Meshing from given nodes and geometry

Hi Mehlil Ahmed

Can you please explain more with some pictures.

As per my understanding if you already have a surface created, then you can use that surface for creating new mesh. Then you can remesh using Automesh panel.

In Automesh panel you have the option For Anchor nodes. So you can select those fixed nodes and mesh the remaining surface so that the anchored nodes stay fixed and do not move.

Hello

I imported 8832 nodes in Hypermesh and created a surrounding geometry or surface i should say. Now can anyone help me about how to mesh this? While meshing with new geometry i want hypermesh to use the existing nodes as they are and create additional nodes to mesh the new geometry. How this will be possible to mesh a new geometry with imported nodes in that geometry? Can anyone please help me regarding this?

 

Regards

Hello @Pranav Hari

I have these nodes  imported and saved from previous file. Now i have created another geometry. Now i want to import these nodes into this geometry and mesh it. While meshing it should preserve these given nodes and creating new nodes.  I want to use quadratic tetrahedral elements. Can you please give me an idea how to do the meshing preserving these node datas? I have tried your method but after meshing it ones it becomes difficult to choose the nodes to be anchored as you can see the combined geometry and node image that after importing the nodes they are inside the geometry. I am very much new in Hypermesh . So i am not understanding correctly how to do it properly .

In 2D mesh, you can do it. But in 3D mesh I don't know how to do it.

Why you need this kind of meshing? Maybe you have another way to do?

Hello @Q.Nguyen-Dai

Thank you so much for your reply. I am doing this for my project. I have some values for the preserved nodes. By meshing this geometry which will include these nodes and also create additional nodes ,i am going to use this new mesh for a FEM simulation. As i am pretty new in Hypermesh i do not know how to do this 3D mesh. If you can suggest a way that would be very helpful.

The imported nodes present a 3D mesh?

Yes i imported 7026 nodes from a 3D mesh, and the rest of the nodes i have included as i have datas for them which i want to analyze.

Could you share your model with imported nodes + new geometry ?

This is my Hyperworks file including the nodes and the geometry.

If all imported nodes are found inside of new geometry, it's possible. In this cas, just keep external 2D mesh of old solid mesh and add new layer mesh.

Thank you so much for your help! Finally i was able to do the meshing just how i needed.
