SI Unit Example

impvel_ID

Imposed velocity block identifier

(Integer, maximum 10 digits)

 

unit_ID

Optional unit identifier

(Integer, maximum 10 digits)

 

impvel_title

Imposed velocity block title

(Character, maximum 100 characters)

 

fct_IDT

Time function identifier

(Integer)

 

Dir

Direction: X, Y, and Z in translation; XX, YY, and ZZ in rotation

(Text)

 

skew_ID

Skew identifier

(Integer)

 

grnd_ID

Identifier of the node group on which the imposed velocity is applied. Input is obligatory. The imposed velocities will be applied only on nodes that belong to a node group.

(Integer)

 

Ascalex

Abscissa scale factor for fct_IDT

Default = 1.0  (Real)

 

Fscaley

Ordinate scale factor for fct_IDT

Default = 1.0  (Real)

hmtoggle_plus1Comments
1.The velocity direction must be right justified in the ten characters of field number 2.
2.The translational velocity is not available, if it is applied on a node with a null mass.
3.The rotational velocity is not available, if it is applied on a node with a null inertia.
