Read the .str file that contains the solution vector x of the system of linear equations Ax=y.

Export the .str file using one of the following workflows:
• Use the PS card in EDITFEKO.
• Saving the .str file in CADFEKO.

The .str file is saved as a binary file, but can be converted into ASCII format by using the str2ascii utility. When using the “-r” option, a special .str file format is created that allows the re-import of the file into Feko. This gives you the power to visualise, for instance, characteristic modes.

Use the syntax:
str2ascii <filename.str> -r > ascii.str

This results in a file ascii.str with an ASCII format of the .str file which Feko can read again. The file contains the complex basis function coefficients in real and imaginary format.
