Elemend ID of max failure Index

Felix Lentz_21924

Hi,

I'm performing a stochastical analysis and want to retrive the element id of the element with the max composite failure index.
Is there a possibility to define this Element ID as a response. The aim is to check, if the changes in material properties change the position of failure.

 

regards,
Felix

if you're reading a vector, you could use indexofmax (or something like this) to retrieve which index gives you the maximum value.

Remember that HyperStudy works based on 0 index, so that the first index is 0, not 1.

 

So if you have a big vector with FI for each element, let's say "ds_1"

ds_1 = {0.4 0.2 0.0 1.0 0.4}

Your response could be:

r_1 = indexofmax(ds_1)

will give you 3 as response. This is not the element ID, but the index of the i'th element in your list.

If your elements are renumbered starting from 1 and with no gaps, then your index would be equivalent to (ID-1)

Hi Adriano,

thanks for your quick response. The solution with indexofmax makes it possible to check if the failure occures at the same spot, that helps a lot. Because every Element has several composite layers which could fail it is not easy to determine the element id because I have a matrix of Element_id x Composite_layer and for other reasons it is not possible to have continuisly numbered elements.
