The making of the meshing model using ANSYS
09/01/2023
You want to build a house but before that, you need a blueprint of the house so that you can build it just the way you want. In the paper blueprint, you may not understand it totally but in the 3D blueprint, you can see every corner of the house and also change it just the way you want. Well, this is what ANSYS is. In this blog, we will know the steps to make the meshing model using ANSYS. But before that, let us know a little bit about ANSYS and the meshing model so that we can understand the later part of the blog.
ANSYS is a simulation software that is used to solve a wide range of engineering problems across multiple disciplines, including structural, fluid dynamics, electromagnetic, and thermal analysis. The software can simulate the behaviour of a system under various conditions and can be used to optimise the design of a product or process.
ANSYS provides a wide range of capabilities, such as Finite Element Analysis (FEA), Computational Fluid Dynamics (CFD), and Multiphysics simulation. FEA is used to analyse the structural integrity of a design and can predict how a product will respond to stress, vibration, and other loads. CFD is used to simulate the behaviour of fluids and gases and can predict things like flow patterns, heat transfer, and chemical reactions. Multiphysics simulation allows to couple the of different physics in the same simulation such as thermal-structural, electro-magnetic-structural and so on.
ANSYS can be used in a variety of industries, including aerospace and defence, automotive, electronics, energy, and healthcare. It is widely used by engineers, researchers, and scientists to design, analyse and optimise products, processes and equipment. ANSYS also provides a wide range of pre-processing and post-processing tools that can be used to prepare models, visualise results, and extract data. It also offers many add-ons and specialised software for specific industries and applications.
Identifying the meshing model
Meshing is the process of dividing a model into smaller, simpler shapes called “elements” that can be analysed numerically. This process is also known as “discretization.” The resulting mesh is a collection of interconnected elements that represent the model’s geometry and topology.
In many simulation software like ANSYS, the meshing process is critical to the accuracy and quality of the simulation results. A good mesh will ensure that the solution is accurate, stable, and efficient, while a poor mesh can lead to errors, instability, and slow convergence.
There are different types of meshing techniques, such as structured, unstructured, and hybrid meshes. Structured meshes are composed of simple, regular shapes like squares or hexagons and are often used in CFD analysis. Unstructured meshes are composed of more complex, irregular shapes and are often used in FEA analysis. Hybrid meshes combine both structured and unstructured elements and can be used in multiphysics simulations.
The selection of the mesh type and element size will depend on the simulation type, the complexity of the geometry, and the accuracy required. Meshing can be done automatically or manually, depending on the simulation software and the user’s preference. Many software’s like ANSYS offers both options.
Making the meshing model using ANSYS
Creating a meshing model in ANSYS involves several steps, which can be broadly grouped into three categories: geometry preparation, meshing, and post-processing.
Geometry Preparation: This step involves importing or creating the model geometry in ANSYS. The geometry can be imported from a variety of file formats, such as IGES, STEP, or SolidWorks. Once the geometry is imported, it should be cleaned up and prepared for meshing. This can include tasks such as removing unnecessary details, applying symmetry, or applying boundary conditions.
Meshing: Once the geometry is prepared, the next step is to create the mesh. ANSYS provides several meshing tools, including the ANSYS Meshing application, which can be used to create structured, unstructured, or hybrid meshes. The user can select the type of elements, element size, and other meshing parameters depending on the simulation type and the accuracy required.
Post-processing: After meshing, the user can use ANSYS’s post-processing tools to check the quality of the mesh, and make any necessary adjustments. This can include tasks such as checking for element quality, checking for element distortion, and checking for element skewness.
It’s worth noting that the above steps are a general guide and depending on the specific simulation type, there may be additional steps or variations. The user can also benefit from ANSYS tutorials and documentation for a more detailed understanding.
