SBS fails at input power above approx. 35dBm

Hello, I am simulating SBS effects in fibers (nonlinear and bi-directional) and would like to simulate SBS as a function of input power to the fiber. The model seems to fail at input powers above roughly 35dBm. Increasing the maximum power reference value does not seem to work. The referenced paper for SBS does not suggest a high power limit.

Are there any suggestions on how to simulate SBS for higher laser power?

      Dear Martin,
      I am not sure what the settings are of the components you are using in your project. I’ve created a project with bidirectional fiber and used 40dBm into the fiber. The calculation is taking long time. However, I would email you the project and the results once it is done. Please send me your contacts at ahmad.atieh@optiwave.com.
      Regards,
      Ahmad
