Problem with non-mappable faces

Hi,

send us your model (partial model) so we can help you faster than writing a guide for you

Hi,

Looks you model built up from thin member, so you should make SHELL (2D) model, share node between members

if you still want to make 3d (but why 3d?), thicken the shell (panel 2d>elem offset>thicken shell), and make RBE2 or RBE3 connect members

Thanks for the advise @tinh

Okey, i followed your way, i dont know i'm doing correctly but my mesh is looking good until i give it a thickness,

elements have 12 T connections warning showed up now  where the components' intersection area.  How am i gonna put distance between them? since i begin to the procedure with solid boolean there is no room for thickness i asume.

Hi,

it is ok to share nodes at the position, so you see 12 t-connections

solver understand it is continuous, it means the two members are fully welded

if you make a distance there, the two members are disconnected and cannot form a structure (unless you will connect them by some else elems like rbe2,rbe3,...)

i ran some tests and my professor told me the shell elements are not proper for our model ( i'm talkn abouth hole bus ) . He wants me to do it as solid body, is there any other      options ?

The only problem i have for now is this, i believe i can progress if i can mesh this part.

Could share your model file?

Here is a part of upper frame of the bus, it's keep going almost same sequence.

The problem is, the components doesn't match perfect as you can see so i found solid boolean is the way to macth them, after doing boolean it creates a surface that i couldn't mesh.

Thanks.

Hi,

I have observed too many CAD modelling error which is not allowing your model to convert in mappable solid.I believe you can correct this easily in CAD software.

Okey, my geometry is not good enough to mesh but when i try to mesh perfect geometry the same issue exist again.

This is the geom. i try to mesh;

is there other problems possible ?

will check this geometry & update you soon.

Here's is my test with full hex meshing.

Hi,

which version you've used, mine is v12 

this is possible with any version of hyperworks.

Then why am i getting ' The file is not backwardly compatible with this version.' message when i try to open @Q.NGUYEN-DAI's upload.

Hi,

.hm files created with HyperMesh 13.0 are not compatible with HyperMesh 12.0.

Yes, I used HM v13.0

Can you make a quick tutorial  the steps you follow making that mesh when you are available @Q.NGUYEN-DAI.

Thanks.
