The fluid simulation plugin for Carrara, FLUIDOS 1.4, is released now for both Windows 32&64bit and Mac since v1.4.
A free christmas present by Alvin Bémar at ShareCG: https://www.sharecg.com/v/90155/view/9/Plug-in/Fluidos.
Includes a detailed and updated manual, several test scenes and support for some AMD or NVIDIA graphics cards for acceleration.

• Version 1.00 was released 2017-12-24.
• Version 1.01 was released 2017-12-26, update if you got FLUIDOS early due to a bug.
• Version 1.1 was released 2018-01-24 with the following change log:
  -Now, the depth in hierarchy is unlimited. Anything can be parented inside the Fluid Domain at any level.
  -Fluid Domain can be scaled using Overall (or its equivalent in Scale tool).
  -FluidS now can resize the diffuse particles (the default is 1.0)
  -A Range force slider allows to “thicken” the extent of the surface forces to one or two cells away the solid (default is one).
  -The user could now turn off OpenCL.
  -It was implemented three more GridFluidSim3d diffuse particles features: maximum lifetime, wavecrest emission rate, turbulence emission rate. The default values are the current ones in Fluidos 1.01
  -The manual is updated.
  -Some bugs fixed.
• Version 1.2 was released 2018-04-27 with the following change log:
  -Viscous fluids simulation available.
  -Some advanced features are now available.
  -FluidS modifier is faster.
  -The triangle diffuse particles geometry is fixed.
  -Triangle particles can be oriented to camera now.
  -A memory leak in FluidS was fixed.
  -And some other bugs was fixed.
  -The updated manual explain details. I add two scenes in the files. In addition, there is a template for texture maps in shaders for the diffuse particles triangles.
  -The version is for Windows 64 and 32 bits too.
• Version 1.3 was released  2018-07-21 with the following change log:
  -Faster and less memory needed for objects only partially inside the Fluid Domain
  -Added an adjust factor for high precision viscosity simulations.
  -The smoothing is better in the interfaces liquid-solid when there are curved obstacles (smooth the “stairs”).
  -Expanded the limits of particle emission rates sliders and Smoothing iterations.
  -Reduced the limits of Particle jitter factor to avoid crashes,
  -Reorganized the Fluid Domain parameters tab.
  -Added functionality for animated solids (they can push fluid now).
  -Added functionality for spatially variable viscosity
  Bugs fixed:
  -Flow force didn’t work in many scenes.
  -Point force didn’t work properly as square inverse (this was a subtle bug).
  -If an obstacle with a surface force was initially outside the domain, the plugin stops with an error when the obstacle reaches the domain.
  -Every second frame, the body forces (gravity) were applied two times.
  -If the chosen preferred device was CPU and the simulation was stopped and resumed, the device automatically was changed to GPU.
  -Diffuse particles simulation sometimes could crash the plugin.
  -CFL condition number didn’t work properly
• Version 1.4 was released  2019-01-08 with the following change log:
  
  New Features:
  • Anything is source: any object can be a source (or a sink).
  • Cuboid source and Anything is source can be spatially discontinous.
  • The OpenCL simulations are around 30 % faster.
  • The simulations can use presets.
  • Line forces.
  • Spatially variable viscosity now with viscosity controls.
  • New options for objects parented to Fluidos Domain (viscosity control and ignored).
  • Support also for MacOS 64 bits.
    Fixed these bugs:
    • Some graphics cards were incompatible with the plugin.
    • Diffuse particles quantity sometimes decreases during simulation and, then, suddenly increases to limit in one frame.
    • Positive surface forces were insensible to intensity.
    • Simulations with moving obstacles enabled, sometimes are unstable (disproportionate turbulence, explosions, etc.)
