STR file currents
Good day,
Some people have suggested using a str2ascii utility to properly access the STR file. My understanding is that the str2ascii utility does no longer exist and there's a function integrated to FEKO to replace it. I'm using FEKO 7.0.2, and I am wondering if someone can teach me how to read the STR file.
In the quote below @RenierM briefly mentioned STR file contains 'matrix solution coefficients' - what exactly is this? Is this the currents matrix in the MoM matrix equation [Z] = [V] ? what is the difference between the currents from the STR file and those from the OS file? My guess is the currents from OS file are obtained before applying certain expansion function such as RWG, and the currents from the STR file are after applying the expansion function.
Thank you in advance for answering my questions.

The values exported to the STR-file can be accessed using the str2ascii tool, located at http://www.feko.info/support/helpcenter/how-to/how-to-read-the-.mat-.lud-.rhs-files-and-.str-files
The values exported to the STR-file are the matrix solution coefficients - if RWG basis functions are used the values correspond to the currents on the triangles.
If you solve the CMA eigen equation using the matrix (which you exported above), you will calculate the eigen vector which in the case of RWG-basis functions then correspond to the eigen current.
