How can I check which element types are used for the calculation and is there a way how to change them mechanically?

You can also change the element order here from linear or quadratic or vice-versa. Now, if you want to get into the details of what element type the code is using you can always right-click on the analysis type, open the solver directory and look into the ds. Different elements can be used for different analysis types depending on compatibility. Once you find the element type read through the manual for more details.

In addition to Sandeep's info, in case you are interested in APDL element type, you should open the ds. ET,matid, e. Note that the element topography must be consistent with the element shapes compatible with that element type.

For instance, you cannot issue SOLID element to a part with midside nodes dropped linear elements or with all tetrahedral elements. Once you have created the mesh, i. If you want to change to a compatible element as Aniket mentions above, you would just have to place a one-line command snippet like he shows. What is your specific case, what mesh do you have and what element type are you trying to change to?

I added the command line but the solution does not converge.

Got an error and a warning. Node was somewhere close to middle of a plate I am simulating - without any boundary conditions assigned. Check the Solution Output to see what elements are actually being used. I'm not sure why. In the example mentioned above I am doing some basic checks with a simply supported Laminated glass [Fig 1].

I applied Sweep for 3 bodies following your instructions, and I did as well edge sizing on the z direction smallest dimension of glass panes [Fig 2]. I will try again at the example with the mould that I attached you on a previous post and I will let you know it goes. Home Leaderboard Activity Badges.

Permalink 0 0 0. Order By: Standard Newest Votes. SandeepMedikonda posted this 01 August Meshing is an integral part of the computer-aided engineering simulation process. The mesh influences the accuracy, convergence and speed of the solution. Furthermore, the time it takes to create and mesh a model is often a significant portion of the time it takes to get results from a CAE solution. Once the best design is found, meshing technologies from ANSYS provide the flexibility to produce meshes that range in complexity from pure hex to highly detailed hybrid; a user can put the right mesh in the right place and ensure that a simulation will accurately validate the physical model.

Otherwise, Tetrahedrons Patch Conforming is used. Reducing the number of midside nodes reduces the number of degrees of freedom. Program Controlled is the default. For surface bodies and beam models, Program Controlled is identical to the Dropped option described below. For solid bodies and 2-D models, Program Controlled is identical to the Kept option described below.

The Dropped option removes midside nodes on all elements. Examples shown below are for a solid body. The Kept option retains midside nodes on elements created in the part or body. All elements will have midside nodes. An algorithm setting is displayed allowing you to choose how the tetrahedral mesh is created based on your choice of one of the following options :. Patch Conforming Method. Faces, edges and proximities are respected and resolved. Patch Independent Method.

Hex Dominant Meshing Methodwhere a free hex dominant mesh is created. The mesh contains a combination of tet and pyramid cells with majority of cell being of hex type. Hex dominant meshing reduced element count.

The mesher will fail if a swept mesh cannot be generated on a body with a sweep method control. It automatically generates a pure haxehedral mesh where possible and then fills the more difficult to capture regions with unstructured mesh.

The MultiZone mesh method and the Sweep mesh method operate similarly; however, MultiZone has capabilities that make it more suitable for a class of problems for which the Sweep method would not work without extensive geometry decomposition.

Subscribe today to take online courses.Meshing is an integral part of the engineering simulation process where complex geometries are divided into simple elements that can be used as discrete local approximations of the larger domain. The mesh influences the accuracy, convergence and speed of the simulation. Furthermore, since meshing typically consumes a significant portion of the time it takes to get simulation results, the better and more automated the meshing tools, the faster and more accurate the solution.

ANSYS provides general purpose, high-performance, automated, intelligent meshing software which produces the most appropriate mesh for accurate, efficient multiphysics solutions — from easy, automatic meshing to highly crafted mesh. Methods available cover the meshing spectrum of high-order to linear elements and fast tetrahedral and polyhedral to high-quality hexahedral and Mosaic.

Geometry of flap is attached. Thank you very much for your kind reply, but what should be done if the body to be selected for 'body of influence' is suppressed in fluent meshing? Yes I have created a surface around a flap image is attached but again I cannot increase mesh resolution just around the flap because flap is suppressed.

Homa has an updated profile.A mesh is a representation of a larger geometric domain by smaller discrete cells. Meshes are commonly used to compute solutions of partial differential equations and render computer graphicsand to analyze geographical and cartographic data.

A mesh partitions space into elements or cells or zones over which the equations can be solved, which then approximates the solution over the larger domain.

Element boundaries may be constrained to lie on internal or external boundaries within a model. Higher-quality better-shaped elements have better numerical properties, where what constitutes a "better" element depends on the general governing equations and the particular solution to the model instance.

There are two types of two-dimensional cell shapes that are commonly used. These are the triangle and the quadrilateral. Computationally poor elements will have sharp internal angles or short edges or both. This cell shape consists of 3 sides and is one of the simplest types of mesh. A triangular surface mesh is always quick and easy to create. It is most common in unstructured grids.

This cell shape is a basic 4 sided one as shown in the figure. It is most common in structured grids. The basic 3-dimensional element are the tetrahedronquadrilateral pyramidtriangular prismand hexahedron. They all have triangular and quadrilateral faces. Extruded 2-dimensional models may be represented entirely by the prisms and hexahedra as extruded triangles and quadrilaterals.

In general, quadrilateral faces in 3-dimensions may not be perfectly planar. A nonplanar quadrilateral face can be considered a thin tetrahedral volume that is shared by two neighboring elements.

A tetrahedron has 4 vertices, 6 edges, and is bounded by 4 triangular faces. In most cases a tetrahedral volume mesh can be generated automatically. A quadrilaterally-based pyramid has 5 vertices, 8 edges, bounded by 4 triangular and 1 quadrilateral face. These are effectively used as transition elements between square and triangular faced elements and other in hybrid meshes and grids.

A triangular prism has 6 vertices, 9 edges, bounded by 2 triangular and 3 quadrilateral faces. The advantage with this type of layer is that it resolves boundary layer efficiently. A hexahedrona topological cubehas 8 vertices, 12 edges, bounded by 6 quadrilateral faces.

It is also called a hex or a brick. The pyramid and triangular prism zones can be considered computationally as degenerate hexahedrons, where some edges have been reduced to zero. Other degenerate forms of a hexahedron may also be represented. A polyhedron dual element has any number of vertices, edges and faces.

It usually requires more computing operations per cell due to the number of neighbours typically Structured grids are identified by regular connectivity.

The possible element choices are quadrilateral in 2D and hexahedra in 3D.
