Hello Everyone

 

I have a buit weird geometry which I need to mesh. For that I used normal 'size and bias' method and then tried to clean up till quality index of 30. I have couple of questions.

1.) Could you please check my 2D mesh and tell me if it looks okay or not.

2.) Secondly, how do I make a 3D mesh now out of this surfaces.

 

Thanks in advance

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

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

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.

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

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

 

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

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.
