Script for exporting vonMises of components

Altair Forum User

Dear All,

In my current project I have 21 different components of which I have to obtain the average vonMises stress of the shell elements inside the components, resulting in 21 different values. I would like to run multiple analyses with different thicknesses and material properties. To make the process faster, I would like to create a TCL script which would be able to obtain the average vonMises of each component and write it out to a file. Could someone suggest a source that would help me get started?

Kind Regards,
Balazs

Hi Balazs,

 

You can check out scripts in Script Exchange, just filter out Hyperview as in attached image.

Do note that HyperView scripting does require practice in getting correct handles and hierarchy. I have written some easy scripts in this forums earlier which can be a good reference to begin with.

Dear Livil,
Thank you for your reply! I am trying to get a deeper look into the language, but I have met a barrier that you might be able to explain. I am trying to run the following code to obtain the element id and contour value:

 

hwi OpenStack

set t [clock clicks]

hwi GetSessionHandle session
session GetProjectHandle project
project GetPageHandle page 1
page GetWindowHandle win 1
win GetClientHandle anim
anim GetModelHandle my_model [anim GetActiveModel]
my_model GetQueryCtrlHandle my_query

 

set set_id [my_model AddSelectionSet element]

 

my_model GetSelectionSetHandle elem_set $set_id

 

foreach id 1 {
    elem_set Add 'id $id'
}

 

my_query SetSelectionSet $set_id

my_query SetQuery 'element.id contour.value';

my_query GetIteratorHandle my_iter

 

set data_list ''

 

for {my_iter First} {[my_iter Valid]} {my_iter Next} {
lappend data_list [my_iter GetDataList]
}

 

 

The problem that I run into, that my my_iter First is already causes my_iter Valid to be False, therefore I think something I am doing wrong with the selection of elements. Could you point me in the right direction with the issue? 

Thank you!

I have solved it myself with:

 

set set_id [my_model AddSelectionSet element];
 my_model GetSelectionSetHandle elem_set $set_id;
 elem_set SetSelectMode 'all'
 elem_set Add all;
