A transient thermal analysis (ANTYPE,TRANS) obtains the temperature distribution, and a linear static analysis (ANTYPE,STATIC) obtains the residual creep strains in the lead-free solder.

The following input shows the solution commands used for the thermal analysis:

TRNOPT,FULL				! Specifies transient analysis options. 
TIME,150					! Final time for solution.
OUTRES,ALL,ALL		! Saved results at each substep.
SOLVE

The following shows the solution commands used for the structural analysis:

! RAMP (LOAD STEP 2)
NLGEOM,ON				! Includes large-deflection effects
RATE,ON					! Perform implicit creep analysis
TIME,150					! Set load step end time
KBC,0						! Loads are ramped
LDREAD,TEMP,,,TIME,0,'THERMAL','RTH'
SOLVE

! DWELL (LOAD STEP 3)
NLGEOM,ON				! Includes large-deflection effects
AUTOTS,ON				! Turn on auto time step
KBC,1						! Loads are step changed
TIME,450					! Set load step end time
SOLVE						! Solve load step
