# Restart for Fatigue Analysis

Restart for fatigue analysis is available from linear static analysis results, local model results, and random response results.

## Fatigue Restart from Linear Static Analysis Results

An .h3d file containing results from a linear static analysis
can be imported into a dummy linear static subcase. A subsequent fatigue analysis
subcase can be used to conduct fatigue analysis based on the imported linear static
analysis results. The following example illustrates the
setup.

```
ASSIGN,H3DRES,10,linear_static.h3d
SUBCASE 1
ANALYSIS=STATIC
IMPORT(SUB=1)=10
SUBCASE 21
FATDEF = 100
FATPARM = 252
FATSEQ = 401
BEGIN BULK
FATSEQ,401
+,501,1
FATEVNT,501,601
FATLOAD,601,701,1,1.000,5.00,0.0
```

## Fatigue Restart from Local Model Results

(Imported global model .h3d-submodeling)

An .h3d file containing results from the global model
(submodeling) can be imported into a dummy local analysis static subcase which
contains the corresponding global-local interface setup via
SPC/SPCD with the M
option for mapping. For more information, see the Global-Local Analysis (Submodeling) User Guide. A subsequent
fatigue analysis subcase can be used to conduct fatigue analysis based on the
results coming from the local model. The following example illustrates the
setup.

```
ASSIGN,H3DRES,10,global.h3d
SUBCASE 1
SPC=11
IMPORT(SUB=1)=10
SUBCASE 21
FATDEF = 100
FATPARM = 252
FATSEQ = 401
BEGIN BULK
FATSEQ,401
+,501,1
FATEVNT,501,601
FATLOAD,601,701,1,1.000,5.00,0.0
SPC,11,1,123,M
+,GSET
SPC,11,2,123,M
+,GSET
```

## Fatigue Restart from Random Response Results

(Restarted from .h3d coming from FRF analysis results)

An .h3d file containing results from a frequency response
analysis can be imported into a random response subcase. Then a subsequent fatigue
analysis subcase can be used to conduct fatigue analysis based on the random
response analysis results. The following example illustrates the
setup.

```
ASSIGN,H3DRES,10,frf.h3d
SUBCASE 1
ANALYSIS=MFREQ
IMPORT(SUB=1)=10
SUBCASE 2
ANALYSIS=RANDOM
RANDOM = 100
SUBCASE 9
LABEL fatigue
ANALYSIS FATIGUE
FATDEF = 13
FATPARM = 15
FATSEQ = 23
Begin bulk
FATSEQ,23
+,24,1
FATEVNT,24,22
FATLOAD,22,,2
