CONVERGE Results Prominently Featured at WCX 2019

Madison, Wisconsin—March 27, 2019—CONVERGE results will be featured in more than 20 papers at the upcoming WCX World Congress Experience 2019. These papers span a wide variety of topics, including engine knock, aftertreatment, fuel injection, chemical kinetic mechanisms, GCI engines, conjugate heat transfer, and HCCI engine combustion. The diversity of topics speaks to CONVERGE’s innovative autonomous meshing capabilities, robust physical models, and ability to easily simulate complex moving geometries.

Convergent Science fosters collaboration with industry, academic, and government institutions, and this year’s WCX 2019 papers are a testament to those partnerships. The CONVERGE papers were authored by engineers at organizations such as the University of Oxford, IFP Energies nouvelles, Argonne National Laboratory, Tianjin University, Caterpillar Inc., Southwest Research Institute, Achates Powers, Universitat Politècnica de València, and Sandia National Laboratories.

The accompanying bibliography lists the full citation for each paper and the date, time, and location of the accompanying presentation.
