TUTORIAL Free Surface - CFD Simulation.In this Build your Simulation CFD IQ! webinar, Jon Wilde and Royce Abel from the Autodesk Technical Support team present on how to solve. Applications Engineer Gordon Stewart presents 'Free Surfaces in Flow Simulation'.Computational fluid dynamics CFD is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid. The vortex method is a grid-free technique for the simulation of turbulent.Re about free surface and make sea wave The parameters used in the harmonic velocity function should be chosen such that they represent the expected wave frequency. Using B = 3 means that the wave period is 2 pi / 3 = 2.09 secoonds which is too quick for waves on this scale.

This might be a meshing issue and not related to free surface. Set it up as simple steady state flow with no free surface and see if it runs. Marwan.Free Surfaces with Level Set, Phase Field, and Moving Mesh A Comparison. We present the results from a comparison of the level set, phase field, and moving.Where there is a free surface, CFD will require an excellent mesh to be able to capture it - typically we use a uniform mesh;.

However, there are some limitations in the simulation model.The Free Surface model does not simulate the following applications: At the start of this example, the reservoir on the left is full, and the one on the right is empty.The reservoirs are separated by a retaining wall with a gate cut-out to allow water to pass between the reservoirs. Geometry: The two reservoirs and the pass-through gate were created as separate parts in the CAD system. Boundary Conditions: There are no inlets or outlets because the flow is contained within the domain. Note that a pressure condition is automatically applied at the liquid-air interface, so it is not necessary to apply an additional pressure boundary condition in this model.Initial Conditions: Because the reservoir on the left starts full of water, apply the HOF initial condition to it.Mesh Sizing: Use Automatic Sizing, but refine the mesh where the air and water will interact.In this case, that is primarily in the gate and in the right-side reservoir.

Currently, Surface Wrap meshes are appropriate for external flow analyses or wind tunnel type models.Without the proper tools and applications, engineers risk making design decisions based on faulty assumptions or inaccurate process simulation data.This could lead to inefficiencies such as decreased production, increased operation costs and poor asset performance. This 60-minute program will be packed with techniques used in the simulation of multiphase flow to understand, predict, and optimize chemical processes.COMSOL expert and Chief Technology Officer, Ed Fontes will discuss the theory behind multiphase flow to give insight into the physics, mathematical models and how to efficiently solve them using numerical simulation software.This webinar will also feature a demo utilizing real-world examples within the COMSOL Multiphysics® software environment.

You Will Learn: Ed Fontes is the Chief Technology Officer at COMSOL.He has been with COMSOL since 1999, and was previously the lead developer for the CFD, heat transfer, and chemical engineering products.He received his Ph D in chemical engineering from the Royal Institute of Technology, Stockholm.

An example of sloshing is the carrying of a dog bowl full of water, in which the liquid has the tendency to slop from side to side and often spill.A multiphase simulation of this free surface flow reveals that this behavior occurs because the first sloshing mode of the bowl is roughly at 2 Hz — the typical human step frequency that excites this undesired resonance.Repeating the analysis for a glass of water reveals a first sloshing mode of 4 Hz, which shows why water glasses are much less prone to spilling than bowls.
