Ansys Mesh Meshing

Click For Summary

SUMMARY

This discussion focuses on meshing techniques in ANSYS for a longitudinal weld analysis using the effective notch method. The user aims to create a precise mesh by generating Keypoints for node placement, specifically utilizing Mesh200 elements for initial meshing and converting to Solid186 elements for 3D modeling with Vext. The primary challenge faced is the inability to generate a mesh that aligns the nodes with the defined Keypoints.

PREREQUISITES

Understanding of ANSYS meshing techniques
Familiarity with Mesh200 and Solid186 element types

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.
