Imprint Operation Failure

In this project the error is occurring saying that partial contacts detected,so Imprint your geometry.But this operation is failing several times after 10% of run.So , I am expecting a solution on this.
This is the link of my project : https://www.simscale.com/workbench/?pid=2163254675728941609&mi=operation%3A41%2Cgeometry%3A32&mt=GEOMETRY_OPERATION

CFD Squad, could you have a quick look at this user’s issue? Jumping back in later on!

Best,

Jousef
