Crashed with Nvidia OpenGL lost connection

[Ali Haider]

Hello

i am doing a fluid sim which is 400x100x800 around 81,361,150 particles , when i wanted to see its mesh it gives me an error and crashed, i wanted to tweak and render my ocean geometry for render but getting this stopping me from doing that.

My PC Config is

Intel i7 3770K (8 CPUs)3.5GHz

32 Gb Ram

GTX 570 HD

4049MB

Windows 7 Ultimate

Houdini 12.5.469

i am in the middle of somewhere any help would be highly appreciated.

Error is " The Nvidia OpenGL driver lost connection with display driver and is unable to continue. The application must close.

The resulting mesh may be too large for the card to handle. Since you're on Windows, the driver time limited recovery will reset the driver after 2s of the driver not responding, which looks like the case here. Try setting the cook mode to Manual and inspect the mesh size with MMB info. If it's too large (10's of millions of quads), adjust the surfacing parms to make a smaller mesh.

You can also change the Windows time limited recovery to a longer interval to avoid the driver reset. See the link here: http://msdn.microsoft.com/en-us/library/windows/hardware/ff569918(v=vs.85).aspx

H13 has better support for extremely large meshes which will avoid the driver reset.

It looks like the forum cut it off at the second ). Just add ) at the end of the URL and it should work. ie:
