Hello fellow forum members,

I hope you're all doing well. I'm currently working on a project involving Fluent Meshing, and I've run into a bit of a challenge. In the Workbench environment, I've noticed that it provides a convenient graph to visualize mesh quality metrics. However, when working directly within Fluent Meshing, I'm finding it a bit tricky to pinpoint the location of bad mesh elements based on certain quality criteria.

Specifically, I'm trying to identify areas in the mesh that fall below a certain quality threshold. In Workbench, I could easily generate a graph that displays the distribution of mesh metrics, making it simpler to locate problematic elements. However, within Fluent Meshing, I've only been able to find the minimum and maximum values for these metrics, without a clear visualization of their spatial distribution.

I was wondering if anyone here could offer some guidance on how to effectively identify the location of poor-quality mesh elements within Fluent Meshing. Are there any hidden tools or techniques that I might be missing? It would be tremendously helpful if there's a way to generate some sort of heatmap or graphical representation of mesh quality within Fluent Meshing.

Since many of you have diverse experiences with meshing and simulation, I believe that your insights could greatly aid my understanding of how to address this challenge. If you have any tips, workarounds, or suggestions for how to achieve this, I would greatly appreciate your input.

Thank you all for your time and consideration. I'm looking forward to your responses and learning from your expertise.

Best regards,

Paul

If you are looking for Surface Mesh quality, you can mark bad quality cells (or other common issues) from the Diagnostics tool.

From the Outline view, expand your meshing object and right click > Diagnostics > Connectivity and Quality.

You will be able to visualize the cells that are problematic for a variety of Issues or Quality metrics. You will also have the ability to make localized repairs for the marked cells.

You can also check for these cells from the pull down menu Display > Grid > Cells tab, check the Quality box and specify the metric you want to observe.
