.joint file

The .joint file is an ASCII format results file.

File Creation

This file is created when JOINTD and/or JOINTF I/O Options with OPTI option is specified in an input file which contains JOINTG. Refer to JOINTG Bulk Data Entry.

File Contents

This file contains the Displacements, Forces, and Moments, Reaction Forces, Viscous Damping Forces, and Stop/Lock Status in the joint for the final load increment for each JOINTG ID. Viscous Damping Forces are output only if the PROPERTY field on PJOINTG is set to DAMP. If NLOUT entry is defined, then intermediate load increment results are also printed in the .joint file.

File Format



Figure 1.

The .joint file has the following format.

For each iteration, the following header is used:
iter Iteration Numlds
Where,
iter
Keyword denoting the beginning of a new iteration
Iteration
Iteration number
NumIds
Number of load increments for which this output is created
Each iteration section is divided up by subcase. Output for each subcase starts with a line in the following format:
Id Number_of_els DISP:Spc_id (or)

FRCE:Spc_id (or)

RFRM:Spc_id (or)

SLST:Spc_id (or)

VFVM:Spc_id

 Nonlinear Load Factor: #
Where,
Id
Output identification number for the subcase. This is not the same as the subcase ID used in the input data.
Number_of_els
Number of elements for which this output is printed.
DISP, FRCE, RFRM, SLST, or VFVM
Keywords indicating that corresponding Displacement or Force results are printed.
Spc_id
SID for SPC's referenced by this subcase.
Nonlinear Load Factor: #
Load Increment at which the results are output.
