One of the most critical applications of computational fluid dynamics is in the field of civil engineering, water, and hydraulic structures. The applications in the field of hydraulic structures and civil engineering include the stepped spillway overflow simulation, cylindrical and lateral overflow dams, climate models and sedimentation. MR Company, with several years of experience in the field of computational fluid dynamics simulation, is ready to provide services in civil engineering-related fields. Our services include simulation with Fluent software. We also present simulation results in files (contours, plots, etc.) and full training to students and dear researchers.
