Curved Joins in GiD

Hi,

First of all I love this program it is very good and I hope to become quite good at it some day!

I am having some difficulties however with how to connect parts that are curved. For example:

I have three items, a metal piece (centre), glue, which is around metal piece that has set(hardened), and a hollow pipe. Basically I want to know how to connect the set glue (modeled in blue) to the curved surface of the hollow pipe. At the moment if I just use straight lines then of course it will leave voids. What are some recommendations people here have?

Attached is an example of what I am talking about and the hollow pipe in GiD.

Thank you

DN

I recommend you to discard the very small region between the straight line and the arc. It could be impossible to fit mesh elements in a too thin volume. Off course it depends on the kind of simulation to do.
For example use as side for the rectangle the arc instead the straight segment.
I attach a GiD model build from scratch based on your picture.

You must simply unzip the file (that contain a .gid folder)
and then start GiD and select this folder in preprocess with
Files->Open
