Types of fluid flow in CFD analysis

In today's post, I would like to introduce you to the theory of turbulence. It is important to know the basic issues of fluid mechanics because thanks to this we are able to verify our assumptions and simulation results.

Tips to deal with OVERFLOW error in Ansys CFD

 You've often wondered what could be the reason why your simulation crashes and an overflow error pops up. Today I would like to introduce you  seven tips on what could be causing this error and how to deal with it.

How to... define user variable in Ansys Postprocessing

Very often we need to define a given area / zone / separated fragment with one variable. For example, it could be the average temperature of the model's cross-section as a function of time. For this type of operation, the function of defining your own variables from the level of postprocessing is very useful.

How to... define Table in material properties - Piecewise Linear in Ansys Fluent

 An important element of the analysis is the ability to define variable material properties depending, for example, on temperature. The Ansys Fluent program offers many options that will allow us to model the material in this way. One such feature is Piecewise Linear.
