Hi, I´m brand new in CFD and I´m trying to simulate a pump impeller. I did all de tutorials I found and so far everithing was ok.

Then I modeled my oun impeller (the impeller exist and works fine, I work for a pump factory and this is the impeller of one of our pumps) but when I´m trying to simulate I found that the flowlines crosses the stationary walls.

What am I doing wrong ???

I attached a picture of the disaster

Impeller diameter: 178mm
Q = 125 GPM = 0.0079 m3/s
H = 60 mca
n = 3550 rpm = 371.75 rad/seg
static pressure at outlet lid = 637414 Pa
Internal analisys
Global rotating
Resolution Level= 4
Minimum gap size= 0.04m
Minimum wall thickness= 0.01m
