Associate 2D mesh with surface

To my knowledge Automesh panel creates mesh on selected surface & ensures connectivity of mesh with surface.Meshing on planar area will not have any issue of node to surface connectivity.

Hi Rahul,

my question is not on automesh panel. I was referring to an already meshed surface using the automesh option, where the mesh has to be translated (for some reason) say on the y axis. If you translate the associated surface on the same axis and the same distance the two entities (mesh, surface) are not related to each other anymore (as expected). How do you re-associate them quickly and accurately?

I think this option is meant for local region where you have slight movement of nodes from surface.If you want movement or changes to me made on entire geometry then try Hypermesh morphing techniques.

Understanding you because I faced it many times.

I have script to do that.

In a simple case, you can F11 toggle all green lines, your cad will become 1 surf and you can associate nodes in one click

Yeap, I am aware of the morphing techniques and this can solve the problem, but I was looking for something outside the morphing options.

@ tinh:  Good suggestion there mate! Thank you. 

@tinh can you share your script? It is currently very tedious to re-associate nodes to geometry. A script/function that allows selection of multiple surfaces/lines at once in the node edit panel would solve the issue.

You can toggle all lines and associate all nodes in one click

another way, make a solid from the surfs so you can associate nodes to the solid, no need to select surf by surf.

my script is for internal using and not suitable with other works, it links to many private functions and procs

I think one can associate nodes (& thus mesh/elements) to existing surfaces/solids. IIRC, in Nodes Edit Panel, there is an associate command/radio button. I won't be able to post the screen shot of it until tomorrow around same time.
