Script Only Simulations in AKABAK-3

[oomptss]

I'm looking to do some simulations from script only from AKABAK-3. I get error during processing:

ERRORS ------------------------
All sources muted (provide LE-network or enable Fixed Driving)

Repro Steps:
- New Project
- BEM -> New Component -> Script
- Specify text file with the following:

>>>>

Def_Driver 'SimpleSpeaker'
Sd=150;
Re=8;
End

Def_Signal 'SimpleSignal'
Amp=1;
Freq=1000;
FixedDriving=Yes;
End

Network
Node=1
Driver='SimpleSpeaker', Node=1, Signal='SimpleSignal'
End
<<<<<

- Processing -> Calculate All

Any ideas how to accomplish running script only simulations?

Regards
