 === Define Boundary Conditions
 
-Two boundary conditions can be selected independently among
-latexmath:[x], latexmath:[y] namely: `OPEN` and for latexmath:[z]
-`OPEN` & `PERIODIC`. In the case you select for latexmath:[z] periodic
-you are about to model a DC-beam.
+There is one boundary condition supported for the FFT solver namely: `OPEN` in 
+all spatial dimensions.
