Create Mesh on CAD DATA
Hi my friends.
I have some CAD Data( 3D Drawing, face of car's , With Thickness=0.0).
some file's have overlap and Some File's have offset (thickness).
when I define property , the mesh is known with Mid Surface, I think that isn't good idea for create mesh
in attachment , is described at Fig.1 and fig.2
in Fig.1 two surface haven;t offset , but in Fig.2 two surface have offset (3mm)
My problem:
I think ,at fig.1,the first create mesh for every surface then define Property ( Thick part.A =2mm , Part.B=0.7mm)
But at Fig.2 , i don't know , can i create mesh according to the last method ( same as Fig.1) ?<?xml version="1.0" encoding="UTF-8"?>

Hi my freind
Can I Offset the Source Surface for both parts with (Tickness/2) and then Create 2D mesh ? or i should be create mid-surface for both parts and mesh it separately
Hi Korosh
Can u share the model file, i will have a try.
You can use the secure transfer link https://ftin.india.altair.com:8443/filedrop/~Ma3TaE
Hi My dear
I sent Two Cad file ( Little Area of Rear Frame )
Each part have 2 mm Thickness and both direction are inwards.
So i should be ,create 1 mm Offset for each parts and then i will create mesh.
for example , if after create mesh and Crush Analysing , the result not acceptable , and i want to change thickness to new value 2.5 mm ,then Reanalyse Crush test.
In this level , do i have change Mesh of tow parts with new offset (1.25 mm) and change all Spot weld , contact ,... ?
(Consider that for Real side crush i have 52 different parts of car)
Best regards
Hi Korosh
You can Offset the 2 surface (Part A & B ) using geometry > surface edit > offset
Then after offsetting you can create mid-surface for both parts and mesh it separately
Now you can assign separate thickness for both the parts.
