  2. Why do I get only one point after running the simulation

    Open | Responses: 1

    I am trying to simulate nanorods for different aspect ratios, but after running the simulation, the graph shows only one point instead of a curve after setting the spectral window 400 - 700 nm....

  4. Nearfield not working?

    Closed | Responses: 1

    I tried to do nearfield calculation, but the initialization always sets the parameter to 0, even if choosen in the menue.

    Is there any explanation for this?

    Can I generate...

    Hello,

    I want to run a Nearfield generating simulation using DDSCAT, but i could not get the final results for limited storage. What should i do? Thanks.

    Reason: 
    "The third parameter for Cylinder must have a value of 1 or 2 or 3." 

    I've done this test multiple times with the three different...

    Hello!

    I tried a simulation of a gold nanorod with size 41.1nm X 14.3nm (SHPAR1=26.8, SHPAR=14.3) with shape file: Cylinder with End-Caps. 

    But it crushed every time at...

  9. axes label and the zero point

    Closed | Responses: 2

    It would be helpful to position the axes labels at the end of the each axis. The current display is not clear.

    Also the zero point is printed as a small number in scientific notation...

  10. output file to simulate in matlab

    Closed | Responses: 1

    Do you guys have a matlab code that will allow me to use the target output file to simulate the 3D field so that i can mess with the colors of the intensity?

  11. Results log zoom in/out issue

    Closed | Responses: 1

    I noticed that when i was zooming in and out of the electric field (3d field) results log that the whole page scrolls up and down. Could you fix this little issue please.

  12. How can I change the Intensity scale?

    Closed | Responses: 3

    I would like to be able to see small changes in the intensity display. The electric field displays in just one color right now because there is very little variation in the intensity. I would...

  13. Stop running and no output

    Closed | Responses: 2

    When I use “Remote Parellel DDSCAT with Wavelength“option to run simulation, program will stop running simulate after 3-5 hours and create no output. Why could this happen?

  14. Can the simulation save data for future use?

    Closed | Responses: 1

    After running various simulations I wondered if the program can save the data obtained which then can be retrieved at a different time. For example if I were to publish a paper using your...

  17. can the Storage limit be increased?

    Closed | Responses: 3

    I am currently running some simulations and I would like to know if the storage for the ddscat tool be increased to 5 GB. This would allow more detailed simulations to be obtained.
