If you are excited about the EMDrive and wants to contribute to its research, but don't know how, this is a step-by-step guide that if performed correctly by anyone out there interested in helping would provide valuable information for the scientists to study and better understand the EMDrive behavior.1. Install MEEP http://ab-initio.mit.edu/wiki/index.php/Meep (preferably from your package manager)2. Download https://forum.nasaspaceflight.com/index.php?action=dlattach;topic=37642.0;attach=1042821 and rename it to NSF-1701.ctl3. meep NSF-1701.ctl4. Eventually, MEEP will output nine .h5 files. It may take a long time depending on your computer. Patience is a virtue.5. h5totxt -t 13 -0 -y -0 ex.h5 > zCopper-exy.csv6. Open your zCopper-exy.csv on a spread sheet and aero's zCopper-exy.csv on another. Open a third spread sheet that is one spread sheet minus the other, entry by entry. Check that highest entry (in absolute value). If it's negligible you are good to go. If it's a value too big, greater than 10^-6, your MEEP installation isn't in sync with ours, so it's no use.7. Now you are good to go. Make a new directory to start the tests. Copy NSF-1701.ctl there.8. Open NSF-1701.ctl in a text editor and change avalue. For example, (set! high 10.2) means the model is 10.2 inches high. Change the 10.2 to another value and save NSF-1701.ctl with thischange. This is called sensitivity analysis. One value at a time. (set! high 10.2) was just an example, change any value of interest9. meep NSF-1701.ctl10. h5totxt -t 13 -0 -y -0 ex.h5 > zCopper-exy.csv11. Compare your new zCopper-exy.csv with your old one. See if there was any relevant change (do the spreadsheet comparison again). If there was no considerable change in values, it means. This is an important information for scientists, so let us know. Otherwise, if there was a significant change, let us know if it was positive or negative and its intensity. If you don't know how, just upload the .h5 files somewhere and we will analyze it.
