In this tutorial, we will be using CFD Suite, a powerful computational fluid dynamics software, to simulate a 2D external flow. This tutorial will focus on demonstrating a speed demo of the simulation process, providing step-by-step instructions on how to set up the simulation, run it, and analyze the results.
Step 1: Set up the Geometry
The first step in any CFD simulation is to set up the geometry of the problem. In this case, we will be simulating the flow over a 2D airfoil. The geometry can be created using a CAD software and imported into CFD Suite. Alternatively, CFD Suite also provides basic geometric tools that can be used to create simple shapes.
Step 2: Mesh Generation
Once the geometry is set up, the next step is to generate a mesh. A mesh is a grid of points that covers the geometry and is used to discretize the fluid domain. CFD Suite offers various meshing algorithms that can be used to generate a high-quality mesh for the simulation.
Step 3: Set up the Physics
After the mesh is generated, the next step is to set up the physics of the problem. This includes defining the fluid properties, boundary conditions, and any other relevant physical parameters. In the case of external flow simulation, the boundary conditions may include the velocity at the inlet, pressure at the outlet, and no-slip condition at the walls.
Step 4: Set up the Solver
Once the physics is set up, the next step is to select a solver. CFD Suite offers a variety of solvers that can be used for different types of problems. For external flow simulations, the incompressible flow solver is commonly used. The solver settings, such as the time step size and convergence criteria, can also be adjusted at this stage.
Step 5: Running the Simulation
With all the setup complete, the simulation can now be run. The simulation will progress iteratively, with the solver solving the governing equations at each time step. The progress of the simulation can be monitored in real-time using CFD Suite’s visualization tools.
Step 6: Post-Processing
Once the simulation is complete, the results can be post-processed to analyze the flow behavior. CFD Suite offers a variety of post-processing tools that can be used to visualize the flow field, calculate forces and pressures, and extract other relevant data. This information can be used to draw insights and make informed decisions about the design.
In conclusion, this tutorial has provided a brief overview of how to simulate a 2D external flow using CFD Suite. The step-by-step instructions covered setting up the geometry, generating a mesh, setting up the physics, selecting a solver, running the simulation, and post-processing the results. By following these steps, users can quickly and efficiently conduct external flow simulations using CFD Suite.
