Error post-processing Meep Rod Dipole example
I carefully ran the Rod Dipole example:
1 – Produce Meep input files only. 2 – Dry-run the current configuration 3 – Fully simulate the current configuration
without any changes or obvious problems. In the relevant session directory (371174L), I had a subdirectory of the name (xxx) I gave my project, and in that directory were three files:
When I closed that session and tried (session 371221):
4 – Load and post-process a completed simulation
I noticed the system had created a directory “data/sessions/371174L-expired” with all the files (I guess) copied from the “data/sessions/371174L” directory. It then started processing some things, presumably so I could view the fields, according to the new near-a and far-field settings I saw and left unchanged in the “7 Post-Processing” stage.
A bunch of stuff scrolled by and when it finished, the results list was:
* Structural Profile: Dielectric Constant * Material Model: Au_optical – 0.5 to 6.2 eV * Middleware Error Log * Middleware Output Log * Critical Error
In the stuff, were lines including:
Using directory “/home/nanohub/robinwhittle/data/sessions/371174L-expired” as the toolkit output.
The Middware Error Log included:
(I can’t cut and paste from the Java window, this is manually transcribed, and I couldn’t find a file with this in it.)
[Errno 2] No such file or directory: ‘/home/nanohub/robinwhittle/data/sessions/371174L/SaveFiles/Rod Dipole no changes.sim’
Sure enough, there is no such file there – but there is on in the same location in the “expired” directory.
I copied the file from the “expired” location to the “…371174L/SaveFiles/” directory and tried again, closing the 371221 session and starting a new one 371231. This produced even more errors, (again I don’t know where this Middleware Error Log file is in the system, but it appears the software found the file ‘/home/nanohub/robinwhittle/data/sessions/371174L/SaveFiles/Rod Dipole no changes.sim’ inaccessible. I checked via WebDAV and the Storage Manager – and the file was still there, apparently intact.
I am looking forward to using Meep!
