When creating geometry, these attributes c an be controlled by specifying the appropriate values in the Part:, Surface: and Layer: fields in the entry dialog. However, if the mesh is modified, the operations performed on the lines will not be altered.)Īs in Superdraw III, each line in Autodesk Simulation has part, surface and layer attributes. (It is important to note that an equivalent model can be created by selecting all of the lines of the mesh and performing the operation on the lines. The advantage over Superdraw III is that the original mesh parameters can be modified later, and any operations that were performed on the mesh will be performed again automatically using the new mesh. ![]() Once an operation is performed, a new heading for the operation will appear in the tree view under the heading for the selected mesh. Even though the move, rotate and scale commands are listed separately, all three of these operations can be performed from within each of these commands by activating the appropriate check boxes. If you need to perform operations on the mesh that are equivalent to the operations available with the Quick RMS command in Superdraw III, select the heading for the mesh in the tree view and select one of the commands. Once a structured mesh is created in Autodesk Simulation, a heading will be created for the mesh in the tree view under the Meshes heading. All of the options provided in Superdraw III will be available. The mesh spacing for all of the mesh types can be modified by pressing the button next to the field for the desired side of the mesh in the Divisions section. After the mesh is created, the sketch entities will still exist to be used as a future reference. The divide 1 object, between 2 objects and 4 object 3D meshes in Autodesk Simulation work with construction objects, not regular mesh lines. In Superdraw III the rectangle would have been replaced by the mesh. Unlike in Superdraw III, the rectangle will still exist for use as a future reference. For example, if you draw a construction rectangle, you will be able to create a 4 point rectangular mesh using the four corners of the rectangle. These points can either be defined by coordinates, by selecting existing vertices in the model or by selecting end points of existing construction objects. The 3 point triangular, 4 point rectangular and 8 point 3D meshes are defined using multiple points. The structured mesh options in Superdraw III are also available in Autodesk Simulation (4 point, between two objects etc.). The advantage provided over Superdraw III is that these construction objects will remain available after they are used to create lines so that they can be used again. Second, structured meshes can be created from construction objects. First the lines can be created directly in the viewing area as they were in Superdraw III (trusses, beams or other line elements). Refer to Creating and Editing Geometry in the FEA Editor: Drawing Planes, Adding Geometry and Meshing Hand-built Models: 2D Mesh Generation, and Creating Contact Pairs.ģD models can be created in Autodesk Simulation using two methods depending on the element type. This allows you to easily adjust the geometry of the model and regenerate the mesh. Simply select the two surfaces where contact is desired, right-click and select the desired contact type from the Contact pull-out menu.Īnother advantage that Autodesk Simulation provides over Superdraw III is that the objects used to create the wireframe will still be available for modifications after the original mesh is generated. Where as Superdraw III is limited to bonded contact between parts in a 2D mesh, Autodesk Simulation can specify different types of contact (bonded, surface contact) between parts of a 2D mesh. To specify how many elements are to be created along an arc or line, right-click the arc or line and select the Divisions command. ![]() You can add refinement points by right-clicking in the sketch and selecting the Add Refinement Point command. (2D elements still need to be created in the YZ plane, as before.)īefore generating the mesh, there are several mesh parameters that you can define. ![]() Once the wireframes are drawn, select all of the drawing plane headings in the tree view, right-click one of the headings and select the Create 2D Mesh command. Also the geometry where two parts meet must be identical in both parts for the meshes to match up. As with Superdraw III, each part within a plane must enclose a single continuous area. This is done using sketches made on drawing planes. Where as Superdraw III is limited to creating automatically generated meshes of 2D models in the YZ plane, planar geometry in any plane can be meshed in the FEA Editor.
