Ansys Mesh Meshing

Click For Summary

The discussion focuses on the challenges of meshing a longitudinal weld using the effective notch method in ANSYS. The user aims to create a fine and specific mesh by generating Keypoints for node placement. They intend to use Mesh200 elements for a 3D model with Vext, transitioning to Solid186 elements. However, they are struggling to achieve a mesh that aligns the nodes with the defined Keypoints. This issue highlights the complexities of precise meshing in finite element analysis.

TL;DR: I need to analyze a welded joint and the method requires a very specific type of mesh. I tried to base it on Keypoints but can't manage it.

I'm analyzing a longitudinal weld using the effective notch method to modell it. This means my mesh must be fine and more importantly very specific. To do this, I generated Keypoints where I want the nodes of the finite element mesh to be and this where I was stumped.

I want to mesh it using Mesh200 elements and the make it 3D with Vext and finally turn it into Solid186 elements. My problem is that I can't seem to create a mesh where the defined Keypoint give me the nodes in the mesh.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
