retrieve surfaces

Altair Forum User

Hello 

 

so I am creating a program in which I trim a surface with lines 

 

and in later part I retrieve the trimed surfaces automatically (using *createmark surfaces 1 -1 -2)

 

*createmarkpanel surfaces 1 'select surfaces'

*createmarkpanel lines 1 'select lines'

*createvector 1 0 0 1 

if { [ catch {*surfacemarksplitwithlines 1 1 1 9 0 } ] } {
# Handle error
}

*createmark surfaces 1 -1 -2

*interactiveremeshsurf 1 4 1 1 2 1 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1
 
*automesh 0 5 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1 

*set_meshedgeparams 1 19 1 0 0 0 4 0 0
 
*automesh 0 5 1 

*storemeshtodatabase 1 

*ameshclearsurface  
 

 

have alook at image attached 

 

so i want meshing inside the inner circle and in between the two circles

 

and I also would like to know  how  *createmark surfaces 1 -1 -2 works??

<?xml version="1.0" encoding="UTF-8"?>

I am able to wish only part in between two circles with above program

 

so how can I assign the inner most surface directly I tried all -1,-2,-3 its not working

 

 

<?xml version="1.0" encoding="UTF-8"?>

 

 

and I also want that newly created inner most mesh should be organized in a new component 'TAP WELD'

Hello

 

so I have made some changes and now I am able to mesh both the parts properly

 

*createmarkpanel surfaces 1 'select surfaces'

*createmarkpanel lines 1 'select lines'

*createvector 1 0 0 1 

if { [ catch {*surfacemarksplitwithlines 1 1 1 9 0 } ] } {
# Handle error
}

*createmark surfaces 1 4

*interactiveremeshsurf 1 5 2 2 2 1 1

*set_meshfaceparams 0 6 2 0 0 1 0.5 1 1

*automesh 0 6 2

*storemeshtodatabase 1

*ameshclearsurface
 

*createmark surfaces 1 -2

*interactiveremeshsurf 1 4 1 1 2 1 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1
 
*automesh 0 5 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1 

*set_meshedgeparams 1 19 1 0 0 0 4 0 0
 
*automesh 0 5 1 

*storemeshtodatabase 1 

*ameshclearsurface  
 

 

still working on organizing the element to a perticular component

 

let me know if anything is wrong in above programs

 

Thank you

so I am able to organize the elements into components name which is given in the script

 

 

*createmarkpanel surfaces 1 'select surfaces'

*createmarkpanel lines 1 'select lines'

*createvector 1 0 0 1 

if { [ catch {*surfacemarksplitwithlines 1 1 1 9 0 } ] } {
# Handle error
}

*createmark surfaces 1 4

*interactiveremeshsurf 1 5 2 2 2 1 1

*set_meshfaceparams 0 6 2 0 0 1 0.5 1 1

*automesh 0 6 2

*storemeshtodatabase component1

*ameshclearsurface
 

*createmark surfaces 1 -2

*interactiveremeshsurf 1 4 1 1 2 1 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1
 
*automesh 0 5 1 

*set_meshfaceparams 0 5 1 0 0 1 0.5 1 1 

*set_meshedgeparams 1 19 1 0 0 0 4 0 0

now I want to create those lines created around the hole (washer automatically) probably twice the radious of the hole

<?xml version="1.0" encoding="UTF-8"?>

Altair Forum User

hello

 

there is a problem in my file I am not able to understand please see if you can help

 

I have a surface having hole and washer (grey) and another overlapping surface on it (L section blue) no hole and all

 

so I have written program which will trim the l section blue surface with the hole and washer line on the gray surface

 

and then mesh the inner most and in between part with given parameter 

 

but its not meshing how I want (or by defined parameter) 

 

and also its meshing all the outer part which I dont want

 

''3.png'' is how I want but I am gettinh as shown in ''dont want like this''

<?xml version="1.0" encoding="UTF-8"?>

<?xml version="1.0" encoding="UTF-8"?>

tinh

where is 3.png?

maybe just wrong surf id

when you trim a surf into several, their ids are mess up. try regconizing them by area or edges

Altair Forum User

So how can I do that I want to do it without user interface 

 

 

When I select -1 it actually selecting two serfaces 

Altair Forum User

hello tinh

 

above program is right my only mistake was I was trying it on already meshed part so not able to get desired result

 

Thank you
