How to wedge one simulation at a time? Wedge taking too long

Hello,

I have 36 objects that I run through a vellum sim and adding some simple wind movements to them.

I am trying to simulate all 36 simulations with a wedge but I would like to run one sim at a time.

Each simulation takes around 30 seconds if I run it in SOPs. But when I wedge all 36 of them, they need the entire night because it runs multiple simulations at the same time.

How can I force the wedge to simulate one frame at a time and one iteration at a time?

Thank you

Click on the Scheduler and Review the Job Parms tab. Try activating the Single checkbox. This should force work items to run one at a time.

Hey Enivob.

So this is my first time using wedge nodes. Literally my second day now. I read somewhere about that single checkbox yesterda and I am not sure I activated it correctly the last time because I added it through the parameter interface but it was still simulating multiple frames at once.

Which one is the scheduler and where can I find the Job Parms tab that you mentioned?

Try the one in your screen shot. Local Scheduler

Ah, so that's the scheduler. I kept ignoring the node subconsciously. Thank you so much for clearing this up.

Alright so, it does only sim one frame at a time now, but it is simulating one frame per object.

So, it simulates Frame 1 for iteration 1 and then moves on to Frame 1 for iteration 2 and so on.

Doesn't that mean that when it goes back to iteration 1, it will have to calculate Frame 1 so that it can simulate Frame 2?

Or am I mistaken?

Because if that's the case, what I am trying to do, is simulate Frame 1 up to End Frame for iteration 1 and then move on to do the same for each iteration.

Also I wanted to add that if that's the furthest I can go with wedging, then it is extremely slower.

It takes around 30 seconds to sim 50 frames in the viewport and around 5 minutes with wedging.
