Running all Nastran input .bdf files contained in a folder using Matlab

Hello everyone,

I am trying to run a number of nastran input.bdf files contained in a folder using "system "command in matlab

System command works well when i secify onle one file named"1.bdf" like:

system('D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe 1.bdf')

But,I have three bdf files in folder, I am trying to run using for loop

I have tried:

..................................................................................

files = dir('*.bdf');
for i = 1 : length(files)
  filename = files(K).name;
  system('D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe filename')
end

.......................................................................................

But it does not start nastran ,rather gives output such as

ans=0

ans=0

ans=0

files = dir('*.bdf');
for i = 1 : length(files)
  filename = files(K).name;
  system('D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe filename')
end

in

system('D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe filename')

'filename' is contained in the literal string, not the variable filename

cmd=['D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe ' files(K).name];
system(cmd)

Depending on system path and where files are located, you might need to pass the fully-qualified name as well...

cmd=['D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe ' fullfile(files(K).folder,files(K).name)];
system(cmd)

Be sure to change i and K to k.

files = dir('*.bdf');
for k = 1 : length(files)
  filename = files(k).name;
  system('D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe filename')
end

And to just make super sure that the executable has the full filename of the both files you should do

executablePath = 'D:\MSC.Software\MSC_Nastran\20180\bin\nastranw.exe';
dataFilePath = fullfile(files(k).folder, files(k).name);
commandLine = sprintf('%s %s', executablePath, dataFilePath);
system(commandLine)
