Modeling of 2 pipes for snappyhexmesh

[Mr. Pieter Van Driessche 0]

I got a newby question for Caeses. I'm trying to model an elbow with a second pipe connected to use for CFD simulation (meshing with snappyhexmesh).

I have attached my model.

When I try to mesh this, the result is only the big elbow. the small pipe is not meshed.

I think I'm missing something obvious, but I can't figure it out;

 

Thanks for the help!

Hi Pieter,

 

I recommend to check the brep tutorial . There is also a sample file included which looks similar to your example: . Your model is not a clean solid, that's probably the reason why you cannot mesh it. You need to create a union (Boolean operation).

 

I hope this helps,

Joerg

Thanks for the reply. I'm not sure if I understand your comment as I have a boolean operation (union) in my Brep02 that is merging the elbow with the small pipe? Do I need to do this different?

Hi Pieter,

 

Like I said, just check the very basic sample project :-) The result in there is different, and I think this is what you need. Maybe you have to close your small pipe before applying the Boolean operation. Your project is also quite slow, compared to the sample file so it seems that there is something not ideal.

Closing the holes in the small pipe worked!

 

Thanks
