Hi,

I want to get total number of elements of a model.. Right now I'm marking all elements and using [llength $xyz] getting the total number of elements. But if number of elements are more, then it takes much time.. Is there any other faster approach to get the total count ?

Also, any command for 'elements by attached' ? Should select all the elements attached to it..

    Hi,

    Using Hypermesh GUI you can count no of element using Tools page:count option.

    Extended entity select option provide option for selecting elements by attached element. see screenshot.

    Hi Rahul,

    Thanks for the reply.. Yes using GUI we can do this, but I want to implement it in a tcl script.. It's not writing anything to command.cmf file either..

    Hi,

    using hm_count is faster

    or if you want to count entity in a mark, using hm_marklength

     

    do not use llength [hm_getmark elems 1] because it passes all entity ids into tcl interp slowly

    Thanks! It worked.

     

    EDIT: Is it possible to move elements present in mark ID 2 to mark ID 1 without affecting elements present already in mark ID 1 ?

    Like one component have two element type wiz S3 and S4.
