Hello, A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee. Applicant's name: Shashi Aithal Applicant's institution: ANL Applicant's division: MCS Project Name: CAT-engine-modeling Project title: Detailed Engine modeling using CONVERGE Associated funding: Other Systems: CATERPILLAR Cluster Science: The primary goal of this project is to study scaling issues using the commercial code CONVERGE with detailed chemistry. As a part of this exercise, complete 3-D simulation of a single cylinder diesel engine will be conducted. A series of chemistry models with increasing complexity (species and reactions) will be included. The objective is to find the optimum reaction mechanism and cores that will provide useful design information not obtained from 2-D and reduced chemistry models. Project description: The commercial CFD code, CONVERGE will be used to conduct 3-D diesel engine simulations. Currently, CONVERGE has been run on FUSION on 24 cores. Good scaling has been seen up to 24 cores. The current study aims to increase the computational load using greater resolution, bigger chemistry mechanism and possibly more complicated geometries. Scaling of CONVERGE on a larger number of cores will be studied. It is expected that 3 ANL researchers along with 3 CAT engineers will be using these core hours. Project URL: Requested allocation: 90000 Justification: The requester has used 0 hours of their initial startup project. In addition to approving an initial amount, please specify a Category and Subcategory for this project.
