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

Supports are used to represent parts that are not present in the model but are interacting with it. Supports help truncate the domain, which helps in efficiently obtaining numerically accurate results without modeling parts of the geometry that are not of primary interest. There are different types of support available, among which you need to choose the appropriate one for your analysis. Here are some of the common types of supports and their explanations: - **Fixed Support**: This type of support constrains all the degrees of freedom of the selected entity (body, face, or edge). It means that the entity cannot move or rotate in any direction. Fixed support is equivalent to applying zero displacement to all directions. Fixed support is useful for modeling rigid connections or supports that do not allow any movement. For example, you can use fixed support to model a bolted joint or a clamped beam. - **Displacement Support**: This type of support specifies a zero or non-zero displacemen

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 

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

  SU2 (cfd) is a suite of open-source software tools for the analysis of partial differential equations (PDEs) and PDE-constrained optimization problems on unstructured meshes with state-of-the-art numerical methods 1 . The primary applications are computational fluid dynamics and aerodynamic shape optimization, but it has been extended to treat more general equations such as heat transfer, electromagnetics, elasticity, and turbulence modeling 2 . SU2 is written in C++ and Python and can be downloaded from its website or GitHub repository . SU2 is also used for research and education in the engineering sciences 1 . Some additional sentences are: SU2 is developed and maintained by a worldwide community of individuals and organizations who share a common vision of advancing the field of multiphysics simulation and design 1 . SU2 offers a range of features and capabilities, such as discrete adjoints, non-ideal compressible CFD, high-performance computing, incompressible flows with heat t
