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 

  Joint boundary condition is a type of connection element that allows you to model the relative motion and interaction between two or more bodies in a structural analysis. Joint boundary condition can be used to simulate various types of joints, such as revolute, cylindrical, spherical, planar, slot, universal, and fixed joints. Joint boundary condition can also be used to apply loads and moments to the connected bodies. To use joint boundary condition in Ansys Static Structural, you need to follow these steps: In the Model tree, right-click Connections and select Insert > Joint. In the Details view, select the type of joint you want to create from the drop-down list. In the Geometry section, select the two or more bodies that you want to connect with the joint. You can also specify the location and orientation of the joint coordinate system (JCS) using the options available. In the Definition section, specify the degrees of freedom (DOF) that you want to allow or restrict for the

PrePoMax is a freeware pre- and postprocessor for open-source Finite Element Analysis solver CalculiX 1 . It offers a user-friendly GUI and supports many features provided by the CalculiX solver. To model in PrePoMax, you need to follow these general steps: Create or import a geometry using the Geometry menu 2 . Generate a mesh using the Mesh menu 2 . Define the FE model using the Model , Property , Interaction , Initial Condition , and Step menus 2 . Export the input file for CalculiX using the File menu 2 . Run the analysis using the Tools menu 2 . Import the results file and visualize the output using the View menu 2 . You can find more detailed instructions and examples in the PrePoMax documentation 1 and video tutorials 1 . I hope this helps you get started with PrePoMax. 😊 The official PrePoMax website 1 has a section on documentation, where you can download the PrePoMax manual in PDF format. The manual covers the basic features and workflow of PrePoMax, as well as some
