How to create Node along a Line

Altair Forum User

Is there a way in Hypermesh to create a Node along a Smooth Line (Spline) specifying the length ? Please Help thanks.

Hello,

 

Try menu 'Geometry->Create->Nodes->Extract on Line' for uniform distribution of xx nodes on line.

Try menu 'Geometry->Create->Nodes->Extract parametric' to generate a node with parametric coordinates.

Try different numbers of nodes (e.g. two nodes generate a node on U lower and U Upper, e.g. 0.25 - 0.75)

Hi Mario,

 

Thank you for your reply to my problem. I am modeling the outside shell of a Ship. As you know the outside shell of a ship have curvatures. I have Lines Drawing of the shape of the Hull. Now my problem is I need to create a Node/Point along the curve specifying the length along that curve. In short say if I have a Spline Line ( not Arc Curve ) and I need to create a node 800mm from one of the end of the Curve, if you flatten/straighten the Spline Line it will measure 800mm. Can it be done ? Thanks in advance.

Hi Erwin,

 

Yes, you can do it, but you have to calculate a little bit...

 

1. Measure the length of the curve, 'Geometry->Check->Lines->Length (e.g. 5400)

2. Calculate the parametric length of your section (e.g. 800->0.148148)

3. Use 'Geometry->Create->Nodes->Extract parametric'

4. lower bound = parametric value, upper bound = 1, number of nodes = 2, arc length

 

You can cut your line at the node and measure the length again for testing...

Hi sir,

In hypermesh how to use arc node and vector tool

     how to select vector.... pls quick reply.....

Hello,

 

You need to create a vector for that.

You can do this by 1D>>vectors

 

Please find more information on how to use the different tools on Help Section

thanks sanjay

 But what are the vector elements....

I cant select any node, line, point.... so which is vector...

You have to create vector elements. 

Vector elements are not nodes, line, point etc.  

You have to create a vector element from 1D>>Vectors.
