INITDIS (Initial Displacement Condition)

Description

The INITDIS entry defines values for the initial translational displacement.

Format

1	2	3	4	5	6	7	8	9	10
INITDIS	TID	SID	Dx	Dy	Dz	TYPE

Example

INITDIS	10	8	0	12.5	-5.0	GRID
INITDIS	88	9	-100	0	0	PART

Field	Definition	Type	Default
TID	Identification number.	Integer > 0	Required
SID	Set identification number.	Integer ≥ 0 or blank	0
Dx	Component of initial displacement in the global x-direction.	Real	0.0
Dy	Component of initial displacement in the global y-direction.	Real	0.0
Dz	Component of initial displacement in the global z-direction.	Real	0.0
TYPE	Type of Set. Choices are: ALLGRID – All grid points in the mesh are given the initial displacement. For this case the SID is ignored. GRID – All grid points in the set defined by SID are given the initial displacement. ELEM – All grid points in the set of elements defined by SID are given the initial displacement. PART – The SID is interpreted as a property ID and all grid points in the elements that use this property ID are given the initial displacement.	Character	Required

Remarks

1. Initial condition sets must be selected with the Case Control command IC = TID.
2. If no TIC set id is selected in the Case Control Section, all initial conditions are assumed zero.
3. Initial conditions for coordinates not specified on TIC entries will be assumed zero.
4. If the SID references a grid point that is the reference node for a rigid body defined with an RBE2 entry and the PART specification is used for TYPE, the initial condition is applied to the reference node for the rigid body.
5. If the SID references the material identification number on a MATR1 entry (the MATR1 entry defines a rigid material) and the PART specification is used for TYPE, the initial condition is applied to the center of mass of the rigid material defined by the MATR1 entry.
