arena-flow our clients:
Arena-flow was designed from the ground up to capture discrete sand filling physics to accurately simulate core blowing/shooting and curing behavior which is difficult (or impossible) to predict using adaptations to metal flow and solidification software. It is best suited for high-complexity, high-volume cores made via the following processes:
Process Modeling: Sand Core Blowing*, a publication presenting Arena-flow’s early capabilities, won the 2003 AFS Howard F Taylor Award from the American Foundry Society in recognition of the paper having the greatest long-range technical significance in the field of cast metals technology. Over two decades later the impact of Arena-flow is still going strong!

CPFD announces the release of Arena-flow® 12.0 that allows users to initialize a case using sand information from a previous simulation and other usability enhancements.
Fondrémy Inc., in collaboration with LAEMPE REICH, used Arena-flow to improve casting quality and reduce tooling costs for a complex water pump housing.
CPFD Software is proud to announce that it has entered into a software licensing agreement with LaempeReich for CPFD’s Arena-flow simulation software.
CPFD Software is pleased to announce the renewal of its software licensing agreement with Aurrenak & Loramendi Group, reaffirming their continued use of the Arena-Flow simulation software.
This webinar introduces Arena-flow, our foundry simulation tool for sand core and mold blowing/shooting and curing.
Arena-flow is used to simulate the filling of an automotive cylinder head water jacket core through an integrated core print.
Arena-flow, by CPFD, models the air-driven sand flow critical to the creation of consistent, high-quality sand cores and molds for many processes including cold-box, shell, inorganics, greensand, hot-box, and warm-box. This video illustrates how air flow drags sand into the cavity.
This video shows how a mixture of gas and air progresses inside a core box, as the sand has contact with gas, air, cured sand, in this instance cured sand is shown as transparent dark grey.
This video demonstrates Arena-flow’s inorganic curing capabilities for dehydrative systems.
