3D meshing of a screw
Altair EmployeeHello,
I am trying to 3D mesh this model with solid mapping.
I have already tried 'toggle edges' and 'trim with surf'. I have also tried to divide the circular plate (top plate) into small pieces by connecting the nodes, however, I was not able to split any surfaces.
I am not exactly sure which edges I should toggle and how I should get rid of the narrow surfaces between the rectangular (side) surfaces, to make the model mappable?
Thank you,
Muge Candogan

you want only hex element or tetra is also fine?If possible please share hm file for same.

Hello Rahul,
Thank you very much for your quick response.
I am trying to create hex elements with solid mapping. Since the geometry is complex, would there be an easier way to mesh that you recommend?
I am also sharing the hm. file to your dropbox.
Thank you very much,

thanks for sharing files.Hex mesh with solidmap is all about how you are splitting model to get mappable volume.to me also it seems complex.PFA screenshot for same.Will check & let you know my finding on this model.

Hi,
could you attach the file in a post? we can give a try.

Thank you so much for your responses. I am attaching the file.
Is there an easier way that you would recommend, such as tetra mesh? If so how should I proceed with it?
Thank you,

hi, tetra is always easier than hexa, if you don't have any specific reason, use tetra model

I also tried volume tetra but it did not work either, could it be because I need to edit the geometry?
Thanks,

Yeah, Tetra mesh is NOT BAD when you known how to use it !!!
If you want always HEXA meshing in this case, I would like to say 'Good luck!'

I am trying tetra meshing, however, only the top part can be meshed, I can't get any results for the rest of the geometry.

You mesh size is TOO BIG comparing to your geometry. Try with smaller value.

That solved the problem! Thank you so much!!

Even with Tetra meshing, you can not got the best mesh (good quality with reasonable CPU) with ONE CLICK
A good mesh needs a hard work.
