Implementation of a NeoHookean hyperelastic material.

Attribute	Format	Default	Description
young_modulus	float	1000	Young’s modulus of the material.
poisson_ratio	float	0.3	Poisson’s ratio of the material.

Quick example

XML

<Node>
    <RegularGridTopology name="grid" min="-7.5 -7.5 0" max="7.5 7.5 80" n="9 9 21" />
    <MechanicalObject src="@grid" />
    <HexahedronSetTopologyContainer name="topology" src="@grid" />
    <NeoHookeanMaterial young_modulus="3000" poisson_ratio="0.49" />
    <HyperelasticForcefield topology="@topology" template="Hexahedron" printLog="1" />
</Node>

Python

node.addObject("RegularGridTopology", name="grid", min=[-7.5, -7.5, 0], max=[7.5, 7.5, 80], n=[9, 9, 21])
