Deformation of supports

[MartinSalak]

We would like to show you new SAF objects for imposed deformation of supports. We will keep our current format of loads and create two new objects; one for translation and one for rotation. For now in SAF, supports' axes are in the global coordinate system, so the deformation will be set only in the global directions for now.

We would love to know what do you think about it? Would you prefer to set coordinate system for the load rather than use the coordinate system of the support? Would you like the option to set the deformation in absolute values as well (for example 10 mm below global 0)?

Object: StructuralPointDisplacement
Displacement can be imposed in a direction of one of the local axes of a support in a node (StructuralPointSupport). Positive displacement acts in the positive direction of the corresponding axis. A rigid support is expected in the direction of the displacement.

Property	Example	Description
Name	TRS1	Human readable unique name of the force
Support in a node	Sn6	The name of the support in a node on which the deformation load is applied
Direction	Z	Specifies the direction of the deformation
Value [mm]	-10	Specifies the size of the deformation in the set direction
Load case	LC5	The name of the load case to which the load belongs to
Id		Unique attribute designation

Object: StructuralPointRotation
Rotation can be imposed around one of the local axes of support in a node (StructuralPointSupport). Positive rotation acts right-handed about the corresponding positive axis. A rigid support is expected in the direction of the rotation.

Property	Example	Description
Name	RS1	Human readable unique name of the force
Support in a node	Sn6	The name of the support in a node on which the deformation load is applied
Direction	Rx	Specifies the direction of the deformation
Value [mrad]	-10	Specifies the size of the deformation in the set direction
Load case	LC5	The name of the load case to which the load belongs to
Id		Unique attribute designation

Let us know what you think!

Hi @msalak-scia, let's put these two proposals together in one object.

[MartinSalak]

New object is implemented in the latest version of documentation which will be release with the next version of SAF, take a look:

What do you think? All comments and notes are welcome.
