Hi ANSYS Community,

I'm quite new to ANSYS, have been using it for a couple of months now, and searched for several times for a similar topic and wasn't able to find anything related to the specific issue.

I'm modelling an electrical transmission line tower and its foundations considering the soil structure interaction (SSI) using Winkler Model (Spring Model) for the soil. In the regard for the Winkler Model i have found very helpful guidance in topics throughout the community and i am very thankful for that.

The problem is, i'm modelling a tower that's quite big and so are its pile foundations. The foundations comprise of 176 piles with depths that vary from 25 meters for the pile caps and 20 meters for the ground beams. Since I have to insert a spring every half meter of the pile for the Winkler model and that gives me a total of 16960 springs and I'm attaching every single spring directly to the respective mesh node of the pile in that specific depth (I haven't been able to find an easier way of doing it) it has been very annoying to do so, and that's not even the worst part. As I insert more and more springs it becomes more and more slow to edit things in the Outline, I tried to do everything to improve Workbench's performance but had not been able to do so. ANSYS isn't consuming all the RAM, or disk, or even the processor, i can manipulate the geometry quite quickly, Mechanical solves the model quite quickly also, the only problem that i have is that when i edit the Outline it takes like forever, it takes like minutes to add a new spring or to add anything to the model and given the number of springs to be added I'm starting to doubt that I'm going to be able to finish it in time for my presentation.

If anyone knows an easier way to do this, or some way of improving Workbench's performance i will be very much thankful. Any help is valid!

Just for information: the springs stiffness vary with depth and all the springs in the same depth have the same stiffness for all the piles. I haven't been able to find a way to define A body to ground spring and its direction (i need to apply 2 springs per node, one in the X and another in the Y direction) and applying it to multiple nodes, that would solve the problem but i don't even know if that's possible so right now i'm defini reference and mobile points for every single spring.

Sorry if the text is a little confuse, but english is not my first language. And thanks in advance for any help i mght get.
