This one-day course offers an introduction to setting up general flow cases in CONVERGE. CONVERGE is a multi-purpose CFD software that can be used for a wide variety of applications. Do you want to learn how to set up CONVERGE simulations for non-IC engine applications? If so, this general flow course is the one for you! Because CONVERGE has a fully automated meshing process, you do not need to spend any time preparing the volume mesh, which simplifies the surface preparation process.

During this course, you will have plenty of time for hands-on practice in CONVERGE Studio. You will start by working on simple geometries, and move to geometries that are more complex.

Upon the completion of this course, you will know how to:
  • Begin a new project in CONVERGE Studio
  • Import a surface geometry from a CAD program
  • Coarsen the surface triangulation to reduce the computational cost
  • Create boundaries
  • Manually repair surface defects
  • Prepare moving boundaries for motion
  • Set up solver parameters and data files
  • Set up appropriate boundary and initial conditions
  • Set up wall heat transfer modeling and output heat transfer quantities for thermal analysis
  • Set up additional modeling options (e.g., turbulence)

WHO SHOULD ATTEND THIS COURSE

This course is intended for new users to CONVERGE and CONVERGE Studio. This course can also be used as a refresher for experienced or occasional users of previous versions of CONVERGE and CONVERGE Studio.

CONVERGE Studio contains powerful tools for cleaning geometries with significant problems. In this workshop, we will discuss the advantages and limitations of several of these tools, focusing on the Coarsen, Boolean, Surface Healing, and Surface Wrapper tools. The Coarsen tool can be used to reduce the number of triangles in a geometry, which may be useful when working with a large geometry. The Boolean tool can perform Boolean operations including union, intersection, or difference. The Surface Healing tool, which was requested by many clients, can fix a variety of geometry problems at the click of a button. Finally, the Surface Wrapper tool can create watertight models by wrapping the existing geometry to create a new surface.

For several years CONVERGE has been able to interface with other software packages to model heat transfer in solids. Now CONVERGE can do both CFD and solid heat transfer modeling in the same simulation, which can simplify the process of predicting the temperatures in solids that are dependent on fluid interfaces, e.g., heads and valves in engines. This workshop will discuss conjugate heat transfer modeling in CONVERGE, including supercycling, which accounts for the disparate timescales in the solid and fluid domains by allowing the solid side of the simulation to progress with faster timescales than the fluid side of the simulation, and valve/seat contact resistance in engines, which is critical to accurate prediction of valve and head temperatures.
*This lecture includes hands-on CONVERGE Studio practice.

This workshop will focus on Urea/SCR engine aftertreatment modeling in CONVERGE. We will discuss urea decomposition and hydrolysis to ammonia, and we will describe how to set up urea-water spray modeling in CONVERGE. In addition, we will review wall film and wall interaction models, phenomena (filming, rebounding, stripping, and separating) that can lead to urea deposit formation, and the application of conjugate heat transfer modeling to obtain accurate wall thermal boundary conditions. We will discuss SCR surface chemistry approaches that use CONVERGE coupled with GT-SUITE. This workshop will include sample cases for practical Urea/SCR systems as well as validation cases. Finally, we will discuss future plans for improved engine aftertreatment modeling.
*This lecture includes hands-on CONVERGE Studio practice.

Rigid body fluid-structure interaction (FSI) modeling describes how the presence of one or more immersed objects affect the flow field and how the forces from the surrounding fluid influence the dynamics of the object. In this workshop we will discuss the theory behind FSI, the numerics of the dynamics solver, and the coupling of the dynamics solver to the flow solver in CONVERGE. We will consider several examples (a pressure relief valve, a spool valve, and an injector armature) that highlight the current capabilities of FSI modeling in CONVERGE. Finally, we will discuss complex examples that invoke a user-defined function coupled with FSI to model deforming bodies such as reed valve petals or a spring-close ball valve.

Every engine designer or manufacturer today wants to find ways to reduce engine emissions in pursuit of performance enhancement and conformation to emission standards. There are primarily two areas of focus for this pursuit: reduction of engine-out emissions and engine aftertreatment. In this lecture we will discuss the options available in CONVERGE and best practice recommendations to obtain accurate engine-out emissions. Detailed emissions modeling can be quite complex but can yield accurate predictions that match the measured data and trends across different cases. CONVERGE includes two detailed soot models: particulate mimic and particulate size mimic. CONVERGE contains acceleration strategies to make it feasible to account for detailed soot modeling (which includes gas-phase chemistry for its many sub-processes such as formation via precursor-species, coagulation, and oxidation) in engine simulations. In this course, we will also discuss NOx, unburnt HC, and CO formation in IC engines and gas turbines, look at the models available in CONVERGE, and discuss case setup recommendations to obtain accurate predictions.

CONVERGE features a sealing tool, which will dynamically eliminate gaps between parts that are moving relative to one another. The sealing process is dynamic in that the surface enclosing the computational domain is recreated at each time-step based on the boundary motion and the seal definitions, and thus this tool can be applied to a variety of cases, including two-stroke engines, Wankel engines, components connected by pins and bearings, pumps, and rotating machinery. We will give an overview of the sealing process and explain the geometric approach used to recreate the sealed surface from the boundaries and seal definitions. We will discuss best practices for surface preparation and case setup and demonstrate examples of applying seals to a check valve, a two-stroke engine, a Wankel engine, crankcase components, a gerotor pump, and a supercharger.

In this workshop we will discuss timely and popular topics in internal combustion (IC) engine modeling and some of the unique features of CONVERGE that yield efficient and accurate simulations. Ever wonder why predicted cylinder quantities do not match the measured data when you think you have set up the case correctly? We will talk about what you need to consider when the predicted cylinder pressures do not agree with measurements and how to assess the accuracy of your input parameters. With optimized cell counts via Adaptive Mesh Refinement and fast flow and detailed chemistry solvers, you can extend your simulation domain to include multiple cylinders to analyze cylinder-to-cylinder variation, run multiple cycles to understand cycle-to-cycle variation, and capture propagating pressure waves to resolve engine knock. We will draw case setup recommendations from published works that use CONVERGE.
*This lecture includes hands-on CONVERGE Studio practice.

Volume of fluid (VOF) methods are some of the most popular numerical techniques for locating moving and deforming interfaces between fluids in multiphase flow simulations. In this workshop we will discuss numerical details, example cases, and some validation calculations for the various VOF options in CONVERGE. One VOF method in CONVERGE is based on the species mass fraction equation and is appropriate for miscible or compressible multiphase flow calculations. One option in CONVERGE, which is based on the mass fraction VOF, is VOF-spray one-way coupling. In this option CONVERGE collects detailed fluid flow information near the nozzle exit during a VOF simulation and then uses this information to inject parcels for Lagrangian spray calculations. Another VOF method, which solves for the void fraction directly, is available in CONVERGE as two separate schemes: Piecewise-Linear Interface Calculation (PLIC) and High-Resolution Interface-Capturing (HRIC). These schemes have been tested on a range of problems including a breaking dam, a rising droplet, and spray injection, and each test case illustrates the ability of the method to track interfaces sharply.
*This lecture includes hands-on CONVERGE Studio practice.

In this workshop we will explore the vast array of user-defined functions (UDFs) that can be used to adjust existing models, implement new models, direct CONVERGE to calculate additional quantities, or initialize or reinitialize physical variables. We will discuss the different types of UDFs that CONVERGE supports as well as the process of compiling the UDFs and the necessary header files.
