TAGGED: command-line, FDE
May 30, 2022 at 2:33 pmmatteoSubscriberHi I've been following https://support.lumerical.com/hc/en-us/articles/360024812334-Running-simulations-using-the-Windows-command-prompt, and I want to run a FDE simulation using a .lms file containing the waveguide to model, and a .lsf script that modifies the wavelength of the simulations and calls "findmodes" to run the simulation.
I haven't been able to find online a way to do it.
Calling "mode-solution geometry.lms" correctly opens the GUI
Calling "fde-engine.exe geometry.lms" loads the file and perform meshing, but then it stops (obviously)
Calling "fde-engine.exe geometry.lms -run script.lsf" or "fde-engine.exe -run script.lsf geometry.lms" yields an error saying "The file is not a *.lms simulation file. The simulation cannot proceed. Error: parallel error, at least one process could not read the designated file. Process number: 0 had this error"
May 31, 2022 at 5:05 pmLito YapAnsys EmployeeScripting is part of the CAD/GUI environment and run with the CAD/GUI executable as shown here.
Example: ..\mode-solutions.exe -run scriptfile.lsf simulationfile.lms
Have you tried running the script in the MODE CAD/GUI?

I have a question regarding your documentation then... What does fde-engine do then, actually? Because it looks like it just calculates the mesh of the .lms file that is passed to it.

FDE engine is to let you calculate the mode property and do the analysis, such as frequency sweep and overlap calculation.
