Is that a fine enough mesh at the joint?

I think those are just lines to make the object look solid.

It should look like this when done:

That crotch plate is essential for preventing the pipe from tearing apart under pressure.

Huh. Interesting. I guess I do n’t know much about pipes (or engineering for that matter). How does the crotch plate reduce stress? is it internal pressure that would cause it to burst, or is some outside force crushing in?

FEAs are fun. What kind of forces are you testing? Pressure?

In this situation the pipe is being pushed down a hill due to a land slide. The actual working pressure is about 100 psi, which is really low for this material which will be 1" thick welded steel pipe.

When you cut a huge hole in the side of the pipe it looses it’s hoop strength so you need to reinforce the outlet with the crotch plate. The crotch plate keeps the pipe from collapsing due to static loading from soil cover or live load due to cars and trucks.
