The number of parallels/users available at the same time has a limit.
If an error due to insufficient licenses occur, we may request you to cooperate with the use of your licenses.
## Software Overview{#overview}
MSC Nastran is a general purpose structural analysis program that allows users to analyze a wide range of data of a part to the whole. In addition to the existing analysis capabilities, the composite area simulation capability is able to conduct simulations in the area of high-standard implicit non-linear analysis including traditional linear static analysis, various dynamic analysis, design optimization analysis, thermal analysis, and 3D contact, as well as explicit non-linear analysis for high-speed phenomena such as collision and shock analysis and drop analysis.
### Software Features{#functions}
* Linear and non-linear analysis, static and dynamic analysis
* Real eigenvalue analysis
* Frequency response analysis
* Transient response analysis
* Random response analysis
* Acoustic-structure coupled analysis
* Impact analysis
* Optimization analysis
* Combining with Marc
* Combining with Adams, etc.
## How to Use{#usage}
### Setting Up Environment(Executing the module Command){#env-set}
Set up the environment by executing the module command. (Load the version of the module file which you want to use.)
```nohighlight
$ module load nastran
```
### Running in Interactive Mode{#tss}
#### Format
To start the program, execute the following command.
Please refer to [Interactive Processing](/run/interactive) for details on the tssrun command.
```nohighlight
$ tssrun nast input file [option ...] batch=no
```
### Submitting Batch Job by the subnastran Command{#subnastran}
The subnastran command is provided to make job execution simpler.
This allows you to run a batch job without writing an job script.
#### Format
```nohighlight
$ subnastran queue_name input_file [qsub option ...] [Nastran option ...]
Nastran option
smp=(The number of parallels) Shared Memory Parallel (default: smp=1)
```
#### Example
```nohighlight
$ subnastran eb d0307.dat smp=4
```
After the completion of the job execution, a new execution result file is generated in addition to the input file, as follows.
* Job processing result file
* B072615.o443917 ---- Standard output file
* B072615.e443917 ---- Error file
* Output file(Created with the same name as the input file name)
* d0307.f04 ----Execution summary file
* d0307.log ----Log file
* d0307.f06 ----Analysis result file
(Note) Please note that if you execute the job several times with the same input file name, a number of files numbered as follows will be created for each execution result files. If you execute a job four consecutive times, the file names will be shown as follows:
* Result file
* d0307.f06 (the fourth job, the latest)
* d0307.f06.1(the first job, the oldest)
* d0307.f06.2(the second job)
* d0307.f06.3(the third job)
