7 Creating and Editing Solid Geometry.docx

1、7 Creating and Editing Solid GeometryNavigation: HyperMesh HyperMesh Tutorials GeometryCreating and Editing Solid Geometry - HM-2060 In this tutorial, you will learn:What solid geometry isWhat topology isWhat 3-D topology looks likeSolids are geometric entities that define a three-dimensional volume

2、. Geometric entities are defined as follows:Point: 0 dimensional; has only x, y, and z coordinatesLine: one-dimensional; has length, can be curved through three-dimensional spaceSurface: two-dimensional; has an areaSolid: three-dimensional, has a volumeThe use of solid geometry is helpful when divid

3、ing a part into multiple volumes. For example, divide a part into simple, mappable regions to hex mesh the part.Exercise: Creating and editing solid geometryThis exercise uses the model file, solid_geom.hm.Step 1: Retrieve model file, solid_geom.hm.Access the Files panel in one of the following ways

4、:From the File menu, select OpenOn the toolbar, click the files icon, Step 2: Create solid geometry from the bounding surfaces.1.From the Geom page, enter the solids panel.2.Verify that you are in the bounding surfs sub-panel.3.Verify that the auto select solid surfaces option is checked.4.Select on

5、e surface on the part.5.All of the surfaces should automatically be selected.6.Click create to create the solid.7.The status bar indicates that a solid has been created. The solids are identified by thicker lines than surfaces.8.Click return to return to the main menu.Step 3: Create a solid geometry

6、 cylinder using primitives.1.Go to the primitives panel in one of the following ways:From the Geometry menu, point to Create, and click PrimitivesFrom the Geom page, go to primitives2.Go to the cylinder/cone sub-panel.3.Toggle full cone to full cylinder.4.Click bottom center, and select one of the t

7、emporary nodes (see following image).5.The cursor automatically advances to the normal vector button.6.Select the remaining temporary node shown in the image.7.For base radius= enter 1.5.8.For height= enter 25.9.Click create solid.A solid cylinder is created in the middle of the first solid that was

8、 created.10.Click return to return to the main menu.Step 4: Subtract the cylinders volume from the rest of the part.1.Enter the solid edit panel in one of the following ways:From the Geometry menu, point to Edit, and click SolidsFrom the Geom page, go to solid edit2.Go to the boolean sub-panel.3.Ver

9、ify that operation type: is set to simple (combine all).4.Set operation: to A-B (remove B from A).5.With the solids entity selector for A: active, select the original solid.Verify that the cursor advances to solids next to B:.6.Select the solid cylinder created in step 3.7.Click calculate.8.To confi

10、rm the material has been removed, click shaded, , and rotate the model to inspect the part.Step 5: Split the solid geometry using bounding lines.You should still be in the solid edit panel.1.Go to the trim with lines sub-panel.2.Under with bounding lines:, activate the solids entity selector, and cl

11、ick anywhere on the model to select it.3.Activate the lines entity selector and, in the graphics area, select the lines shown in the following image.4.Click trim to trim the model.A plane was trimmed. Note that two solids now intersect.Step 6: Split the solid geometry using a cut line.You should sti

12、ll be in the solid edit panel, trim with lines sub-panel.1.Under with cut line:, activate the solids entity selector, and select the small, tetrahedral shaped solid created in step 5.2.On the toolbar, click User Views ().3.From the pop-up window, click restore1.4.Click drag a cut line.5.Pick two loc

13、ations on screen such that they define the endpoints of a line that roughly divides the tetrahedral solid in half, as shown, following.6.Click the middle-mouse button to split the solid.7.Select the half of the original tetrahedral solid as shown in the following image.8.Use with cut line: to split

14、the solid as shown in the following image.9.Select the solid shown in the following image.10.Click User Views () and select restore2.11.Use with cut line: to split the solid as shown in the following image.Step 7: Merge solids together.You should still be in the solid edit panel.1.Go to the merge su

15、b-panel.2.With the solids entity selector under to be merged: active, select the three solids shown in the following image.3.Click merge to merge the solids.The resulting solids in the tetrahedral area should look like the following image. There should be two solid entities, with one of them being h

16、exahedral in shape in the corner.Step 8: Split the solid geometry with a user-defined plane.You should still be in the solid edit panel.1.Go to the trim with plane/surf sub-panel.2.Click User Views () and click restore3.3.With the solids entity selector under with plane: active, select the large sol

17、id representing the majority of the part.4.Set the plane selector to N1, N2, N3.5.With N1 active, press and hold the left mouse button, and move the mouse cursor over one of the two edges shown in the following image.The edge should highlight.6.Release the mouse button, and left-click in the middle

18、of the edge.A green temp node appears at the location to indicate the selection for N1.The plane selector is advanced to the N2 selection.7.In the same manner, highlight the other line shown in the image and select two nodes along its length.Your selection should look similar to the following image.

19、8.Click trim to trim the solid.Step 9: Split the solid geometry with a swept line.You should still be in the solid edit panel.1.Go to the trim with lines sub-panel.2.With the solids entity selector under with sweep lines: active, select the solid with the cylinder removed.3.Activate the line list en

20、tity selector and select the edges used in step 8 to define N1, N2, and N3.4.Under sweep to:, switch the plane selector from N1, N2, N3 to x-axis.5.Verify that the panel is set to sweep all below the plane selector.6.Click trim to trim the solid.Step 10: Split the solid geometry with a principal pla

21、ne.You should still be in the solid edit panel.1.Go to the trim with plane/surf sub-panel.2.With the solids entity selector under with plane: active, select the solid with the cylinder removed.3.Switch the plane selector from N1, N2, N3 to z-axis.4.Press and hold the left mouse button, and move the

22、mouse cursor over the edge shown in the following image.The edge should highlight.5.Release the mouse button, and left-click anywhere along the edge.6.A purple temp node appears at the location to indicate the selection for the base node.7.Click trim to trim the solid.8.Click return to return to the

23、 main menu.Step 11: Split the solid geometry by creating surfaces inside the solids.1.Enter the surfaces panel in one of the following ways:From the Geometry menu, point to Create, and click SurfacesFrom the Geom page, go to surfaces2.Go to the spline/filler sub-panel.3.Deactivate auto create(free e
