Hi everyone,

I'm working on running a few Fluent analyses on journal-bearing fluids. I'm currently facing low-quality meshes on a spiral-grooved model which looks like this

I've tried various meshes: default, patch confirming, multizone etc, but the best mesh I got still had
Skewness (max): 0.99994
Orthogonal Quality (min): 5.5334e-005

Due to this poor meshing, my calculation is getting failed with:

Error at host: floating point exception

Error at Node 0: floating point exception

Error at Node 2: floating point exception

Error at Node 3: floating point exception

Error at Node 1: floating point exception

Error: floating point exception
Error Object: #f

I read somewhere that creating a structured hexagonal mesh would increase the element quality, but all the examples I'm seeing for that have symmetrical bodies wrt the front plane.

Any leads on how to do it for the spiral grooved body? Or what meshes should I do on what parts? Or any video or thread which has a similar requirement. The body is sweepable.

I'm attaching the snips of the current Skewness & Orthogonal Quality

Thanks!
