Is there a way to split lots of 1-D elements all at once

Altair Forum User

Hello everyone,

 

I am currently working on a lattice structure made of beam elements and I would like to split all those elements into two, in order to increase the mesh's density. So far I have found how to split 1-D elements by drawing a line... but considering there are close to 26 000 elements, this method is definitely not ideal here !

 

So my question is: is there an easy way to select all the 1-D elements and split them into two 'in one click' ?

 

Thank you in advance for your time.

Hi

a simple Tcl script may help you:

 *createmarkpanel elems 1 'Select 1d (bar2) elements:' *createmark elems 2 'by config' bar2 *markintersection elems 1 elems 2 set ENum  [hm_marklength elems 1] if {$ENum} {      eval *createarray $ENum [lrepeat $ENum 2]      *elementmarksplitwith1D 1 1 $ENum } *clearmark elems 1; *clearmark elems 2

Hello,

 

Thank you for your answer; I will look into it (might not be instantaneous since I started using HyperWorks only a month ago)

Hi Matthieu,

 

Here is a macro for splitting 1D elements in 2 in one shot . I hope it will solve your problem and time

 

*createmarkpanel elements 1 'select beams to split'
#set elem_list [hm_getmark elements 1]
set num [hm_marklength elements 1]

hm_commandfilestate 0
hm_blockerrormessages 1
hm_blockmessages 1
*entityhighlighting 0
hwbrowsermanager view flush false

eval *createarray $num [string repeat '2 ' $num]
*elementmarksplitwith1D 1 1 $num

*entityhighlighting 1
hm_commandfilestate 1
hm_blockerrormessages 0
hm_blockmessages 0
hwbrowsermanager view flush true

Thank you for your help ! I will try the macro as soon as I get the time, as I am quite busy on other projects at the same time

Hello All,

Can anyone please explain me which parameters are considered in *elementmarksplitwith1D command?

Before this command we are creating one array, which values we can use in this array?

Thanks & Regards,

if i'm not mistaken this array of repeated '2' means that for each element 1d, you will split them into '2'.
