Despite increasing the k-vector value, I encountered two issues: either the simulation time became as lengthy as FDTD simulation, or the simulation stopped abruptly. Additionally, I couldn't locate the "use tangent vector field" option when opening the simulation in Linux. Any insights on how to address these challenges would be greatly appreciated.
