Are there any such programs for simulating electrical circuits?

Question

Electronics

Well, like programming, but only in electronics.
Type we set the power source, resistors, diode, transistors, capacitors ....
We start the current and you can see how the diode blinks. or if the crooked hand is not blinking) You can select the parameters of the transistor, the blinking frequency .... there is something like Multisim Is
there something else?
