The Story Behind ANSYS Innovation
Most of the tutorials will already have a tetin file called geometry. Some of the tutorials will begin with a 3rd party geometry, e. Commands in succeeding tutorials may be referred to or explained in a previous tutorial. Please read through the introduction before beginning the tutorials.
The user not only learns the sequence of commands, but also comes to understand the concept behind the individual commands. After going through these tutorials, the user will be capable of extending his or her knowledge of the functions into more complicated projects. Each example will either introduce new features or use familiar features in new ways to ultimately achieve better results for specific geometries.
Lessons begin by outlining the functions and operations being introduced in the example. New features will receive the most thorough explanations in the chapter in which they are first introduced. Italicized font indicates a button selection.

This environment can combine CAD surface geometry and triangulated surface data into a single geometry database using the geometry interfaces. All geometry entities, including surfaces, curves and points are tagged or associated to a grouping called a part. With this part association, the user can quickly toggle off or on all entities within the parts, visualize them with a different color, assign mesh sizes on all entities within the part and apply different boundary conditions by part.
Since the CAD geometry is tagged with mesh parameters and boundary conditions directly in this interface, the user can recalculate a mesh reflecting these changes in the geometry immediately after having saved the geometry file.

This allows the user to alter complex geometry or create simple geometry without having to go back to the original CAD. These curves and points will act as constraints for the mesher, forcing nodes and edges of the elements to lie along them, and thus capturing the hard feature. A powerful smoothing algorithm provides the element quality. Options are available to automatically refine and coarsen the mesh both on geometry and within the volume.
A Delaunay algorithm is also included to create tetras from surface mesh that already exists and also to give a smoother transition in the volume element size.
Blocks can be built and interactively adjusted to the underlying CAD geometry. Complex topologies, such as internal or external O-grids can be generated automatically. Compared to pure tetrahedral grids, this results in smaller analysis models, better convergence of the solution and better analysis results.
Hybrid Meshes Hybrid meshes can be created by several means: Tetra and Hexa meshes can be united merged at a common interface in which a layer of pyramids are automatically created at a common interface to make the two mesh types conformal.
Hexa-Core meshes can be generated where the majority of the volume is filled with a Cartesian array of hexahedral elements essentially replacing the tetras. Hexa-Core allows for reduction in number of elements for quicker solver run time and better convergence. Four methods are available: Mapped based shell meshing Autoblock : Internally uses a series of 2d blocks, results in mesh better lined up with geometry curvature.
Gives best quad dominant quality and capturing of surface details. Patch independent shell meshing Patch Independent : Uses the Octree method. Best and most robust on unclean geometry. Shrinkwrap: Used for quick generation of mesh. As it is used as the preview of the mesh, hard features are not captured.
After initial mesh is created by any of the meshing modules, diagnostics can be performed to determine local and overall mesh quality. Automatic smoothing algorithms are in place to improve overall quality. Local editing can be done using a wide range of automatic re-meshing and manual mesh editing tools. It provides an in-depth view of data with visualization tools such as cut planes, stream ribbons, contours, vectors, grids, iso-surfaces, offset surfaces, result surfaces, integration, XY plots, data probes, function calculator, solution and experimental comparison, scripts, annotations and animation.
Results can be interpolated on imported surface meshes and written out to a different solution process, e. A surface manager tool controls the display status for all surfaces, including any dynamic surface, domain surfaces and user-defined surfaces. File The File menu is used to create new or open existing projects, loading and saving files, importing and exporting geometries and initialize scripting.
View Contains various options for the standard view, controls, and annotations. Info This menu allows the user to get various information regarding geometry, mesh and individual entities.

It also includes measurement and setup of local coordinate systems. Depending on the licensing, some users may not be able to access certain meshing modules.
Either a block file must be loaded or an initial block created to make all the items active. A results file from various CFD and structural formats must first be loaded to make this menu active. The tree is organized by categories. Each category can be turned on or off by selecting the check box.
If the check mark is faded, some of the subcategories are turned on and some off. Since some functions are performed only on the entities shown, the model tree is a very important feature to use when isolating the particular entities to be modified. Right mouse selecting a particular category or type will reveal several display and modification options.
Subsets can also be created, displayed and modified. A given entity can belong to more than one subset. Subsets within this category are the same as for Geometry but contain only mesh element types. An entity cannot belong to more than one part. With this association, groups of entities, regardless of type can be toggled on and off.
Parts have a specific color to discern them from other parts. The Message window displays the communicator between the GUI and the geometry and meshing functions.
It is important to keep an eye on the Message window, because it will keep the user informed of the status of operations. Any requested information, such as measure distance, surface area, etc. Also, internal commands can also be typed and invoked within the message window. The Save commands will write all Message window contents to a file. It is important to note that the Log file is unique from the file created with the Save button.
This file will be written to the starting directory, and it interactively updates as more messages are recorded. Once the toggle is turned OFF, you can continue to add to the file by turning the toggle back ON and accepting the same file name which is the default.

It will then continue to append this file. The X axis represents element quality usually normalized to between 0 and 1 and the Y axis represents the number of elements. Other functions which utilize this space will become pop-up menus if the quality or histogram is turned on.
In case UNDO is used after creation of any point, and then a new point is created, the new point will have the next name in series.
For example, if Point05 is created and Undo is used, then the next point created will be named Point Assign coordinates 0 0 0 shown below. Press Apply to create a point. Select Fit Window from the main menu. Use the right mouse button to zoom out if needed.
Now enter the coordinates as shown below, and press Apply after each one. The Display window should now show the points as seen in the figure above. The CoOrdinates of the point will be shown on screen as well as will be visible in the Message Window. Press the middle mouse button to accept the points. The point names will appear in the selection window.

Similarly, select the following points, pressing middle mouse button each time. Press the middle mouse button to accept the point. Press Dismiss to close this window. The geometry after creating the two arcs is shown here. Press the middle mouse button to accept the selection.
Give Gap a Tolerance of 0. Press Dismiss to close the Create Point window. In the dropdown, Segment by Point should be selected. Now select the point selection icon and select POINT01 with the left mouse button and then press the middle mouse button to accept the point.
