How to get midpointx midpointy value for a crosssection

Altair Forum User

Hi , 

 

i need to get cross section values from the HM.

 

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

For your reference i attached the image,

 

from this image we can understand there details of the selected crosssection.

 

 

 

Used code to get the details 

 

Set SecID '320014'

set SectNam [hm_getcollectorname crosssections $SectID]  ##This giving the  name of the Cross Section ##

But while trying to get the midpointx ,midpointy ,midpointz its always giving 0

 

            set MidX [hm_getentityvalue crosssections $SectID midpointx 0]
            set MidY [hm_getentityvalue crosssections $SectID midpointy 0]
            set MidZ [hm_getentityvalue crosssections $SectID midpointz 0]
            set MidNode [hm_getentityvalue crosssections $SectID basenode.id 0]
            set NormalX [hm_getentityvalue crosssections $SectID normalx 0]
            set NormalY [hm_getentityvalue crosssections $SectID normaly 0]
            set NormalZ [hm_getentityvalue crosssections $SectID normalz 0]

 

for this i getting zero for all.

 

Kindly help me to solve this issue 

 

Thanks in Advance

Hi,

crosssections do not have data names as midpointx, midpointy, midpointz

for normal, you have to input data names 'Normal_x' 'Normal_y' 'Normal_z'

refer to help document about data names of crosssections

Hi Tinh,

 

i need to change the nodes of the cross section i used this code to change the nodes but its not changing. 

 

##############################################################################

    #After Importing the Sections 
    
    #getting the sections in a list 
    
    *createmark crosssections 1 'all'
    set sec_ID_List [hm_getmark crosssections 1]
    
    #for createing the cross section need to select node first 
    
    foreach secID $sec_ID_List { 
    
        #giving user to select the N1
        
        *createmarkpanel nodes 1 'Select the Orgin Node'
        set Or_N1 [hm_getmark nodes 1]
        
        *createmarkpanel nodes 1 'Select the Axis Node N2'
        set Ax_N2 [hm_getmark nodes 1]
        
        *createmarkpanel nodes 1 'Select the Axis Node N3'
        set Ax_N3 [hm_getmark nodes 1]
        
        #setting the selected nodes 
        puts 'secID = $secID'
        puts 'Or_N1=$Or_N1'
        puts 'Ax_N2 = $Ax_N2'
        puts 'Ax_N3 = $Ax_N3'
        
        *setvalue crosssections id=$secID Axis_Origin_Node_N1= { nodes $Or_N1 }
        
        *setvalue crosssections id=$secID Axis_Node_N2= { nodes $Ax_N2 }
        
        *setvalue crosssections id=$secID Axis_Node_N3= { nodes $Ax_N3 }

 

Kindly help me to change the data of the crosssection like 

Three Nodes N1,N2,N3 and grshel_ID

 

i attached image for your reference

Please try changing {nodes $Or_N1} by 'nodes $Or_N1'

And also for n2, n3
