Hi everyone,

I am not sure how to model this so I am asking the question. The geometry is as follows.

I have a DN1500 pipe running horizontal. From two places a 45 deg DN900 branch is connected to the main pipe. I am not sure what is the correct way of modelling this. there are two options, both discussed below.

1. Model DN1500. Model DN900 as a reinforced fabricated tee connection right at the junction of DN1500 and DN900, OR
2. Model DN1500. Model a rigid for the branch till it comes out of the DN1500 pipe. Then model DN900 branch.

My problem is, if I model as option 2, where should I place tee connection? At the intersection of DN1500 and rigid or between rigid and DN900?

Thanks
