Geometry visualization resolution

Please login with a confirmed email address before reporting spam

I'm trying to model a geolocated problem. As such, one of the elements of my geometry is a 1m diameter tube, which is located around y coordinate 4E6. This contrast in coordinate and geometry size causes my cilinders to look jagged and artifacty, even when selecting a "Fine" resolution for visualization. My mesh also appears to have artifacts around these features, but the mesh quality shows that it really is just a visual effect.

Any way to configure COMSOL's renderer to an even finer resolution?

I didn't find a way to improve the resolution of the graphical interface, but I found out some things. I'll leave them here in case someone stumbles upon this post when working with georeferenced data in COMSOL.

  1. The artifcacts are only a visualization problem. Your problem will yield the same results as if the visualization was working fine.
  2. Try working in local coordinates. Take your minimum x and y coordinates. Use the 'move' operation to displace you whole geometry to local coordinates, by substracting your x and y on that move operation (z too if applicable). Your geometry will have the correct appearance now.
  3. If you later want to georeference your results, you just need to add the x and y you previously substracted, and there you go, you can get both COMSOL's visualizations working right and your geolocated data.
