Material

  • Material Type

    • Fluid, sand, elastic body, or snow.

  • Density

    • The density of the material, measured in kg/m^3. Common materials such as water have a density of 1000.

  • Young's Modulus

    • The Young's Modulus of the material. Measured in MPa. For materials similar to jelly, the Young's modulus is usually between 0.01Mpa ~ 1MPa.

    A higher Young's modulus may cause simulation explosion. In such cases, reducing the time step of sub-steps in Soft2DManager (see Soft2DManager) can prevent simulation explosion. However, please note that a very small time step of sub-steps could lead to performance reduction.

    Fluid itself does not possess a Young's modulus property. In this plugin, the Young's modulus of fluid is used to indicate the incompressibility of the fluid.

  • Poisson's Ratio
