StructuralPointSupport

Support in node

StructuralPointSupport represents a support of the analytical model in a node. The support is defined by six separate parameters. Each parameter defines the constraint in one direction: translation in the direction of the X, Y, Z axis and rotation around the same axes. A nodal support is oriented in the global co-ordinate system.

yes

Translation in X direction. Free - That is it imposes no constraint in the direction.

Rigid - The support in fully rigid in the specified direction.

Flexible - The support is flexible (elastic) in the specified direction. Parameter Flexible can be linear only, non-linearity is not supported. Compression only acts only under compression. If the support gets under tension it stops acting. Tension only support acts only under tension.
