Computer that creates actual voltage

[fredreload]

I want to simulate like a circuit inside computer, 2D or 3D, but at the resistor place I want an actual voltage to come out KAPAW, so I can have the image of a simulated current and wire inside the computer, pretty much I'd like to simulate voltage at any spot I want inside a 3D graphical space (multiple places) inside a computer. Any idea how I can do that?

You need a circuit simulator. SPICE is the best known (and widely used in industry).

And if you want it to generate an actual voltage, then you can use a value from the simulator to drive an D to A converter.

Right well, my idea about digital immortality is failing because it requires an actual voltage. So, we might have to go hardware again = =, 3D printing, and brain plasticity remains a problem, sucks

It is not clear what your problem is. Why is a simulation not suitable? You can either get the computer to display the voltages at various nodes (graphically, if you wish) or use the values to generate a corresponding voltage output. Are neither of those suitable for your purposes?

 

And what are you planning on 3D printing? That is a bit of a leap from simulation.

Brain plasticity would emerge from your simulation, if it was accurate.
