How to Avoid dForce Simulation Crashes?

I recently purchased a dForce-ready hair model (dForce Classic Long Curly Hair) and am trying to drape it using simulation, but nearly every time I run the simulation, it fails — Daz simply quits unexpectedly. Daz support tells me it’s probably due to mesh intersection that happens during the simulation, a problem for which they offer no remedy. While I can do my best to avoid mesh intersection when, say, posing a model, I don’t see how to avoid it during a simulation.

This makes all dForce simulations highly problematic. There must be a better way to implement it than to just cross my fingers and hope I get lucky and avoid a crash. Does anyone have any tips or tricks on how to avoid mesh collisions?

Also, a related question: Would a better graphics card run the calculations with a higher success rate? Or is the crashing bug occurring purely within Daz itself? Does anybody know?

As always, I appreciate any insights the community has regarding this issue.

    You don't say what your current system setup is.  When you say "crash" do you mean "explodes"?  Or does Daz die?

    Sorry, I shoud have stated: I'm running Daz Studio 4.15.02 on a quad-core Mac Mini with 16 GB of RAM, and OS 10.12.6 (Sierra).

    Daz often quits unexpectedly during simulations, and also when I hit Save. It also sometimes quits unexpectedly during renders.

    Maybe this will help:

    Thanks Greg. I'll try using the CPU to run the simulations rather than the graphic card, and see if I get better results.
