We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

@Jordi Lopez Leyva,

From the command you provided,

/.../mpiexec -n 4 -host tue-login002 -env HOME /.../test /.../fdtd-engine-mpich2nem -t 1 /.../Nanobeam.fsp

Are you running the simulation remotely from a Linux machine to another Linux machine, 'tue-login002' ?

Are you able to log in to the Linux machine, 'tue-login002', and run it directly from there (not remotely)?

i.e. 
/cm/shared/apps/lumerical/2023-R1.1/mpich2/nemesis/bin/mpiexec -n 4 /cm/shared/apps/lumerical/2023-R1.1/bin/fdtd-engine-mpich2nem -t 1 /home/”MyPath”/Lumerical/test/Nanobeam.fsp

Otherwise, try the command below, without the '-env HOME' options for the MPI. Let me know if the issue persists even though the simulation ran successfully. 

/cm/shared/apps/lumerical/2023-R1.1/mpich2/nemesis/bin/mpiexec -n 4 -host tue-login002 /cm/shared/apps/lumerical/2023-R1.1/bin/fdtd-engine-mpich2nem -t 1 /home/”MyPath”/Lumerical/test/Nanobeam.fsp
