Therefore, new modeling techniques are required to design and characterize these structures. Because the structures are inherently three-dimensional, they're not well suited to being designed and modeled in the traditional ways (which, much of the time, assumes relatively planar assemblies. My research involves assembling micro-electronics from pressfit parts.

FDTD PYTHON LICENSE
To further illustrate that the error is intermittent, (and also the fact that the license is correctly configured) please see the following traceback, where interaction with FDTD is fine, but MODE which is configured with the same floating license, opens the GUI but fails to establish a connection with lumapi on Linux CentOS7: > import lumapiįile "/opt/lumerical/v212/api/python/lumapi.py", line 1303, in _init_ mode = lumapi.MODE(), fdtd = lumapi.FDTD()) does not run correctly and the handle to the simulation is not assigned to to a variable in python and subsequent operations cannot be performed. The automation API also causes the GUI to open without prompting for a license, however the simulation handle initialization (i.e. When the license is correctly configured users may manually open the GUI without issue.
FDTD PYTHON SOFTWARE LICENSE
I can guarantee that the software license is correctly configured as if we set the license to the incorrect web address, the user is not able to load the GUI (as expected), and neither is the automation API.
FDTD PYTHON WINDOWS
We have observed this issue on both Linux (CentOS7) and Windows 10. It appears not to be license configuring issue from the user but a fault from the python API establishing a connection with the software. Several of our users have all independently verified that they have configured their licenses properly and have experienced the same problem with the API. The fault is intermittent, and periodically breaks for various Lumerical products. Unfortunately we are also experiencing this same problem and it is worth mentioning that we never had this problem in pre 2021 releases. Any help in debugging or fixing the issue is greatly appreciated. This issue just started appearing today, seemingly out of nowhere. So it looks like it is getting stuck when it is trying to open an FDTD instance.

The execution will just hang indefinitely.

I am running into an issue where I can run FDTD simulations via the GUI, but I cannot run them via the Python API.
