Structures Structural Analysis ANSYS structural analysis software enables you to solve complex structural engineering problems and make better, faster design decisions. With the finite element analysis FEA tools available in the suite, you can customize and automate solutions for your structural mechanics problems and parameterize them to analyze multiple design scenarios.
Notice that the elements are well shaped, but that elements are required to fill the area since the elements are uniformly sized. The model is made of a single area.
Some of the elements of this mesh, however, have poor aspect ratios for example, those around the small holes. Another weakness of mesh b is that the elements change in size transition from the small elements to the larger elements, especially near the small holes.
This mesh has far fewer elements than mesh a of Figureyet the transition from small elements to larger elements is fairly smooth.
Also, the element aspect ratios are significantly better than the elements in mesh b of Figure Note-Quadrilateral surface meshes will differ based on which triangle surface mesher is selected.
This is true because all free quadrilateral meshing algorithms use a triangle mesh as a starting point. References to the Mesher Options dialog box appear throughout this section Section 7.
Surface Meshing Options The following options for triangle surface meshing are available: This is the recommended setting and the default. If the chosen mesher fails for any reason, ANSYS invokes the alternate mesher and re-tries the meshing operation.
Main triangle surface mesher Riemann space mesher. ANSYS uses the main mesher, and it does not invoke an alternate mesher if the main mesher fails. The Riemann space mesher is well suited for most surfaces. First alternate triangle surface mesher 3-D tri mesher. ANSYS uses the first alternate triangle mesher, and it does not invoke another mesher if this mesher fails.
This option is not recommended due to speed considerations. However, for surfaces with degeneracies in parametric space, this mesher often provides the best results.
Second alternate triangle surface mesher 2-D parametric space mesher. ANSYS uses the second alternate triangle mesher, and it does not invoke another mesher if this mesher fails.
This option is not recommended for use on surfaces with degeneracies spheres, cones, and so on or on poorly parameterized surfaces because poor meshes may be created.
The options listed below are available for quadrilateral surface meshing. Keep in mind that quadrilateral surface meshes will differ based on which triangle surface mesher is selected.
If either mesher fails for any reason, ANSYS invokes the other mesher and re-tries the meshing operation. Main quadrilateral surface mesher Q-Morph mesher. ANSYS uses the main mesher, and it does not invoke the alternate mesher if the main mesher fails.
In most cases, the Q-Morph mesher results in higher quality elements see Figure The Q-Morph mesher is particularly beneficial to users whose applications require boundary sensitive, highly regular nodes and elements.
Figure Mesh a shows a surface that was meshed with the alternate quadrilateral mesher; mesh b shows the same surface, this time meshed with the Q-Morph mesher.ANSYS Fluent software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications—ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants.
Ansys has the function GET and VGET to do something, but it does not have the ability (to return an array including the node numbers of a line). ANSYS Mechanical – Introduction to Contact C.

The program ANSYS Workbench platform has also been found in our database for this reason. The following tables provide information about the association of the program ANSYS Workbench platform with file extensions. If the program ANSYS Workbench platform can be used to convert the data, such information will also be provided.
