ERROR 174: Frequency is too small or has not been defined

Hi,

I get this error 

 ERROR 174: Frequency is too small or has not been defined

while trying to simulate an antenna using Edit Feko, Hope you could help!
Note: the simulation using CadFeko run without any problems, and I didn't change the frequency range when I opened the Edit Feko.

 

Thank you!

Hi ALM

 

From your description I understanding the the FEKO model was able to run through CADFEKO and that you then manually edited the PRE file through EDITFEKO.

 

In that case it is possible that you added a solution 'card' in the PRE file above the FR card that defines the solution frequency. If such a card triggers a FEKO solution before the frequency is set, we would expect the error mentioned above.

 

As such, I would recommend that you check the order of the added cards to ensure that a solution is only requested after the FR card.
