On the other hand, the FE model is comprised exclusively of nodes and elements. It is comprised exclusively of volumes, areas, lines, and keypoints (a.k.a.: vertices). #IMPORTING SOLIDWORKS INTO ANSYS SPACECLAIM SOFTWARE#The former is the typical solid CAD model that most would be familiar with from a drafting software package, such as SolidWorks or Inventor. Behind the scenes, the software recognizes these two aspects separately. I would like to first briefly explain two basic aspects when discussing modeling in Ansys: solid model and finite element (FE) model. Differing Modeling Types: Solid Model and Finite Element (FE) Model #IMPORTING SOLIDWORKS INTO ANSYS SPACECLAIM LICENSE#This article presents a workaround available to force connectivity between CAD bodies when using contact is not an option and when a DM or SCDM license is unavailable. Many other CAD packages create “assemblies, parts, or groupings” of some type, but none are recognized as MBPs in Mechanical, except when done so by DM or SCDM. Forcing Connectivity between CAD Bodies when Contact is Unavailable ![]() In this latter case of creating MBPs, you’re stuck if you don’t have a license for DesignModeler (DM) or SpaceClaim Direct Modeler (SCDM), both being the front-end CAD packages available in the Ansys product lineup, and both having the ability to create bona fide MBPs that Mechanical recognizes. What if i don’t have a license for DesignModeler or SpaceClaim? This is again very similar to a merging action where single nodes take care of the connectivity of adjacent elements from adjacent bodies. Another common alternative that’s been around longer is to simply group CAD bodies into a “multibody part” (MBP), which then forces Mechanical to recognize their connectivity and interaction with each other. Users might take advantage of the newer Node Merge option that was released in v16.0 of Workbench (WB) Mechanical. There are several alternative ways to make adjacent bodies interact without using contact. Sometimes, this may be no issue if the region is not of interest, but sometimes it can be an issue. ![]() Specifically I’m referring to the use of bonded contact in this article, although other contact behavior types run the same risk. This resource guide will provide all you need to know about CAD geometry in Mechanical WB. It’s a nature of the beast and a result of the numerical activity taking place as the contact and target elements interact with each other. Seasoned, veteran users know that you run a small risk of stress blips very near a region where contact is defined.
