  1. Nearfield not working?

    Closed | Responses: 0

    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...

  2. How can one normalize the E-Field intensity?

    Closed | Responses: 1

    More specifically, what is the initial Electric Field intensity (E0)2 of DDSCAT? 
    I want to create a normalized E-field intensity data map

  3. limiting storage

    Closed | Responses: 2


    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.

  4. I keep receiving an error after I run my simulations on a single cylinder.

    Closed | Responses: 1

    "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...

  5. Simulation error considering MXNX,MXNY,MXNZ

    Closed | Responses: 3


    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...

  6. 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...

  7. 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?

  8. 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.

  9. 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...

  10. 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?

  11. 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...

  12. How soon will the software be able to set the rotation of the object relative to the incident light?

    Open | Responses: 1

    I know that the option is hidden for now, “working on a gui based method to set the rotation of the object relative to the incident light.” I would like to know if it is possible to...

  13. Is there a way to change the polarization direction for the x axis to the y or z?

    Open | Responses: 2

    In the code I see ****define incident polarizations **** (0,0) (1,0) (0,0) = Polarization state e01 (k along x axis) Lets say I would want to observe the polarization of the object from a...

  14. 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.

  15. why does the 3D field electric field feature complie all previous simulations?

    Open | Responses: 2

    After doing a few simulations I noticed that in the 3D electric field feature seemed to keep previous simulations and I can not have it focus on one. I did unpress the ALL button but previous...

  16. can this tool be used to predict eutectic point of a molecule ?

  17. Limit of dimensions

    Closed | Responses: 3


    I’ve tried to complete a simulation on a Ag/Cu core-shell nanowire using concentric ellipsoid. It has failed 3 times now, even at 1000 iterations.
