How to have mesh nodes at certain locations?

Hi everyone,

 

I'm a beginner in Hypermesh, so this may be a very basic question, but I just don't find the answer on the internet: how to generate a mesh such that you have the mesh nodes at some previously given locations? 

 

To make it concrete, suppose I have a cylinder with two points on it (as .igs file). It looks like this after imported into Hypermesh:

And then I tried this way:

1). First, create nodes at the locations of the points:

 

2). Go to 2D Automesh:

And the result is that the nodes I created didn't become part of the mesh nodes.

Does anyone know how to solve this problem?

 

In my further work, some surfaces (but not all) should have a finer mesh. The way I do this is to choose these surfaces and a smaller element size, and click on "mesh". 

Is it still possible to keep "my nodes" as the mesh nodes during this process?

 

I hope you could help me with this problem. Thanks a lot!

hi,

if you want HM to have a node into a specific point of your geometry, you need to add a geometry point into your surface.

This can be acomplished by projecting these nodes into your surface, using geom>>point edit.

Once you have the point into your surface (it is shown as a small dot into your surf, just like some other construction points into your surface edges), then, HM will need to put a node there.
