MOM matrix

Recommended Posts

Hi all,

for the following matrix equation:

I know how to extract the impedance matrix using the .mat file. However, I need to know how to extract the right-hand side of the MOM matrix i.e. VE and VH. [the external source information]

Thanks.

Hello Mohamed Hamdalla,

 

FEKO has an option to export a .rhs file (Right Hand Side) that represents the source information. Unfortunately I don't have any experience with reading that file, but it is listed in the documentation, but it looks like it simply shows the code for reading the file in Fortran. I think you can read it in any language that reads in the values in the same format, but I have never tried to do this myself.

This feature is activated by creating an environment variable (FEKO_WRITE_RHS).

FEKO_WRITE_RHS
If this environment variable is set (value arbitrary), FEKO writes the right side of the set of linear equations to a .rhs file. This is only useful for test purposes, such as when one wants to analyse this vector with another program.
