comp1810 said:hi i am new to fluent and i hav done few basic tutorials in fluent.But now i need to use dynamic meshing for my project so can anyone guide me how should i start to learn dynamic meshing.
thanxxxxxxxxxxxxxx in advance
Dynamic meshing in Fluent is a feature that allows for the automatic re-meshing of a computational fluid dynamics (CFD) model during the simulation. This means that the mesh or grid used to define the geometry is adapted and refined as the simulation progresses, allowing for more accurate and efficient results.
The main benefits of using dynamic meshing in Fluent are improved accuracy and efficiency. By automatically adapting the mesh, the simulation can capture the flow behavior more accurately and with fewer computational resources. This is especially useful for simulations with complex and dynamic geometries or flow patterns.
Dynamic meshing in Fluent works by using a combination of predefined rules and user-defined criteria to determine when and how the mesh should be adapted. This can include changing the size, shape, and orientation of mesh elements, as well as adding or removing elements in certain areas of the model.
While dynamic meshing can be used with a wide range of simulations in Fluent, it is most commonly used for simulations involving fluid flow and heat transfer. It may not be suitable for simulations with highly non-linear behavior or complex material properties.
One potential limitation of dynamic meshing in Fluent is that it may require more computational resources and time to run compared to simulations without dynamic meshing. Additionally, the automatic mesh adaptation may not always produce the most optimal or accurate results, so it is important to carefully monitor and adjust the simulation as needed.
