An Introduction to ANSYS CFX
This is the first set of tutorials for ANSYS-CFX software. The software provides researchers with flow visualization tools in the virtual environment. ANSYS-CFX is a user friendly software with lots of emphasis on interface tools to distance the researcher from programming as much as possible. It is also provided with a visualization package that is very powerful with its provided built in functions.
Usually users have difficulty in knowing what software to use for what engineering challenge they face. ANSYS-CFX can be applied for subsonic flows which apply for flow problems have a Mach number equal or less than 1. Once your flow simulation is sonic, supersonic, ultra-sonic then you need to use a different type of solver for the purpose of capturing shock waves.
People get mixed up when using ANSYS they think it's only composed of one package, as a matter of fact its composed of several packages one of them is called ANSYS CFX and the other called ANSYS FLUENT.
ANSYS CFX and ANSYS FLUENT use different mathematical models to solve the flow problem. These problems give results but when the user uses them without knowing the numerical models used it would be difficult for him to know that the obtained results are correct or not and how accurate they are. I like to use ANSYS CFX because it is user friendly and its interface is excellent. I don't like to use Fluent because I don't find it easy to use, but in some aspects it can solve problems that are more complex than CFX. I advice you to use ANSYS CFX.
Ready Geometry for Flow Simulation
These ready meshes can help the researcher run simulations where his focus will be on learning how to construct the problem instead of learning the Meshing package provided with the software. The researcher can experiment with these meshes in accordance to the field of interest. These meshes have already been used and have been verified that have no bugs.
