Cuda Solver info, Error Code: 13

[frascow]

Frascow, you may want to see what my last post that discussed the observations and workaround I did in re to cuda crashing.

Hi JonY

I actually tested your workaround, setting the multiplier on a very low value and it works, unfortunately on the scenes I usually work the sense of scale and right physics is completely lost with this trick. Thanks for it but I really need a better solution, I'm sure Tyson will find it, meanwhile I prefer to work with the version 0.16108 that I keep running on 3dsmax 2020

__________________________________

I have attached a simple scene that generate the cuda error code 13 on my machine.

In the 3ds max scene, a simple cloth sticking to a box, and colliding with a box.

When the physical size of collider box is large, cuda solver works fine. But when the collider box becomes smaller (thinner), that is when cuda solver runs into problem - ie no collision after N frames. This correlate to your IZ solver point raised in your earlier post.

What I observed is rather straight forward:

. When collider object is large enough in size to collide with cloth, cuda solver works fine.

. When collider object becomes finer and intricate in size, cuda solver will crash after N frames. The way round this to what I tested was to play around with the Force parameters, by reducing the Multiplier value mentioned in my earlier post. This at least works for the moment.  


Anomaly observed in Point Cache (for suggestions):

. Upon a successful cuda solver cache of Tyflow with Mesh as its last operation (with Render off), I inserted a Point Cache to record the full simulation as individual cache files.
. But when I reload the cache on a copied plane from the original, either:
   . the new plane with loaded Point Cache disappears and not seen in viewport
or
   . the coordinates of the loaded Point Cache gets distorted, eg rotated and away from the original coordinates where cloth simulation was performed

Hi there,

My values on TdrDdiDelay and TdrDelay are already 60, Redshift renderer asked long time ago to add those lines to the registry,
About OS, Windos 10 (Buid 18363) pro and 3dsMax 2021

At least it seems that we both have exactly the same problem.

thanks!
