merge the nodes at the two interfaces about iso2mesh HOT 5 CLOSED

Can function [newnode,newelem]=mergesurf(node,elem,varargin) merge the nodes at the two contacting surface (F1,V1) and mesh(F2,V2,E)? Also, how to distinguish the difference after merging between surface and mesh? I need these for finite element analysis in definition of their properties.

hi @NataCalc, have you tried surfboolean? mergesurf() should also work as it calls surfboolean in the background.

if the two surfaces are "co-planar", i.e., all the nodes are located along the same plane, surfboolean will also have problem merging them.

Hi Fangq,

I have managed to merge two co-planar surfaces. Now, I have to merge Volume (F,E,V) with Surface (F1,V1) where volume and surface share nodes. I have done the joining operation of these two geometries but this is not enough for merging. Do you have this type of function which allows two merge volume and surface meshes?

can you provide a sample script to show me what you want to achieve? without an example or plot, it is hard to comment on workarounds.

are you trying to create multi-layered slabs by merging slabs? if so, that's not the right way to do it. You should use latticegrid() and surf2mesh instead.

Hi Fang,

I have sent to you (your email address) an example.

Thanks
