Creating a Smooth Transition Between Two Different J-Weld Profiles
Hi, I'm using Altair Inspire to create a J-weld geometry on a pipe. The weld cross-sections are different, as shown in the image below: the profile on the left differs from the profile on the right. My goal is to create a weld solid that follows the pipe circumference while smoothly transitioning from the left profile to…

How to choose bearing force direction.
Hello, I'm trying to add a bearing force on a cilyndrical face, but it automatically selects one of the two radial directions, and it is impossible to change it. I've tried making a new system for the cylinder, but the problem persists, it always selects the same direction. As shown in the image, the bearing force is…

Replace updated CAD (only modified)
Hello, I am trying to understand Hypermeshes capability to work with CAD programs. SInce there can be some non trivial geometry chages in an FEA process, sometimes updating the original CAD is easier than hacking some surfaces in Hypermesh. Since there are patchmesing and representation capabilitys to auto regenreate…

Question about a post regarding MotionView coupling with EDEM and Inspire in the community.
This post explains using Inspire to parameterize the geometry, then importing the parameterized model into EDEM, and finally coupling it with HyperStudy. I understand all the steps up to this point. However, I’m confused about the part where the parameterized geometry is imported into EDEM and then coupled with MotionView.…
