When working with the mesh module there is a known issue that may occur depending on the users workflow. This being when a user runs the initial mesh studies, and then goes back to their sites and makes changes to either the antenna pattern files, edits the transmit/receive parameters, or just makes general changes. If this is the case the user should navigate to Studies>Study Preferences and press the “reset all working files button”. Then go back into MegaMesh and clear the cache files located under the setup and sort menu. And lastly, re-run the entire mesh study process after clearing the cache files in order to see the changes made to the site.
This issue occurs because after running your mesh studies, the program builds a cache file for those studies. These cache files get re-used when running the mesh studies again. If you make changes to your sites, which are outside of the MegaMesh menu, those site changes dont get taken into effect, as a result of the cache files that were built from the previous mesh study.
You must clear the cache files and rebuild them by running a fresh mesh study.
If propagation model changes or edits of any kind are made, you should go through the same process of clearing the caches files and running a fresh mesh study in order to see the changes taken into the effect. The mesh module works by reading cache files from previous runs of the study in order to save time. If changes are made to the propagation model or to a site, you will need to clear and rebuild the cache files before you see accurate results reflected from your changes.
