Hi Everyone,

I am struggling getting a decent mesh for my simulations. On my geometry having a mesh without inflation layer gives an orthogonal quality of 0.05, providing decent results on the pressure output and the end of the computations. However, reading on other posts on inflation layer, working without it is like rolling the dice.

With an inflation layer instead, the orthogonal quality drops to 5x10^-7 and I have divergence.

My question is: what's the treshold to say wheteher or not using inflation layer? Do you have any suggestion?

My model is a 3D wastewater pump with 0.3mm impeller-casing gap.

Thanks.
