  Respected sir,
  Currently, we are using a workstation (RAM: 64GB, Memory: 1 TB, i7 Hp ), which is taking much more time (more than 60 hrs) for simulating a waveguide based device (using 3D FDTD and Var FDTD), less than 1 mm size, we are not able to increase the device size futher, and not getting the accurate results (e.g. coupling lenght) when we comparing with other Lumerical modules (FDE and EME ).We need to speed up the simulation time with accurate results for large size (more than 20mm) devices .We are requesting you to recommend the best hardware feature PC for our design and simulation such that we can able to fullfil our requirements.

  Hi Mijanur,
  Simulation speed performance depends the hardware (overall bandwidth of the system) and most of all the simulation/design and its components.
  Please see the following KB for more information and running Lumerical FDTD on some of the systems available on the cloud.
  - Hardware specifications guidelines – Ansys Optics
  - FDTD Performance Benchmarks – Ansys Optics
  Tip: For comparison, download and run the simulation (benchmark) files used in our tests on your machine.
  Let me know if you have any questions.
