Hi all,

I have built the circuit in the link: https://www.circuitlab.com/circuit/95x5wt2dtk86/mains-filter/

I can't do a frequency domain simulation. I get the following message: Running Bode solver Error building graph. Aborting non-infinite value.

What do I do wrong?

Thanks, Saul.

Hi Saul, sorry for the cryptic error message!

Currently you have L1, C1, and C2 with values specified as 1U, 33N, 470N. If you simply remove the capitalization from the parameter, and make them lowercase 1u, 33n, 470n, I think you'll be OK.

(Also, I see in your Frequency Domain simulation you have a Sweep Parameter set up for V1.Frequency. You should turn this off! Frequency domain simulation mode already sweeps over frequency of the specified input source, and doing this redundantly simply increases your computation time without changing any results.)
