How to find a model that work in simulation?

Hi. This is a follow-up to a previous case (https://easyeda.com/forum/topic/LM358N_simulation_shows_no_gain-moUcuoGYg). Now I'm trying to use LM2902N and no library model produces an expected output. No gain again. I suppose that I should use another quad-pack opamp model, but how to know which one simulates?

Please see: https://easyeda.com/forum/topic/How_to_find_simulatable_parts_in_EasyEDA-1YgasK2kC There is no dedicated LM2902 model available for the LM2902 but the LM2902 is basically the same as the LM324: http://www.ti.com/lit/ds/symlink/lm2902-n.pdf The LM324 is in the library so you can place a `5pin_Operational_Amplifier` Spice symbol from `System Components > Spice Simulation > Spice Miscellaneous` into your schematic and then edit the name from UA741 to LM324.
