  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

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

 The error message Error: GENERAL-CAR-CDR: invalid argument [1]: improper list means that there is a problem with the scheme code or the UDF (user-defined function) in your case or data file . Some possible solutions are: Save the case and data file and try to reopen it. Reset the Fluent Setup tab and try opening the mesh. Remesh the geometry and reopen in Fluent. Change the material definition from “Solid” to “Fluid” in Design Modeler. Change the transient to steady if you are using evaporation-condensation as the phase interaction mechanism. Check the syntax of your UDF and make sure it follows the new rules in Fluent 6.2.16 or later. I hope this helps you resolve the error.
