Automate node creation

Altair Forum User

Hi,

I need to create nodes for elements of user specified sizes. For eg, If the user specifies size 6 for the element, the nodes should be created at (0,0), (0,6), (6,0), (6,6). If the user specifies size 8 for the element, the nodes should be created at (0,0), (0,8), (8,0), (8,8). This is to be repeated to generate a geometry 830 mm*450 mm . therefore, if the element is of size 8, 830/8 elements must be created along the length and 450/8 elements along the width with their corresponding nodes. Please tell me how to automate this? Also, I need flexibility to change 830*450 mm dimensions to user specified dimensions (say 500*250 or 1000*600 etc etc). How do I incorporate this??

 

thanks,

Kushal.

Hi kushal

 

it is not possible to create element of same size within that dimensions i.e 830*450 until element size completely divide dimension 830 & 450 

user specified size say 8 , does not divide 830 completely so every element size can't be 8..

 

#####Script 

 

set length [hm_getint Length 'Enter the length']
set width [hm_getint Width 'Enter the Width']
set elemSize [hm_getint size 'Enter the element size']

set length_count 0
set width_count 0

while {$length_count < $length} {
    while {$width_count < $width} {
        *createnode $length_count $width_count 0 0
        incr width_count $elemSize
        if {$width_count >= $width} {
            *createnode $length_count $width 0 0
        }
    }
    set width_count 0
    incr length_count $elemSize
    if {$length_count >= $length} {
            while {$width_count < $width} {
                *createnode $length $width_count 0 0
                incr width_count $elemSize
                if {$width_count >= $width} {
                    *createnode $length $width 0 0
                }
            }
        }

}

Hi,

 

You can create one big element with that dimension for example 830x450mm, do a remesh on that element with 8mm mesh size/all quads then get all the nodes.
