How To ... ANSYS - Tutorials, Tips and Tricks

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. Example of bad geometry position vs coordiante system 

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. Example of "gui-domain-label" error in Fluent 

Ansys Static Structural is a software that allows you to perform linear and nonlinear static analysis of structures, such as beams, plates, shells, and solids. One of the important aspects of static structural analysis is the contact between different parts of the structure, which can affect the stress, deformation, and load transfer. According to the web search results, there are three main types of contacts in Ansys Static Structural: bonded, frictionless, and frictional¹². Each type of contact has different characteristics and applications, depending on the behavior of the interface between the parts. - Bonded contact: This type of contact assumes that the parts are perfectly attached to each other, and there is no relative motion or separation between them. This means that both the normal and tangential forces are very large and resist any external forces that try to break or slide the parts. Bonded contact is useful for modeling welded joints, adhesive contacts, or some bolted con

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.
