How to... define monitors (report definitions) in Ansys Fluent

 There is often a situation when, after completing the analysis and obtaining a satisfactory level of partial equations, we may be unpleasantly surprised when we for example plot the  temperature in the RESULTS module.

How to... move global coordinate systems (reference frames) to axis of rotation Ansys Fluent

An important element of each CFD and structural simulation is the precise definition of the global coordinate system. An improperly located coordinate system can lead to many difficulties - primarily in analyzes where the movement of individual elements is defined.

How to... increase /decrease time step size in Ansys Fluent

 Today I would like to show you how easy it is to control the  analysis in Fluent. All the necessary items can be found in the solver under Run Calculation menu. This is where the coefficients can be modified on an ongoing basis so that our residual equations are at the required level.

How to... define precision of simulation and the criterion of convergence Ansys Fluent

 An important step in modeling is to define the precision of calculations and the criterion of convergence.

How to... define motion in Ansys Fluent - sliding mesh

 In many problems that we want to model, we can meet with the movement of one or more elements. This is one of the three methods available from Ansys Fluent. The others are MRF and SRF (multi refernece frame, single reference frame). Sliding mesh is a traffic definition method for transient analyzes. The other methods can be used both in static and transient. They will be described in more detail in the following entries. In this post we will try to show you how to use the sliding mesh method.

How to... fix "gui-domain-label: no domain selected" in Ansys Fluent and MEMERR in CFX

In today's post, we will deal with another error that may occur during the analysis. The error that is described below concerns Fluent and the wrong definition of user monitors that are displayed during simulation. These can be monitors concerning the average velocity in the domain volume, the values of the maximum temperatures of the solid domains, the average values of the heat transfer coefficient from the defined planes of the model, etc. Generally speaking, today's entry is about how to correctly define monitors and how to transfer them between subsequent analyzes.

How to... correctly mesh CFD model in Ansys CFX and Fluent

Meshing is one of the decisive steps in both CFD and FEA analysis. The correct execution of the mesh and optimization in terms of the number of finite elements makes the work of every Ansys user much easier.
