Hello,
I am trying to extract the global stiffness matrix from Ansys. I am using the following command to do so:
*DMAT, MatKD, D,IMPORT, FULL, file.full, STIFF
*PRINT,MatKD, K.csv
When I open the file, I see that the matrix is printed with the index numbers as well (screenshot attached). Is there any way to print just the values? and also not have the matrix name "MatKD:" at the beginning?
Look, it seems that your data output follows a regular pattern like: a number enclosed by brackets, a character ":" followed by a number with 4 significant digits and a power of ten.
What I would do is to write a quick parser script using Python or Matlab and RegEx to extract the necessary patterns from the CSV output. For example, the following RegEx seems to match all the numeric values shown in your picture, after the placeholder ":", positive or negative:
:?[0-9].[0-9]{3}e.[0-9]{2}
@Amauri Martins-Britto, Thanks for the answer! I did exactly the same thing. I was just wondering if there is a direct way to do it, that's all.
Sorry Nils, I could not get back to you. The problem is solved now. Thanks!
@mehnuma Tabassum can you please tell me how did you solve this problem?
