      I am trying to simulate a circuit, but I have problem and the simulation does not finish.

      The error says:
      “CIDF Schedule: error occured while calculating, component Erbium Doped MM Fiber
      Error in Erbium Doped MM Fiber: Parameterized signal at input port.
      Calculation failed!”

      Help me, please. What can I do in this case?

      Hi Juan,
      I have created a simple project (attached) for you. It is running and you can see the output spectra as expected.
      Hope you can use it as a start point to move forward with your project.

      thanks
      Mohamed

      sorry I forgot to attach the project.
      here you go

      Thank you very much for your help Mohamed, but I have another problem, I don’t know why the program doesn’t want to open the file you send me. When I try to open it, there is a message “Failed to load document from storage”. Would you mind sending me the document by mail?

      No problem.
      which version of OptiSystem you are using?
      I built it on Optisystem15.
      so you can open it for the same or newer version.
      just let me know to try to find a solution for you.

      thanks,
      Mohamed

      It is the same, I am using the 30-day evaluation version. I installed the application the last Thursday.

      I tried again, but it was impossible. Thank you very much for your aid. Can you send me a picture from the schematic. I am practicing some circuits trying to fix the problem with the general circuit.

    • #49874

      here is the schematic and the output results.

      good luck

      let me know
      thanks

      I have tried some ways, but I don’t know if the problem is with my computer. I don’t know why this error. I just practiced the diagram from the application of this website, and the problem appears.

    • #49881

      did you try the combiner with CW laser?

      there is a built-in example similar to this project titled “MM EDFA ExampleAllModesEquallyExcited.osd”
      try to open it !!

    • #49894

      Hi Juan,
      There is an example titled “MM EDFA ExampleAllEquallyExcited.osd”
      Have you tried it? it similar to what you need. then you can delete the CW Laser and the pump coupler.
      let me know.
      good luck

      thanks
      Mohamed
