    weird, it works now. not sure why i was having so much trouble before. Thank you guys for you help! Just one quick question: does the source won't work if its in a tunnel that is too small for the source?

    You can reduce the source size to fit in the tunnel.

    Tips: the cell size must be smaller than the tunnel diameter, the half or less. The width of the walls of the tunnel must be at least twice the cell size.

    You're welcome!

    If fact, the last Fluidos version (1.3) already has a MacOS version. smiley

  • I have this plugin since release and I must say I still don't get everything. Is there any sort of configuration that determines the flow rate among a surface, for example? Like hydrophobic x hydrophilic surfaces? I know you can control overall fluid viscosity, but in case I wanted the same fluid to interact with two different surfaces, is this possible?

  • Every simulation I ran seemed like the obstacle was always too hydrophobic, there were almost no droplets left, even with small cell sizes (like .4) and subd 3

    Use Body Force for that. You can find the option among the Fluidod ones in the obstacle. Also try using a bit of viscosity.

    With the right parameters you can obtain your effect. Sadly, after lots of experiments I can tell there isn't an unique setup, you must find your for your scene.

    Yes, the fluid tends to behave as if the objects were hydrophobic. At this Fluidos version, there is not a option to transform the surfaces to hydrophilic ones. But there are some options that can help (you can one or both):

    • Increase the Surface smoothing value and the Smoothing iterations.
    • Enable the surface force in the solid. Use Intensity values lower than gravity, maybe 5, and Range Force = 2.

    The results are better with lower cell sizes and subdivision level  = 2 (or 3, but no more).

    Thanks, that actually helped a lot! Have you ever encountered a point where after many modifications and re-simulations, the plugin just stops updating? Like, it just keeps repeating one simulation result, even though you change the sources' positions?

    Sometimes, it is because I changed the Baked files folder in the Domain, but didn't change in the mesher to the same.

    Or could be that I ran e.g., 60 frames the first time and later I reduced the simulation to 30 frames (here is better to erase the extra files, or to enable Erase baked files before running).

    Or could be the inverse, e.g. first 30 frames and next 60 without updating the Mesher (disabling and enabling it again).

    Or sometimes, I changed the e.g. sources' positions at a frame 30 instead at the frame 0 as I intended.

    If you have more problems about it, let me know.

    Shower setup

    You can use any shower prop you wish.

    The .duf attached to this post contains a basic setup of a shower.

    The shower itself is an arrangement of two concentric cylinders. The internal is the geometric node for the Fluidos Source "Any node" type. The external one is an obstacle node to asure the fluid flows from only one face of the internal cylinder. 

    The cyan line indicates the flow intial direction. You can increase or decrease the velocity by changing the Velocity (y) in the Fluidos Source.

    Move to overlap the shower prop you want. Rotate the external cylinder to get the desired orientation and resize both if needed. Make the cylinders invisible.

  • I purchased this last week but although I have a serial no only 2 files were available to download - a content file of 131 mb and a tutorials file of 123 mb. I have looked through both and there is nothing in them that goes into a plugins folder so there is no way to register it

    in the content folder there are folders for props scenes scripts shader presets data runtime and readme but nothing for plugins

    The plugin itself is installed only via DIM. But if you want to install manually, there is a way: https://www.daz3d.com/forums/discussion/comment/3922111/#Comment_3922111

    Hi Alberto.  I was trying to use the settings from the soda can on a G8M and evertytime I I try to run the simluation Daz instantly crashes.  I am on the current public build.

    Hi, Sorel!

    Could you show me the Daz studio report and the Fluidos log file (it's in the subfolder "logs" of the Baked files folder), please?

    I see the problem.

    Your cell size is very small (0.1), the plugin has to create a grid of 1999 x 1999 x 1999 cells. Only the initialization needs to allocate more than 100 GB of RAM. After the initialization the fluid particles themselves will need more RAM, but your computer crashed before that step.

    Advices:

    • Increase the cell size. Halving the cell size increases eightfold the RAM to be allocated. For you domain, a 0.2 cell size will need about 13 GB; a 0.4 cell size, about 1.6 GB, and 0.8 cell size only will need 200 MB. Although the fluid particles themselves will need an additional RAM quantity, as in your scene the fluid quantity will be a small amount, this is not a problem. The drops diameter will be about the same of cell size (in centimeter units), but you can reduce something by reducing the Marker Particles scale in the Advanced properties.
    • Reduce the domain size. There are many empty space because you used a cubic domain. Reduce the x and z sizes. Try to wrap only the figure, or better, the body parts you desire.

    Yeah I figured out it must have been the cell size cause after increasing it it started to work haha.  Thank you for the advises.

    Another question, I may have missed it somewhere, what were your settings to make the tear from the eye?

    Thanks again!  I've had this plugin for months but am just now really starting to experiment with it lol.

  • Hello I was referred to this post luckily. Hopefully you can help me. First time using the Fluidos plug, and I think I got most of it figured out, but when I tried to render it, it came up a mess. Also think some reason the baker file is missing or I'm not using the right folder.

    In the image, the big white block was suppose to be a beach.

    Could you show me a snapshoot of the Viewport, please?

  • Unfortunately I don't have that file saved anymore. I did try to recreate a smaller scale but actually failed even worse lol.

    In the newer scene I did get the beach to show up correctly this time though, but couldn't get the water to move this time not sure why. It also still shows up white. When I load the preset for the simulation, only file I'm able to load is the one called autosave. All the other folders are empty.

    Let me see.

    You have a Domain with a source and a sink. Your simulation ran for 31 frames, OK?

    Try to set Completion  (in the Mesher) to 0 at frame 0 and 100 % at  frame 31 (enlarge the time by setting 32 in Total.  After this, you should see the animation. When the Number of frames says 31 frames, this includes the frame 0 to the frame 31 (32 frames in total).

    You don't need to load a preset for your simulation (that autosave is a backup of the simulation so you can resume the simulation).

    Apply a water shader to the Mesher (https://www.daz3d.com/forums/discussion/163801/how-to-apply-iray-water-shader)

    If that didn't work, let me know, please.

  • Sorry late reply, been busy lol. Thanks for the tips and they did help and looked better then before. The shader that comes with the Fluidos pack though still comes up only white like in my original post. This image I used Daz Original water shader though. How can I make the water bounce off the beach though? I tried making the beach a solid object in the scene parented to the domain and still didn't work. Thank you for all your help.

     The shader that comes with the Fluidos pack though still comes up only white like in my original post. 

    It's because the included shader is for Diffuse Particles (foam, bubles and spray).

    The beach must be a solid object, yes. Be sure that its width is larger than the cell size to be detected.

    You're welcome.

    I cannot believe I didn't realize this I bought it on the day it was released but I had to get a credit because I'm on a Mac. I've never even looked at it since. I'm so annoyed for not checking again especially since it was on sale the other day! *BIG SIGH*

    In each case the surface was projected inward as well as outward, so didn't look right at all, even assuming I wasn't still getting clipping.

    Again, if there was some way to thicken only outward or to somehow define a more firm barrier, that might do it. As it is, though, I found myself unable to get 'liquid in a bottle' to work at all.

     

    Do you think this is weird?
