This tutorial is the beginners guide to understand basics of meshing techniques and implement meshing methods on models with the help of powerful tools like Hypermesh from Altair. With the broadest set of direct interfaces to commercial CAD and CAE systems, HyperMesh provides a proven, consistent analysis platform for the entire enterprise. With a focus on engineering productivity, HyperMesh is the user-preferred environment for: Solid Geometry Modeling 3D Visualization of all element types 1D, 2D and 3D elements within a FEA model eases model checking and visual verification. Using sophisticated batch meshing technology, HyperMesh eliminates the need to perform manual geometry clean-up and meshing, thus accelerating the model development process. Delivering the most powerful model morphing tool in the industry HyperMesh allows users to modify existing meshes to meet new designs and reduce model development costs. Detailed Model Setup Generating surfaces from finite element models enables analysis engineers to easily communicate and share product modifications with design teams.

It is recommended to review the general overview before completing this tutorial. Step 1: Retrieve the model file, bumper. Go to the create sub-panel. Use the drop down arrow to select components. Create the component collector geometry. The message: "The collector was created", appears in the header bar.
Left click once anywhere in the HyperMesh window, except on a button to dismiss the message in the header bar.
The component geometry is now the current component. Any geometry or elements that are created will be organized into this component. Return to the main menu. Step 3: Create two geometry lines and organize them into different components.
Go to the from nodes sub-panel. Altair Engineering HyperMesh Tutorials 8. With the node list selector active, select two nodes, opposite and diagonal to each other, on the same element as indicated in the image below. Create the line. Notice the line is yellow, the same color assigned to the component, geometry. This is because the line is organized into the current component, geometry. On the toolbar, click on comp to view current collectors. Click comp and select the component, rigid, from the list of components in the model.
The panel now shows comp rigid. Also, the header bar shows comp: rigid. With the node list selector active, select two nodes, opposite and diagonal to each other on another element. Notice the line is dark pink, the same color assigned to the component, rigid. This is because the line is organized into the current component, rigid. Switch the entity selector to surfs. Displayed surfaces are highlighted in white indicating they are selected. Select geometry from the list.
Move the selected surfaces into the component, geometry. You should still be in the organize panel. Switch the entity selector to elems. Select the components, mid1, mid2, and end. Select a component by left clicking its name, color, or check box. A component is selected when it has a check in its check box. To unselect a component, right click on it. Click select to complete the selection of components. Move the elements in the selected components to the component, center.
All of the shell elements should now be a cyan blue, the same color assigned to the component, center. Step 6: Rename the component, center to shells.
Go to the individually sub-panel. Verify the entity type is set to comps. Type shells. Step 7: Identify and delete all of the empty components. Switch the entity selector to comps. Click preview empty. The header bar displays the message: "3 entities are empty. Click the entity selector comps once to see a list of the identified empty components. The empty components are indicated with an activated check box.
Return to the delete panel. Click delete entity. The header bar displays the message, "Deleted 3 comps". Step 8: Delete all the geometry lines in the model. You should still be in the delete panel. Switch the entity selector to lines. The two lines you created earlier are deleted.
Step 9: Move the component, geometry, to the front in the components list. On the right side of the panel, click the switch and select name id. Switch from name to name id. Notice the IDs of the components. Select the component, geometry. Click select to complete the selection. Activate the option move to: front. Reorder the component, geometry. The header bar displays the message, "The selected collectors have been moved. Click the comps selector once to review the reordered list of components.
Notice the component, geometry, is at the top of the list. However, it still has the same ID, six. Step Renumber the components to be the same as their position in the list. Go to the single sub-panel. Renumber the components. Notice the components are numbered according to their position in the list.
Step Create an assembly containing the components, shells and rigid. Select the components shells and rigid. Create the assembly. Step Create a load collector named constraints. Use the drop down arrow to select load collectors. Create the load collector. The header bar displays the message: "The collector was created". Left click anywhere in the HyperMesh window except on a button to dismiss the message in the header bar. Click comp: in the toolbar. Notice that loadcol constraints appears in the popup.
Now, the current load collector is constraints. Any loads that are created will be organized into this load collector. The existing load collector, loads, contains several forces and one constraint. The organize panel is used to move the one constraint in the load collector, constraints. Switch the entity selector to loads.
Toggle from displayed to all. Click select entities. Move the select loads constraints into the load collector, constraints.
Or go to the View menu, select Model Browser. Step Create a component from the model browser. Right -click in the white blank area below the list of components, materials, load collectors, and system collectors in the model browser. Click Create to create the component. The component, named component1 is appended to the list.
Step Review the existing assembly elements from the model browser. Notice that it contains two components, rigid and shells. Note that the assemblies panel allows you to add components, which are in one assembly to another assembly. The model browser does not allow you to do this, but you can create assemblies from it.
Left click on the component name, geometry, to select it. Press the Ctrl key and left click on the component name, component1.
A combination of lectures and exercises will familiarize students with the HyperMesh environment, process, and suite of tools needed to start using HyperMesh in their work. The solution identifies part intersections, missing welds and incorrect bolt-nut positions on an entire assembly structure and generates comprehensive reports. Videos, Webinars HyperMesh Quickstart v The purpose of this self paced course is to introduce HyperMesh to new users of the software. Most sections will use the See It, Do It methodology to cover the concepts.
It is recommended to review the general overview before completing this tutorial. Step 1: Retrieve the model file, bumper. Go to the create sub-panel. Use the drop down arrow to select components.

The sessions aim to upgrade and improve your skills in key aspects of Data Analytics — Data Preparation, Machine Learning and Visualization. In automotive engineering and simulation, it is becoming more and more challenging to handle large size 3D models with a high level of detail. This is especially true when sharing 3D models between OEMs and suppliers in the design stage, as well as utilization in downstream processes and manufacturing required file size reduction for sufficient performance and IP Intellectual Property protection while maintaining the initial design intent. Simplification accelerates the creation of simulation models.
