Minimum requirement for PC spec

[Brook]

Hi, I would like to know that what is the minimum requirement for PC spec that will achieve the 60 fps, the test case will be just a simple water pouring from one glass to another glass.

It depends a lot on:

- The resolution you wish your fluid to have, in particles per volume unit. Higher resolutions require more computing power.
- The timestep requirements of your simulation. Lower time steps require more computing power.
- How incompressible you want your fluid to be. Enforcing high incompressibility requires more computing power.

As a rough guideline, a Quad-Core i7 CPU can simulate around 7000 particles at 60 fps, using a timestep of 0.02 ms and 4 density iterations to enforce incompressibility.
