Hello, I've been trying to improve the quality of mesh for a vehicle frame. I built the FE model and found quiet a lot of quality errors most of which were warpage and Jacobian. I understand the importance of the two criteria. But I'm just not able to bring them down to 0. I've tried reducing the element size of the whole components. I have two questions in the process. 1. Can I keep the element size of the curved surfaces very low (around 0.1mm) while keeping the rest of the components (without any quality problem) somewhere around 2mm ? 2. What can be done to keep the model out of quality errors on the whole ? Because I have around 86 components to deal which will become tedious. Thanks in advance
I have been asked in an interview- " Does only quad element warp ? " I said "yes". "Then what about second order tria elements ? do they warp ? " I was confused because there is possibilty of warpage due shifting of middle node in second order elements. I guess It will get warp. Will you please tell correct answer for above questions with correct explaination. Thanks and Regards, Pratik
