CONVERGE Now Features Popular IFPEN Combustion Models

Posted by Gaelen Braithwait on

The 3-Zone Extended Coherent Flamelet Model (ECFM3Z) from IFP Energies Nouvelles (IFPEN) is the product of more than 20 years of research and validation. During that time it has established itself as one of the most widely used combustion models for internal combustion engines, with a reputation for accurate results and fast runtimes. Now, thanks to a collaboration between IFPEN and Convergent Science, the ECFM3Z is available to users of the CONVERGE computational fluid dynamics (CFD) software. The latest release of CONVERGE, version 2.3.14, has been carefully optimized to support the model. This release brings together the efficient, user-friendly features …


Argonne Engine Designs Ramp Up With HPC + CONVERGE

Posted by Gaelen Braithwait on

Powerful and efficient software from Convergent Science helps researchers to undertake combustion modeling on a massive scale A team from Argonne National Laboratory has set out to clean up the combustion engine, using one of the largest computational fluid dynamics (CFD) studies ever undertaken. Running the CONVERGE CFD code from Convergent Science, researchers at Argonne plan to carry out around 10,000 simulations concurrently as part of an investigation into gasoline compression ignition (GCI). “Improving engine efficiencies by even a few percentage points can take a big chunk out of our carbon footprint,” commented Sibendu Som, technical lead investigator at Argonne’s …

Ilmor’s impressive array of capabilities begins with design and spans precision manufacturing, component …


No Mesh, No Mess: Repairing Dirty Surfaces with Polygonica

Posted by Julian Toumey on

For CONVERGE CFD simulations, you do not have to generate a volume mesh. The robust and efficient automatic mesh generation algorithm in CONVERGE does the work for you, accelerating your CFD workflow. Even though you do not have to generate a volume mesh, you may need to perform surface repair operations to ensure your CAD surface meets certain requirements. To make the surface repair process even easier, CONVERGE Studio v2.3 (the graphical pre-processor for CONVERGE) includes the Polygonica geometry libraries. With an appropriate license, the Polygonica toolkit is integrated seamlessly into CONVERGE Studio v2.3. You have access to the Coarsen, …

Under Pressure: Relief from the Pain of Meshing for Pressure Relief Valve and Reciprocating Compressor Simulations

Posted by Clayton Grow on

As we explore new applications for CONVERGE, we look for products in which the flow and motion might be problematic for other CFD programs to capture. In the past year, we found an application that shared many characteristics with our flagship application, internal combustion engines: the reciprocating compressor. The two applications share a few key components: a cylinder, a piston reciprocating inside it, intake valves, and exhaust valves. In fact, a reciprocating compressor is sort of like an engine in reverse; instead of the volume of the cylinder expanding due to combustion driving the piston, the piston is controlled by …

A Call to Order

Posted by Kelly Senecal on

From the Toward Predictive Combustion blog series A long time ago in a galaxy far, far away… I wrote my last blog! Why has it taken me so long to blog again? Really there’s no excuse, but we at Convergent Science have been busy adding offices, forming partnerships, hosting user conferences, and expanding the CONVERGE user base. One thing that hasn’t changed is our dedication to bringing our users the most accurate CFD software for simulating flow and combustion in complex geometries. An often overlooked concept that is critical to achieving reliable CFD results is order of accuracy. This concept …


Convergent Science Joins the Clean High-Efficiency Diesel Engine VII (CHEDE-VII) Consortium

Posted by Daniel Goscha on

Building on more than 24 years of diesel engine research, the Clean High-Efficiency Diesel Engine VII (CHEDE-VII) Consortium was founded in November 2015 at the Southwest Research Institute. The Consortium is pursuing the world’s most efficient engines in order to meet industry needs in the next 5 to 10 years. The four-year multi-client consortium will consider worldwide markets and the effects of new technologies on these markets. Convergent Science is pleased to announce our membership in the CHEDE-VII Consortium. Dr. Daniel Lee, Vice President at Convergent Science, stated, “We are delighted to be members of CHEDE-VII.
