How to make connectivity between two parts.If the parts having more elements means how can i select multiple nodes or elements at a time.i am very new to hypermesh plz post some ways.

Thanks

I can't understand your question, please give more informations.

A way to connect to parts with different numbers of nodes are e.g. ...

- go to 2D->ruled

- select 'node list' - 'node list'

- select the option 'e.g. mesh, keep surf', auto reverse on

- select first line of nodes

- select second line of nodes

- create...

dear Mario,

My main task is to create rigid elements between shaft and cylinder.In this case cylinder is mounted over the shaft, both has different materials.

i dont know how to make connectivity between these two components ( Both are 3D elements).

i attempt this by RBE2 and gap elements.While using RBE2 how can i select independent nodes by surface or face. Like dependent nodes (Multiple node option).

Thanks & Regards

Go to

1d panel- spot weld

- select using nodes

-select nodes-nodes

-for independent nodes select nodes on one component ( u can easily do this with clicking nodes and selecting option on face(unselect other than required) or by path)

-for dependent nodes select nodes on other component by same way.

-define tolerance gap

- click create.

Hello,

I think ANALYSIS felt very boring when click nodes one-by-one

Your problem is you need connect 2 parts by many RBE2 elements and you could not select all independent nodes at once, is this right?

If so, exactly you will need a TCL macro, like this example:

*createlistpanel nodes 1 'select node path 1'; # you select 1st node list if independent nodes (on cylinder)

set nodelist1 [hm_getlist nodes 1]

*createlistpanel nodes 2 'select node path 2'; #select 2nd node list of dependent nodes (on shaft)

set nodelist2 [hm_getlist nodes 2]

Rule_Mesh_RBE2 $nodelist1 $nodelist2

Hello

procedure Rule_Mesh_RBE2 could be like this

proc Rule_Mesh_RBE2 {nodelist1 nodelist2} {

set i 0

foreach nodeid1 $nodelist1 {

set nodeid2 [lindex $nodelist2 $i]

if {[hm_entityinfo exist nodes $nodeid1] && [hm_entityinfo exist nodes $nodeid2]} {

*rigid $nodeid1 $nodeid2 123456

}

incr i

}

}

Oh, I ought to post this to HYPERWORKS MACRO box

ANALYSIS, do you know how to run TCL macro?
