Why the difference between Multisim simulation results and real world circuitry

Highlighted

Hi. I am developing some new circuitry in Multisim version 12.

The problem is after running numerous simulations, I believed that my model was finally complete.

I then moved to testing using a solderless breadboard only to realize the simulations were wrong.

Are there any others who have experienced this?

How did you resolve the issue?

Define "wrong". Slight differences? completely different?

Can you guarantee that you did not make any mistakes?

It's completely different.

I ordered the exact same components online that I used in the simulation and used the exact voltage to two decimal places.

The voltage, current, frequencies I measured from the solder-less breadboard were completely different from the simulation.

Should I proceed using the real world devices and ignore the Multi-sim simulation results?

Which is very disappointing.
