Meshing

Hi Novak,

may i know the purpose of 3D mesh?

Thank you

The container is a 3D object, so I need it to be a solid. I am trying to mesh it with tetramesh, but it doesn't seem to mesh all the solids.

Thanks

The model is not enclosed. Hence, you are not able to perform 3D mesh. I suggest you to go with 2D mesh only, its better.

Thank you.

But I can't. The model is solid, it needs to be 3D meshed. Could you please tell me how to enclose the volume.

Thanks

Delete your 2d mesh. And try volume tetra mesh.

Thank you

well I m suppose to first to the 2D meshing and then use that mesh to create a 3D. I am not suppose to use volume tetra directly. Also, the meshing with volume tetra won't be as good as tetramesh.

first please check your geometry and make sure there are no free edges and no missing surfaces (fill the missing gaps).

Thank you.

I have sent you a file by email. I did remeshing with size and bias panel. I checked for free edges and there are none. However, when I try to do tetramesh, 3D meshing is not performed.

Please have a look

Thanks

Now tetramesh seems to work actually, but could you please check how can I make it look bit better.

Thanks

I think your mesh looks perfect. You can go ahead with this.

Thank you

Okay! Thanks for your help

I have another very similar model in which as I try to tetramesh, there are some error elements. When I try to toggle them, lots of free edges come out. Could you please have a look at the model and tell me the solution. Really getting stuck at it.

Thanks

Hi,

I don't see any point for 3D mesh for this component. This is a plastic component. You need to extract mid surface, clean-up the geometry and mesh with shell elements.

Thank you

Hi

Well I see your point but the task is to do the 3D mesh. I don't really have the option which you are talking about. Could you please tell me how to perform 3D mesh

Thanks

Please reply. It is bit urgent

Thanks

Hi Novak

The component thickness is very less, ribs thickness is around 1.5mm. So, it is not possible to allocate 3D elements. You need go with 2D mesh only.

Thank You

@Novak

There are self-intersection points which makes meshing with 3D difficult. Refine the geometry and use a very small element size or extract the mid-surface and 2D mesh it... Up to you... 

Hi @Novak

As said it is always better to extract mid surface and use 2D elements for modeling for such components.  If at all you need to 3D mesh it make-sure you have a completely closed volume of mesh.

One other way is 2D mesh the component with Shrink wrap which makes the component closed for tetra meshing. But this may not capture the component properly. 

Apart from that, I see a lot of intersections in geometry which may not help with 3D meshing. 

Is there no quick way to get rid of those interesections?

For CAD there is no option to get rid of intersections in HM.

Try with a professional CAD tool.
