Unable to align elements, surface trim and seperation

Altair Forum User

Hi, 

 

In the first picture. where the 4 circles are, i am trying to line up the elements. The geometry was cut up (In CAD) into sections to help me with solid mapping but for some reason not able to section further. I tried to equivalence but not sure how to get it just right. 

 

 

 

In the second picture, i want to add a static pressure on the inside walls, however due to my sectioning, when i select elements by face, all elements in plane are selected. how can i define the inner surface as the face.

Second problem will get resolved once you correct the first problem of connectivity.You should have used solid edit option to trim solid in Hypermesh. If possible share hm file with geometry.
