Generate surf mesh from XYZ data also matching the nids

ashfaq267

Hello,

I have a set of data which is in below format

nid x y z]

.

.

 

but it does not have any details about the elements. coordinates are for a cylinder and elements are probably quad.

Is it possible to generate surf mesh using this xyz data in HM while also keeping the same nids?

Please advice!

Hi Ashfaq,

 

In general, you have to define connectivity table on your own.

 

For exemple, I have a linear Hex mesh of 2D structure 2x4 mm, the nodes and elements will be like : 

 

*NODE (the structure is nbre of node, xCoord, Coord)

1, 0, 0

2, 0, 2

3, 2, 0

4, 2, 2

5, 4, 0

6, 4, 2

*element (the structure is nbr of element, nod1, node2, node3, node4)

1, 1, 3, 4, 2

2, 2, 5, 6, 4

It's an example, but it's the same idea in OptiStruct or any other FEM solver ...
