I believe the oblique-source.py example requires Meep 1.9 or later. You can create an environment for parallel pymeep 1.9 like so (note that the pymeep packages are now hosted on the conda-forge channel instead of chogan):
$ conda create -n mp1.9 -c conda-forge pymeep=*=mpi_mpich_* $ conda activate mp1.9 Chris On Wed, May 22, 2019 at 7:23 AM ei ru <37zi...@gmail.com> wrote: > Dear meep Users, > > When I run the example code of tutorial ( > https://github.com/NanoComp/meep/blob/master/python/examples/oblique-source.py > ) > , > I get the error saying nvalid direction in add_eigenmode_source. > The log is below. > I currently use pymeep-parallel of version 1.7.0 which is build from > py36_nomklh39e3cac_1 [nomkl] chogan. > If you have any idea how to fix this, please let me know. > Thank you. > > ###################################### > Using MPI version 3.1, 1 processes > ----------- > Initializing structure... > Working in 2D dimensions. > Computational cell is 14 x 14 x 0 with resolution 50 > block, center = (0,0,0) > size (1e+20,1,1e+20) > axes (0.939693,0.34202,0), (-0.34202,0.939693,0), (0,0,1) > dielectric constant epsilon diagonal = (12,12,12) > time for set_epsilon = 2.01864 s > ----------- > meep: invalid direction in add_eigenmode_source > application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0 > [unset]: write_line error; fd=-1 buf=:cmd=abort exitcode=1 > : > system msg for write_line failure : Bad file descripto > ######################################## > _______________________________________________ > meep-discuss mailing list > meep-discuss@ab-initio.mit.edu > http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
