I am trying to perform Monte Carlo simulation and worst-case simulation on a filter circuit. The tolerances of resistors and capacitors can be modified. But can the tolerances of core components such as amplifiers or other power chips also be set? If so, how can I set them?

Using the parameter scan function, can two variables be scanned at the same time? For example, I need the values of capacitor and resistor to change within a certain range. I observed the interface of the simulation configuration file and it seems that only one parameter can be set for scanning?

When performing Monte Carlo simulation to modify the tolerances of capacitors and resistors, I modified them manually. For example: manually modify from 10% to 5%, and then run the simulation to see if the results meet the requirements. Is there a way to automatically change the tolerance value from 1%, 5%, and 10%, and after the run is completed, I can observe the output simulation results in these situations at once. Thank you very much!

I'm simulating a low pass filter circuit. Two DC power supplies are used to share power for the amplifier, but the two DC power supplies do not output voltage after setting the values，why?

3. Results and Discussions 3.1. Room DescriptionThe size of the room is L = 3 m, W = 4 m, H = 3 m. For the south-facing room located in Shanghai, the glazing is double-glass pane windows with low-E coating. The solar transmittance of the glazing is 0.6, the absorptance is 0.33, and the reflectance is 0.07. The internal surfaces of the room are assigned a solar absorptance of 0.6. The distribution of solar energy at summer solstice is calculated using two methods.

An ultrahigh sensitive trace gas sensing system was presented with dual cantilever-based differential photoacoustic detection. By combining the double enhancement of multipass absorption and optical differential detection, the gas detection sensitivity was significantly improved. The dual-channel synchronous photoacoustic detection was realized by fiber-optic Fabry–Perot interference spectrum multiplexing.
