For manual entry, please note that real-world viscosity (the so-called dynamic viscosity) is normally measured in Pascal-seconds ($$Pa\cdot s$$), or in Poise units (P, equal to 0.1 $$Pa\cdot s$$), and commonly centiPoise units (cP, equal to 0.001 $$Pa\cdot s$$).

Blender, on the other hand, uses the kinematic viscosity which is the dynamic viscosity divided by the density, $$\frac{Pa\cdot s}{kg/m^{3}}$$, which is $$m^{2}/s$$. So for example, the viscosity of water at room temperature is 1.002 cP, or 0.001002 $$Pa\cdot s$$; the density of water is about 1000 $$kg/m^{3}$$, which gives a kinematic viscosity of 0.000001002 $$m^{2}/s$$ -- so the entry would be 1.002 times 10 to the minus six (1.002×10-6 in scientific notation).

Tip

You can find the kinematic viscosity of more materials in the proper units by asking Wolfram Alpha, e.g. "kinematic viscosity of alcohol in m^2/s".

The exponent of the viscosity value that will be multiplied by 10-1 (e.g. 6 in the case of water (20 °C)).

Note

Blender中的默认值被认为是这些类型的流体的典型值，并且在动画时 "看起来正确" 。然而，某些流体的实际粘度，特别是巧克力糖浆和蜂蜜等含糖液体，在很大程度上取决于温度和浓度。油粘度因：缩写：SAE（汽车工程师协会）评级而异。室温下的玻璃基本上是固体，但1500°C的玻璃像水一样流动（几乎）。

Warning

## 高粘度解算器#

The high viscosity liquid solver can be used to simulate fluids with increased viscosity, replicating the behavior of substances like honey or molasses. This specialized solver enhances the accuracy of slow-moving and thick liquid simulations.

Note

A strength value of 0 will still apply some viscosity. Uncheck the High Viscosity Solver to disable the high viscosity liquid solver simulation step completely.
