Làm chủ phân tích CFD với ANSYS Fluent

In engineering analysis, the CAD model plays an important role. It may have errors like merged faces, duplicate curves, extra edges, split edges, gaps, or even interference errors. Therefore, we need to avoid dirty CAD geometry, which needs to be repaired and converted to error free geometry. To avoid modeling errors, it is important to select the correct physical models. The most important model for fluid dynamics is a set of partial differential equations called the Navier-Stokes equations.

After getting error-free, correct geometry, we need to go for discretization or meshing. To have an accurate result, we need to focus on better meshing quality because the better the mesh, the better the solution. To minimize the discretization error, we need to go on meshing and remeshing again and again till we reach the minimum error. When we get the exact solution, we say that the convergence criteria have been met.

From this theoretical understanding, we can realize that in FEA, CFD, or any kind of Engineering analysis, meshing or discretization play a very important role. Sometimes the geometry or the CAD model may have some intersecting solids or surfaces. It may have errors like merged faces, duplicate curves, extra edges, split edges, gaps, or even interference errors. In these cases, we cannot go for perfect meshing. Therefore, we need to rectify those errors using the ANSYS space-claim repair tool, and even then, we can share topology. So, if we require perfect meshing, and after that, if we want to go for different types of analysis like structural or CFD analysis, we must say that ANSYS is the best software. Here, to have perfect meshing, we can adopt different meshing methods like watertight geometry and fault tolerant meshing, which are new to the ANSYS interface and have been introduced in the ANSYS 2021 version. Therefore, to be familiar with these new techniques, we have developed this course considering different types of engineering applications with advanced techniques like watertight geometry, fault-tolerant meshing as well as conventional approaches.

Accordingly, we have categorized this CFD course into three different units consisting of twenty videos relevant to industrial applications.

The first unit comprises ANSYS Fluent Fault-Tolerant Meshing, consisting of ten videos.

The second unit comprises ANSYS Fluent watertight geometry, consisting of four videos, and the third unit contains four videos with the conventional approach of CFD Fluent flow analysis.
