Why can't I make simulations anymore? Problem solved!

The picture linked at the bottom is nonsense, I know. It is only the first test of clothes that didn’t crash

DAZ-Studio 4.24 on my „new“ iMac (actually it is a late 2013 iMac I bought on

Ebay because of the inbuilt Nvidia graphics card).

Every other attempt to simulate a figure with dforce clothing shut down the application

immediately.

I have looked in the forums if someone else has the same problem. But it doesn’t seem

to be a known problem.

I have deleted Vers. 4.24 and changed to the old version 4.20.

At least there is the Save Menu accessible during the simulation (which was sometimes very helpful).

But a new simulation shut down another simulation with the old version of the program.

So I can’t find out what the incompatible components are; the system (Sonoma 14.7),

the application or the graphic-processor (Nvidia GeForce GTX750)?

 

As far as the picture is concerned: P3D Ursula G9, Fair Maiden Dress, Elysianna Hair

BM-6 Bird Props, Some parts of the Hobbit home by Roguey and some other props

Just to see if she model could be rendered. At least that worked well.

After 4 or five attempts to make a simulation with the dress, I used a somehow

strange and seemingly un-technical solution: I let it „sink in“ (in the brain of

a computer?) I didn’t start the simulation right after opening the file, instead I waited

for some minutes before I hit the simulation button - and it worked! 1 time!

Every other attempts with different models caused a crash of the application.

 

Now my question is: has anybody had the same problems or maybe someone

has found a way to get around it?

Thanks for reading!

I don't think it is clear to me.

Is it Daz Studio that is crashing when you try to simulate?

If you create a sphere and a plane with e.g. 50 divisions. Then raise the plane over the sphere and add a dForce modifier to it and simulate.

Will that work?

Thanks, felis! That is the fist thing I tried after some crashes. And that simulation worked well.

Some crashes later with the model you can see in the picture I have tried this:

Evry other try caused a crash of DAZ-Studio. 4.24 as well as 4.20.

But when DS crashes, does it then come with an error message that DS has crashed or what?

No, the crash-log said something about the Nvidia Processor (that I could not understand - all techno-blah) BUT:

It seems, I found the solution: let the CPU do the dForce-Simulation.

At least on my iMac with i7-Processor:

> go  to the Simulation Pane > Advanced Tab > under  „OpenCL Device“ choose:

Apple Intel Core i7-4771 CPU @ 3.5 GHz

The simulations run nearly 2 times faster than the ones with the Nvidia Graphics Card Processor

AND it doesn’t crash the Application every time!

I don’t remember if I could have chosen the CPU with my older Mac. But I guess it was an i5 CPU.

And that was not ready for such tasks.

Good you got it solved.
