Simulation settings
The following table describes the Simulation settings available in the ATP Settings dialog box:
Option Description
delta T Time step of simulation in seconds.
Tmax End time of simulation in seconds.
Xopt Inductances in [mH] if zero; otherwise, inductances in [Ohm] with Xopt as frequency.
Copt Capacitances in [micro-Farad] if zero; otherwise, capacitances in [micro-mho] with Copt as frequency.
Freq System frequency in Hz.
Power Frequency
Checking this button enables the system frequency to be typed in and written to the SYSTEM FREQUENCY request card in the ATP file. Power frequency specification is required for Harmonic Frequency Scan simulations.
Simulation type. Select between
Time domain
Frequency Scan
Harmonic Frequency Scan
If Frequency Scan is selected the FREQUENCY SCAN option of ATP is enabled.
min: Starting frequency for the frequency scan
max: Ending frequency for the frequency scan
df: Frequency increment. Leave 0 in logarithmic scan
NPD: Number of frequencies per decades in logarithmic scan.
If Frequency Scan or Harmonic is selected the user can select which component of the solution to print out.
Magnitude only: Default request
Magnitude & Angle: POLAR OUTPUT VARIABLES
Magnitude & Angle & Real/Imag: BOTH POLAR AND RECTANGULAR
Real/Imag: RECTANGULAR OUTPUT VARIABLES
Other combinations are illegal and are prevented by button logic.
