In today's post, I would like to show you a tutorial on how to model a bullet flight in Ansys Fluent. Due to the earlier post where the bullet was modeled in the SimScale software, it will be an interesting comparison, especially when it comes to gas velocity distributions.

Today I would like to introduce you to the CHT simulation tutorial in CFX. This is the missing link to the previous two entries. In CFX, CHT analysis is defined a bit differently than in Fluent.

As I mentioned in the previous post, in the next one I will deal with a detailed description of the defined analyzes in CFD Ansys programs. First, I will provide a step-by-step tutorial on CHT analysis modeling in Fluent.

| Meshing for Fluent CHT Analysis |
Today I would like to present what differences in the obtained results can be expected in the two leading CFD programs from Ansys. It should be noted that most of the analysis settings (both for CFX and Fluent) remained in the default positions. Especially to test the differences, I chose the type of CHT analysis (conjugate heat transfer), thanks to which it is possible to analyze a wide range of output data.

In many analyzes, we want our mesh not to be too large and at the same time fit into the general rules of CFD discretization. Then it is worth using the definition of the size of the finite elements in the zones of the geometric model that are of interest to us. The Element Size function is used primarily for this type of definition.

When performing numerical analyzes, our models are often incomplete. Then we have to do a few activities consisting in either modifying the existing geometry or adding the missing element. In today's post, I would like to show you how to easily add an additional missing element in Design Modeler.

In an earlier post, I presented how to configure CAE calculations using the GPU in Ansys Mechanical. Today I would like to show you how to configure the use of a graphics card in Ansys Fluent. First of all, you need to correctly configure the proportion of the use of the amount of CPU to GPU depending on the HPC license you have.
