RLC at resonance (effect of Max Time Step setting)

Circuit Description

Voltage measured by probe PR1 should be zero as the circuit is at resonance, however the transient simulation shows a steady state amplitude of about 1.2V. I have done a single frequency AC analysis of the same circuit with Multisim 14.1 which shows an amplitude of 45.4uV (i.e. close to zero, as it should). Is this a bug with the transient analysis algorithm?

Hi Alberto. You need to adjust your maximum time step because you are operating at the resonant frequency. Try 1e-6.

Hi Shauna, excellent. Thank you!

I know this topic is a bit old, but could you explain why adjusting timestep is important at resonant frequency? I going through the same problem (with another simulator) and I don't understand why it's happening.
