Hi there, I am trying to couple NASTRAN and MATLAB to run itiratively. I am using ! bang for running a batch .bat file which inturn runs the specified .bdf file in NASTRAN. Now, my problem is reading the required deflection and forces data from the nastran output .f06 file back into MATLAB. I am able to read the whole file with all that messy huge data. But I am not able to sort out only required numerical data from the huge data of strings n unwanted numbers.
kind help will be much appreciated.
Thanks

From the .f06 file description:
This is the main Nastran output file. It contains
the results of your analysis such as displacements
and stresses. It is in ASCII format so it can be
viewed in any text editor. It also contains
warning messages, error messages, and diagnostic
messages to help the user evaluate the quality of
the analysis results.
It is a text file that could be opened with textscan(), importdata(), and the like. What function are you using? From your post I am guessing you are reading it as binary data. Another possibility is that the text file and Matlab are using different encodings, so you could check for that.
I have never worked with Nastran, but I imagine that there will be some structure to how the text data is stored. Then you would need to pass the proper arguments to your import function.
If your question is how can I automagically import .f06 data to Matlab then then answer is you can't (as far as I know, but you could always look in the file exchange). I am afraid some effort might be required.

could you please describe how you were able to solve your stated problem (reading an .f06 file in MATLAB), so others can learn from it?

I created a Matlab function that is getting the f06 and reads the data line by line in a while loop and then uses textscan() to read the displacement, stress, and other outputs and it does this automatically. Even though the geometry is changing in every iteration, it can read the f06.

Goodmorning, I would be interested too if you could share the code. Thank you

Use the nastran .pch instead of the .f06, the output data is more structured and easier to read. Otherwise, PYnastran could be of help to directly read in the binary .op2 file.
