Hi,
typically a rectifier followed by a capacitor is used to supply a load with electrical energy.
This load usually specifies
* the allowed input voltage range ( maybe ripple, too)
* and the input current.
These are the target values to design your circuit.
Each load has other requirements, therefore we can´t recommend a universal solution.
--> for a detailed answer we need the specifications.
************
From simulation point of view there is no difference whether I put same value inductor on AC or DC side (equal rms current equal power dissipation).
Not true.
With an inductor on the input side you will reduce the input ripple current, but lower the (loaded) capacitor voltage.
With an inductor at the output side you may influence the voltage to the load in a way that the load will refuse to work. (depends on load). But you won´t decrease input ripple current significantely.
Please tell what "power dissipation" you talk about. (load, capacitor, inductor, rectifier...)

You talk about a simulation:
I assume you used a constant load current or constant load resitance... this often is not realistic.
--> Just to see the difference: use a varying load_current switching form 50mA to 100mA with 1kHz and measure the voltage across the load. Then you will see how much it differs when inductor is on the one or other side.

An inductor on the DC side sometimes is not useful to reduce the ripple current.
