Nowadays, most of the complicated CAE calculations and deep learning are done with the GPU. In Ansys software it is possible to use the computing power of graphic cards in Fluent and Ansys Mechanical. In this post I will show you how to enable GPU acceleration in Transient and Static Thermal.

A common problem in numerical modeling is the correct export of the output data and their processing. Today I would like to show you how to export data for Point Cloud from several time steps of transient analysis. This guideline applies to both Fluent and CFX.

In the previous post, I showed how to define and load an input table into any boundary condition in Fluent. Today I would like to show you the simplified transient table data definition path for Ansys CFX. As far as the procedure comparison itself is concerned, it seems that the definition of tables in CFX compared to Fluent is easier and more intuitive.

It often happens in CFD modeling that our boundary conditions change over time. Then there is a need to make the input variable dependent on time. For example, on Inlet, we want the gas temperature to increase over time in the transient analysis. For this type of simulation, a very useful option in Fluent is to define transient table data.

Often, in CFD analysis modeling, we deal with more than one gas. Then in Ansys Fluent we follow the path of modeling using Multiphase. This is the right path when we need to define phase transitions. However, if we want to model a simple analysis with two gases that do not interact significantly with each other, then we can use the Species model (figure below).

An important part of numerical modeling is defining the optimal recording of the output. In Ansys Fluent, the Calculation Acitivities option is used for this. We can define many expanded functions in this option. In this post I will try to present a few of them.

For every engineer (constructor or FEA analysis), an important element of work is the definition and selection of materials.For the FEA engineer for the correct and complete definition of the model, for the designer, the selection of appropriate materials that meet the criteria.
