Carollo upgrades to Coreform Cubit for CFD meshing of water treatment facilities
Carollo selects Coreform Cubit for computational fluid dynamics (CFD) meshing to replace the venerable GAMBIT software.
Carollo Engineers is the largest firm in the United States whose focus and practice, since 1933, have been dedicated solely to water-related engineering. The Carollo Research Group is a diverse team of engineers, scientists, and researchers located in offices across the country who work collaboratively to connect fundamental and applied research to practical, innovative, and reliable water solutions for their clients.
Carollo is an industry-leading pioneer in the use of computational fluid dynamics (CFD) as a critical hydraulic and process design tool, with over 30 years of experience applying this technology to their daily work. Their portfolio of applications ranges from projects that improve pump station hydraulics, optimize disinfection processes, and model sedimentation to operational simulations of complete treatment plants.
To run accurate CFD simulations, Carollo first creates high-quality mesh representations of their geometry, which they then send to various CFD solvers, including ANSYS Fluent. When Carollo first began their CFD work decades ago, they chose the venerable GAMBIT meshing software to create these representations. In 2015, Carollo reevaluated their CFD meshing needs and decided to upgrade their software to Coreform Cubit.
Carollo’s optimal CFD meshing choice is Coreform Cubit for the following reasons:
Up-leveling with familiarity: Though it boasts additional advanced meshing capabilities, Coreform Cubit has a similar workflow to GAMBIT; in fact, the GAMBIT code was forked from Cubit. As such, Carollo achieved an upgrade in their meshing capabilities while securing a gentle learning curve for their various users.
Streamlined usability: Coreform Cubit offers Carollo a comprehensive toolset for streamlining CAD preparation and mesh generation. Incorporating the 3D ACIS Modeler (ACIS) geometric modeling kernel, Coreform Cubit’s powerful simulation modeling capabilities allow users to build their simulation geometry of wastewater systems from scratch and then also create the mesh in the same software. Carollo also reports that the boundary layer technology in Coreform Cubit is superior to that of GAMBIT for their needs.
Diverse solutions: Coreform Cubit is an independent mesher and preprocessor that interfaces with over forty solvers, giving Carollo flexibility to explore different CFD solver solutions in the future.
Fair pricing: Coreform Cubit’s pricing is attractive and extremely competitive against other products available on the market.
Since Carollo’s transition in 2015, Coreform Cubit has served as a part of their daily workflow, increasing user confidence and saving valuable time and costs. See the figures below for an example of how Carollo uses Coreform Cubit to prepare accurate meshes to optimize flow and overall system efficiency in a wastewater treatment plant.
The Carollo Research Group actively publishes results as they continue to establish best practices in CFD for water treatment facilities. They have used Coreform Cubit to generate the meshes in several publications, including those listed below.
