Most Efficient Way to Select Elements with Multiple Selection Criteria

Ryan_20869

Hello,

Hoping someone can help me find the most efficient way to select elements with multiple selection criteria -

 

i.e. I want to select all of the elements within a specific component, then further refine the selection to only select the quad4 elements.

I don't think hm_createmark can take multiple arguments, but if it could, an ideal solution would look something like:

hm_createmark elements 1 "by config" "quad4" "by comp" ID#...etc

 

I'm getting by with this, but this is rather slow for large models and seems limited in the number of conditions:

hm_createmark elements 1 "by config" "quad4"

hm_createmark elements 2 "by comp" $comp

*markintersection elements 1 elements 2

 

Thanks in advance!

Hey Ryan,

*markintersection has to go over all entities in both marks to get the common ones. I can see how this might take a long time if for the first mark you're getting all quad4 elements in the model and comparing only to all the elements in one component. 

Here's my suggestion: create a list with all the elements in a given component. So you'd use "hm_createmark comps" then "hm_getmark elems".

Using a foreach loop, check for every element if that's a quad4 or not. If it is, append it to an empty list. This way you only need to go over the elements in the component of interest.

Kind Regards,
