CST transient solver = FDTD?
Hi Aaron,
As far as I know the original FIT in time domain and FDTD are pretty much similar.
The advantage of FIT compared to FDTD is, that FIT used some global matrixes which describe the system. This makes it easier to include some additional feature like the ?PBA? and the ?thin sheet technique? in the code.
If you switch off all these additional features in CST you would end up with a ?normal? (but very user-friendly ) FDTD code.
Same memory requirement, same time step criteria ?..
Best regards,
F.
good explaination
