Need to create a batch file- I am new

 DB -
I am new in using batch files. I was looking into the forum and in the web I did not found any useful information.
my first question is :
I have a lot of BDF file ( bulk Data file) that I need to run it with Nastran. I would like to create a simple batch file ( call file one by one and run it with Nastran). Any suggestion will be very helpfull.

the second one:

I need a batch file to extract result data from a lot of text file.

Thank you for your help

Just open a notepad

Type the installation path of your nastran

Installation_drive\MSC.Software\MSC_Nastran\20101\bin\nastran.exe "Complete path of your file to be solved(including .filename.bdf)"

Similarily enter all the other files in the same format in the consecutive lines

Once this is done save the file and change the extension as .bat

Just run the .bat file

I will solve all the files in the order entered.
Thank you

A few words of thanks would be greatly appreciated. Add comment

Here is an alternative. It will feed all .bdf files under folder "C:/path/to/bdf files" to nastran.

# Script nastran.txt
var str list, file
lf -n "*.bdf" "C:/path/to/bdf files" > $list
while ($list <> "")
    lex "1" $list > $file
    system nastran ("\"jid=\"+$file+"\"")

Script is in biterscripting. Save the script in file C:/Scripts/nastran.txt. Call the script by entering the following command in biterscipting.

script "C:/Scripts/nastran.txt"

Now, in terms of,

I need a batch file to extract result data from a lot of text file.

Can you please elaborate ?
Hi there,

Since I am not sure how Nastran works, I can help you to get the files one by one. Please find the script below,

Includes two batch file,

1. To list all the files into a text file
2. To keep removing the first line (first file name) from the txt file.

Note: For your purpose, you have to work with the first file name where I have commented using rem command before calling the second batch file

first batchfile:
@echo off

if not exist ff.txt (for /f "tokens=* delims= " %%h in ('dir /b/s "C:\Documents and Settings\603389649\Desktop\test1" ^| find /v "*.dat"') do echo %%h >> ff.txt)

for /f "delims=" %%x in ('type ff.txt') do (
set h=%%x
goto hh

rem here I have printed the file name one by one
rem If you know how to use it with Nastran, use it here.
echo %date% %time% %h% >>file.txt
echo -------------------- >>file.txt

call dell.bat

Second batch File: (dell.bat)

rem This is to remove the first line from a file

@echo off

for /f "skip=1 tokens=*" %%A in (ff.txt) do echo %%A >> d2.txt
del /q ff.txt
rename d2.txt ff.txt

Please let me know if you have any problem

Thanks fro Help, but it didn't work.

I called Nastran from command prompt and now I have to find out how to include all the input file name.

thanks again and I will let you know
as I tried that you should run the nastran with .dat file and this .dat file must includ the .bdf file
but you need to learn how to creat the.dat file
