Reading docs about How do I simulate my schematic in Flux? Steps to run DC operating point or transient analysis, add probes to nets and pins, view voltage/current plots, and adjust source parameters and sweep settings..

Here’s the most relevant entry I found related to your request. Quoting the Flux docs:

"If you want to learn how to use the simulator, take a look at this tutorial.

Let's discuss how simulation models run inside Flux.

First of all, Flux comes with a built-in, state of the art programmable electronics simulator. Electronic circuit simulation software has been around since at least the mid 70s in form of SPICE and there is an ocean of open-source successors available today. Yet electronic circuit simulation hasn't found ubiquitous application because it's challenging to build the simulation models that define the behavior of each electrical component (e.g. a resistor)."

Would you like me to walk you through running a quick DC or transient simulation on this project and where to place probes to see voltages/currents?

Reading docs about How do I run a DC operating point or transient analysis on my schematic? Include steps to open the simulator, configure sources, place probes, choose analysis type (DC operating point vs transient), run, and view plots. Also include how to sweep a parameter or adjust simulation time/step..

Reading docs about DC operating point analysis: how to run it in Flux on a schematic. Also: how to run transient analysis, set time step and duration, and view node voltages/currents..

Here’s the most relevant entry I found related to your topic:

“The simulator tool works with standard SPICE netlist syntax. Here's a simple example:

Simple RC circuit V1 1 0 DC 1V R1 1 2 1k C1 2 0 1u .tran 0.1u 10u .print tran v(2) .end

Important notes:

Always include a .print directive to specify which node voltages or branch currents to output
End the netlist with .end
Include appropriate analysis commands (e.g., .tran, .ac, .dc)” Source

Run DC operating point

Run transient analysis

Sweep a parameter

Adjust step size
