Geometry errors for analysis model

does anybody have difficulty to build analysis model?

I've tried to make simulation with different fans blades, however, it happened very often to me that even simple shape geometries have edges/faces interferences.

When I tried to adjust maximum length or for faceter parameters, it gets much slower and still couldn not build the analysis model.

Does someone have good tips for building model?

Hello, mr. Hsun, if it is not bothering you, I would like to ask mr. Chuel about something too in edge/faceting option if you please.

Mr. Chuel, how can i determine the "maximum edge length" of a cad part? Is this something done automatically? Or are there basis where i choose such length? Also, regarding the "Lower limit of angular precision", do i need to decrease this value from 10 to 0.5 when i deal with edges that have curvature? since i don't know how to make the best use of it.

Thanks in advance.
