Thanks for your help so far! One additional question I read the description in the link you referred to (Karamba 3D manual). And it is was mentioned that elements are not ‘‘really’’ removed but assigned with a very negligible stiffness (soft-kill approach). Considering '‘Force Follows Stiffness’, these elements with very low stiffness will attract (almost) no loading, but does this also mean that they are skipped in the next iteration, or are all elements (even the ones with the assigned negligible stiffness) assessed again?
So you import a domain of 1…n elements, you check them all and ‘‘remove’’ tension elements, but they are not physically removed. Does the domain remain 1…n meaning that all elements are assessed again, or is it reduced to 1…m elements in which m<n. Meaning that the elements with the negigible stiffness are not considerd. Please see the scheme I made:
Nb is the normal force to be assessed, and I am checking and eliminating tensile forces. i stands for the iteration number. 1…n is the domain at the start. you check all elements ‘‘b’’ step by step and update the domain based on ‘‘removed’’ elements. If the domain length does not change, no elements are removed and no tensile forces were found.
In summary, my questions are:
(1) does the TC eliminator consider all imported elements each iteration, or is the domain updated?
(2) additional question: if all elements are considered again and again, can elements also be added during the iteration process, or only be removed?
Thank you very much for you help!
