How to... export report definitions to Excel or any other spreadsheet from Fluent

In today's post I would like to show you how to easily and quickly export data from Report Definitions about your defined monitors in Ansys Fluent.

Radiator Game - Episode 1 - CHT in Fluent

In today's post and a few more, I will introduce you to the FEA modeling of CHT analysis in Fluent, a very common phenomenon, which is heating a room with a radiator. In the first part, we will determine the heat losses on the walls of the building with very simple dependencies and we will perform a preliminary CHT analysis of heating the room with a radiator.

How to... simulate Bullet in Ansys Fluent Tutorial

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.

CFD Rivals - CHT Analysis - CFX Tutorial Step-By-Step

 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.

CFD Rivals - CHT Analysis - Fluent Tutorial Step-By-Step

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.

CFD Ansys Rivals - CFX vs Fluent in 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.

How to..easy mesh CFD models in Ansys Workbench (size and type of finite element)

 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.
