help me to speed this tutorial

in this tutorial when i changed the length of SMF from 50 km to 1 km it take more more time to simulate it , i can’t know why although the distance was decreased it take very long time please any one help me
note that i am use optiwave version 13

Hi Ahmed;
I run the project.It take 13 Seconds and completed successfully without error.

[ahmedbasuonyParticipant]

if you modify the length of smf fiber to 1 km not 50 km it will take more time

[Abdallah IsmailParticipant]

I relaced all 50km SSMf to 1km and changed EDFA gains to 0.2dB ten it take 6 seconds.
SMF take long in time in case of nonlinearity calculation because it increase the no. of steps if the power is large.

[ahmedbasuonyParticipant]

thank you very much but why you put 0.2 db for gain and how you calculate it ???

[Abdallah IsmailParticipant]

attenuation = 0.2dB/km and the length = 1 km
so gain = 0.2dB/km * 1km = 0.2 dB
