PLEASE NOTE: This is what i did to fix the problem. Thanks to the people that help me.
NEED HELP.  This APP has a little problem in that the DC supply can not be shorted together.
But the circuit I'm working on has two batteries and a switch to select one or both.
Just need a way that works just like two batteries so i can short out the two positive sides withe the switch.
I have a circuit using two op-amps but i had to put a diode on each pos lead before the switch.
All i would like to know is a way to make the DC supplies to work like a batteries. Eg batteries have a high resistance to them.

Hi! Add in series with the voltage source resistance of a few milliohms.

All you need is the smallest resistor available, this simulates the wiring resistance. http://everycircuit.com/circuit/4829969657364480

@BillyT ... Just be sure that both batteries there read as 12v .... make one of them 11.9v and view the current.

@2ctiby yes this is a problem, in reality the bigger battery would pull the other battery up or down to balance the voltage load.

Thank you all for the input.

I didn't understand how you solved this problem. I have the same problem. I can't switch two baterrys parallel because of short current flow. Please can someone explain me how to get in this program? None of Yt videos contains the solvation of this problem and I didn't find a description in "every circuit" about voltage sources installation. I don't know where to start. I bought already a licence and I am about to give up this program

See this link of BillyT and you can even lower the resistance to the lowest value available. http://everycircuit.com/circuit/4829969657364480
