We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Muhammad,

In FDTD simulation, we calculate the electric field first and then the mode volume is calculated using the equation. Are you using an analysis group to calculate the mode volume? If yes, you will see that there is a DFT monitor within the group that calculate the eectric field distribution.
