IDs of attached elements

Merula_20758

Hey guys,

 

maybe one of you can help me completing the following task:

 

I need to know the IDs of the attached elements of elements. From a topology optimization I selected the elements:

 

 #Querry Elements set set_id [myModel AddSelectionSet element] myModel GetSelectionSetHandle elem_set $set_id elem_set Add 'contour >= $isoValue' myQuery SetSelectionSet $set_id myQuery SetQuery 'element.id element.centroid contour.value element.connectivity' myQuery WriteData $outPath/ElemsCentroid.txt

This gets me a list with ELEMENT ID, CENTROID coordinates, and the nodes associated with the element.

One way of solving my issue is to get a Node ID Element ID list. in order to find the attached elements. I really  cannot find the script to do this, as there is no node.connectivity query option.

 

Thanks in advance and best regards,

Merula

Hi Merula,

 

You can get the ID's of attached elements using the *findmark command. Here's a little test script I wrote as an example:

 # Create element set for test run *createmarkpanel elems 1 'Select Elements' set elemsOriginal [ hm_getmark elems 1 ]; *clearmark elems 1   # Find attached elements  hm_createmark elems 1 'by id' '$elemsOriginal' *findmark elements 1 1 1 elements 0 2 set elemsAttached [ hm_getmark elems 2 ]; *clearmark elems 1 *clearmark elems 2  puts 'The attached elements are $elemsAttached'
