Nvidia rtx 4090 driver issues? Dec. 21, 2022, 2:04 p.m.

This is still an issue with vellum grain in my case, I am using H19.5.458, rtx4090 driver version 527.26. Inside vellum solver, the ocl_neighboursearch_grains node complains NAN particles position. Unchecking opencl neighbour search can get rid of the error though.

Particle number reduced in sliced FLIP Sept. 13, 2014, 1:22 p.m.

I distributed a FLIP sim on the farm, I noticed that particles flow towards the slices edge and disappeared (leaking?). Two problems arise as a result of this:

1. Velocities appeared along the slices edge, thus whitewater particles could appear unintentionally.
2. Water level dropped as the simulation went on because the number of particles reduced.

I tested using one machine with no slices, there was no leaking.

Maybe I can add particles to the container to keep the amount of particle during simulation but I'd like to know is this “leaking” normal when using sliced sim? Can anyone suggest some other solutions?

Thanks in advanced.

how to get dop field data from constraints in H9? Nov. 15, 2007, 10:51 p.m.

Hi,
In H8, constraint data is added as subdata under the dop object , but in H9, the constraint data is added under RelInAffectors and RelGroup, when query these two by dophassubdata(), it shows that they are not subdata. Since they aren't subdata, I failed to access any data under them.
For example, I have a wire object and I saw the following structure in the detail view: “RelInAffectors/wireSpringConstraint_applyrel5_0/Constraint/State”
inside State, there is “force” property I want to access, but I can't by using dopfield().
Can anyone give me some help…?
