Create Mesh on CAD DATA

Recommended Posts

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) ?Pic-1.thumb.png.43498e26ec94f023125eadc934bd61a7.png

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.

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 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
