    Hi, I was hoping I could get some help. I've been trying to run FLUIDOS for a few days and it's been crashing every time. I tried the first example  in the manual a few times and then I downloaded the honey scene from Renderosity and tried that several times. No luck, it jsut keeps crashing DAZ (once, it crashed and wouldn't open DAZ at all until I restarted the computer, which was a very weird experience on a mac).

    I'm on a Mac M3 with DAZ Studio 4.24.0.4 .

    The logs from DAZ:

    Is OpenCL enabled (in the Fluidods Domain)?  If so, disable it . OpenCL might not function on macOS, as it was deprecated for recent macOS versions.

    What is the Fluidos II edition you have? LITE, Complete, an upgrade?

    Hoping maybe someone can explain what I'm doing wrong or if I missed something. I'm trying to test running fluids through a pipe and well...it's not working.  I have a screenshot of what it does with the prop loaded in at default, and another after I used the thickener plugin on it. Most of the fluidos values are at default, except I turned on viscosity. I do have everything parented to the domain that needs to be.

    How does the cell size compare to the separation between the layers of the pipe, or even the diameter of the pipe?

    I was trying between 2.00 and 2.50 but it didn't seem to matter. I notice the liquid seems to just go through most geometry I try even though they aren't paper thin.

    Could you upload the .duf here so I could check the scene?

    Here you go. Very simple, I made a tube in zbrush but also used the thickener on it so you can test on both objects.

    I checked.  I changed the Cell size to 1.0. The results are in the uploaded image:

    The cell size must be smaller than the pipe wall thickness; otherwise, the fluid could filter through the wall.

    Another option is to increase the wall thickness.

    Ah ok, I understand now. I tried the wall thickness setting a couple times and I don't think i liked the results. I'll probably have to play with that more.  Thank you for your help.

    So, I was asking about it elsewhere, but is there a way to create a fluidos animated simulation in DAZ Studio, let's say it would be a 100 frame simulation, and then I could 'export' it by 'baking' the simulation as 100 unique per frame geometries?

    When you run a Fluidos simulation, the resulting geometries are saved ("baked") in a folder selected by the user. A Fluidos Mesher can point to this folder and reproduce the geometry without the need to redo the simulation.

    If you want to use the simulation outside of Daz Studio, an option is to export the geometry (as reproduced by the Mesher) as .obj files.

    Thank you for the lead!
