[Meep-discuss] meep-mpi on mac

Dear Steven, I have installed meep-mpi on mac using fink. It works fine with single core. But when I try to run it parallel, it shows error message. I couldn't understand the problem. The error message is given below. Please help me. Thanking you in advance, Ajith Administrators-Mac-Pro:1 admin$

Re: [Meep-discuss] meep-mpi on mac

My guess is that mpirun tries to setup the connection to all nodes (every cpu core is counted as a single node) and fails. OpenMPI may use different methods for connection to nodes - ssh, rsh, shared memory etc. In your case it looks like trying rsh - this is AFAIK default OpenMPI behaviour. Read O

[Meep-discuss] output from two h5 files on single color scale

Hello, Is it possible to use h5topng to place slices from two separate .h5 files on a consistent color scale or to have the values of the .h5 files normalized to the same value? Thanks. -- Carlos Octavio Aspetti Ph.D Candidate University of Pennsylvania Department of Materials Science and Engine

[Meep-discuss] Negative flux values for a transmission spectrum due to improper normalization perhaps

Dear Dr.Steven and meep users, I am trying to find the transmission spectrum of a straight waveguide using a gaussian source. I am getting negative values for some frequenciesand for some, the transmission shoots up, way more than 1.The intensity is

Re: [Meep-discuss] Negative flux values for a transmission spectrum due to improper normalization perhaps

Sanchit, The problem is that your incident flux is being bombarded by reflections coming from the structure. The proper way to normalize is to run the simulation twice, once without the structure in question, and once with the structure in question. Since in this case the entire waveguide is wha
