🍾 Element Quality Check In Hypermesh

Three types of element quality checks are performed: Validity check of maximum allowable limits - a bound based on mathematical limitations. Violation will cause singular or ill-conditioned element matrices. Examples are: a re-entrant angle (equal to or greater than 180 degrees) in quadrilateral element/surface, 0 collapse in tetra. BatchMesher is a tool that can perform geometry cleanup and automeshing (in batch mode) for given CAD files. BatchMesher performs a variety of geometry cleanup operations to improve the quality of the mesh created for the selected element size and type. Cleanup operations include: equivalencing of "red" free edges, fixing small surfaces Check Element Quality Use the Check Elems panel, 1D subpanel to: Check one-dimensional elements for free ends Determine if a group of rigid Check one-dimensional elements for free ends Determine if a group of rigid elements form a loop Check weld and rigid elements for double dependency Check all The value of the worst face is reported as the 3D element’s overall quality value. Additional element checks not listed here are not part of the solver’s normal set of checks, and therefore use HyperMesh check methods. Scale the thickness of elements in your model. Restriction: Only available in the LS-DYNA , Radioss and PAM-CRASH 2G solver interfaces. From the menu bar, click Mesh > Edit > Elements > Scale Thickness. The Scale Thickness dialog opens. Under Thickness location, define the thickness location of the entities you want to scale. Use the Edit Elements: Create tool to create new 1D and 2D elements and delete elements. From the Model ribbon, click the Edit Elements > Create tool. Figure 1. Elements are colored according to how well they adhere to the pre-set quality requirements defined in the criteria file. Optional: On the guide bar, click to to define the options used Figure 1. On the right-hand side of the panel, you can review the compound Quality Index, as well as the number of elements and the percentage of elements that failed a quality check. To highlight elements falling at or below a certain quality level, move the display thresholds slider. Lastly, you can access the cleanup tools and save a list of In this step you will create hexa elements in the curved portion of the arm using spin. In the Model Browser, Component folder, right-click on arm_curve and select Make Current from the context menu. Open the Spin panel by clicking Mesh > Create > 3D Elements > Spin from the menu bar. Go to the spin elems subpanel. HyperWorks 13.0 HMD Introduction 7 Proprietary Information of Altair Engineering, Inc. fChapter 1: Basics HyperMesh Desktop Step 1: Pre- Processing Pre-Processing is the act of preparing (meshing) a model for analysis. Complex geometry is broken down into simple shapes (elements) in the act of meshing. Review Element Quality. Use the Element Quality view to review element quality while simultaneously editing your model. The Element Quality view is automatically enabled when certain tools on the Mesh and Elements ribbons are active. To manually enable the Element Quality view, click on the View Controls toolbar and select Element Quality. Element Quality View. The Element Quality view allows you to investigate each specific element criteria, view a breakdown of all failed and worst elements, resolve all criteria violations at one time, and evaluate the over all quality of a mesh.
