dForce Simulation Duration

Hello Friends,
I was checking this dForce cloth. I tried the SIMULATE command. However, my DAZ Studio crashed. The second time, the complete studio did not respond. I had to close the process and lose all the changes that I made. I am sad. But I need to move on, create from scratch. Can someone tell me how much time it needs to finish a dForce cloth simulation? And do I need a Graphics Card for quicker simulation?
Thanks and regards,
(The spell checker doesnt work here?)

It's not possible to say how long with any particular accuracy. Probably a few minutes, but it hugely depends on what's in the scene, your hardware and whether you've got smoothing modifiers active. (Which seem to be recalculated every frame of the simulation).
And yes, while it is possible for any device that supports OpenCL to run DForce, graphics cards are much faster at it.
And, I suggest from bitter experience of crashes, explosions & the like: ALWAYS SAVE JUST BEFORE A SIMULATION.
A GPU definitely helps with simulations, and it doesn’t have to be an Nvidia card, although it would be foolish to buy a non-Nvidia card if you’re planning to work with DS in Iray. As others have said, how long it takes will depend on a variety of factors, so no real answer can be given to that question. There are a number of things you can do to make dForce easier to work with, so that explosions and crashes happen less often, although I don’t know if one can eliminate them entirely.
I know it may seem like a hassle, but I find that grouping up anything unnessicary to the simulation and hiding them really improves my success rate when performing sims. In addition, if you have ONLY the things that you need visible when running it, you increase the chances of being able to recover if something like an explosion suddenly spikes the resource demand from your machine...
I also like to apply static modifiers to anything the DForced item will interact with. I don't know if it helps or if it's just in my mind, but making sure all dynamic items are ONLY interacting with static ones usually sees me success...
Neither of those answered your question.. unfortunately, that's like an IRay render... it's done when it looks right to you. If you're trying to hit the cancel button and it doesn't stop, it could be a resource issue, and in that case hiding items and minimizing your simulated polygons might help.
Thank you all for the valuable response. I am rendering on a basic laptop which has no GPU and an i3 processor with Intel Graphics. And I tried to hide and perform the Simulation. That did not help. I have never felt the need of my desktop so desperately. I just don't have space in my dorm to keep it. I am so angry. It's been kept completely packed in a box at my brother's house where it is serving as a shoe stand. As long as I stay in this dormitory, I can't get it back. It's been years....
I tried to simulate another frame with just one piece of cloth on Gen3. My simulation didnt even start and DAZ crashed. I think, my laptop is not meant to handle dForce. I will have to get my desktop somehow. I dont know if my GTX 1060 would be able to handle this.
Crashes are usually caused by the mesh, either it's design or how it intersects with a figure or other object. Can you post what you are trying to simulate? Also, I have an extensive thread with over 80 mini-tutorials on dForce you may find helpful. There's an index in the second post.
Hey, Thanks!
I have book marked your Tutorial. For now, I have parked dForce stuff. I will look into it once i get my desktop.
Hello,
I tried the dForce simutation test again today. It did not start at all. I am doing a simple scene. A plane falls on a sphere. The steps that i followed.
1. Created 2 primitives; a sphere and a plane.
2. Placed the plane above the sphere
3. Added dForce Dynamic Surface to plane
4. Did not touch anything else and hit the Simulate button
The result: NOTHING! DAZ stopped working. I have attached images for reference. Please notice the duration at the bottom right corner. I had to force stop DAZ through task manager.
What am I doing wrong?
That should be a simple simulation to run....
(LOL. I just did it and I can tell it's not going to work.)
Let's just say dForce can be extremely hit or miss, in my experience. Sometimes it's brilliant, sometimes it's the gift you never wish you received.
If you have minimal hardware, 3D work is going to be difficult. Rendering and Physics simulation most of all.
Yet, more and more clothing items are dForce now... Sad
I can render pretty fine. It takes time, but it does finish with a nice render. I dont have much pics here, but you can see my gallery: https://www.daz3d.com/gallery/users/198191
You're not doing anything wrong as that scene should work (and it does for me). Can you post a screenshot of your Advanced tab in the Simulations Settings pane. And what version of Daz Studio are you using?
I can, Do I need to recreate the scene and send the advanced tab settings? Or I can send it right away without anything in the scene?
I am using the latest version. 4.12
...there is the dFiorce Companion which as I understand makes it easy to just select a single item in a scene I picked it up on one of the coupon sales to test it out.

I give up! dForce is not my kind of stuff.
DAZ's recommendation for running DS is probably a bit outdated - 128 MB RAM (32 Bit) or 3GB+ VRAM (64 Bit). And 4GB+ VRAM for Iray. If your GTX 1060 is one of the older ones it could be the problem with dForce as the GPU carries the load with simulation.
Might be time for DAZ to up their minimum specs as they don't seem realistic given the demands that 4K textures, HD morphs and cloth simulation are now placing on the your rig. Sure you can still render stuff with those low specs, like you can hammer a nail with a screwdriver, but not recommended.
...for the most part not mine either, but too much new clothing content is being released with it (styles I wish were available in the G2/G3 days) so got the utility to experiment. If I still find it's too much of a bother I have 30 days to "return" it and any dForce clothing content I purchase. Can't afford the latest MD (the version I have is too old for the upgrade discount).
It's like back in the Poser 6/7 days if all clothing was Poser dynamic.
..128 MB of memory? Yeah, I'd say those specs are just a wee outdated. Crikey, on my old 32 bit Toshiba notebook I used to run Daz on had 4 GB of memory (no GPU) and it's 14 years old.
You do not need to recreate the scene.
I'm assuming you only have one Open CL device that will show in the advanced tab, but click on the dropdown box and see if there is another by chance.
fwiw all I have is a laptop with a GTX 1060 and I dforce all the things so it's very definitely doable
ohh, i m relieved! thanks friend :)
