  1. 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...


  2. 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.


  3. Clarify Mueller Matrix returned by DDSCAT

    Open | Responses: 1

    I'm making Mueller Matrix measurements of silver nanocubes as part of my dissertation research at Air Force Institute of Technology. I'm trying to compare measurement to results...


  4. could’nt compute E-Field

    Closed | Responses: 2

    Dear AbderRehman,

    I couldnt obtain E-field since last software update. I tried to re-run an old simulation but this time extinction efficiency factor results are different (lower)...


  5. dimension of the object

    Closed | Responses: 1


    I have been able to obtain exact dimension of the object by utilizing the scale in Blender. e.g. i draw a cylinder with length of 25 blender units and diameter 7.5 blender units....


  6. Error while compiling DDACONVERT code.

    Closed | Responses: 2

    I want to locally compile the DDACONVERT tool on my Linux Ubuntu system. After downloading the code I tried to rum the make command in SRC directory via terminal and the following error was...


  7. 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...


  8. 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...


  9. how to excite transverse and longitudinal mode for a nanorod in a single simulation?

    Closed | Responses: 1


    Two basic question

    1. how to excite transverse and longitudinal mode for a nanorod in a single simulation?

    2. what will happen if I will select the...


  10. How to modify the code to run with only gfortran and without openmpi installed in the system?

    Closed | Responses: 1


    I am a neophyte in linux and don't have iFort and openmpi installed in my Scientific Linux. If you could help me to run it without those it will be very helpful.


  11. is it possible to obtain data from aborted simulation session

    Closed | Responses: 1


    i am interesting to know if it possible to obtain data (e.g. qtable) from aborted simulation session? I shall be thankful to you

    kind regards



  12. 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...


  13. length of the object

    Closed | Responses: 1


    I know you have provided detailed guidance regarding this in manual but somehow i am missing something. there are few questions regarding exact size of the object



  14. newer version of DDSCAT

    Closed | Responses: 2

    Dear All,

    Does anybody notice these differences in newer version

    1. Number of dipoles

    in my previous simulation, a Blender cylindrical object with 3.5 diameter and...

    I am using custom shape (cylinder) with diameter 7.5 nm and 25 nm length. i am interesting to excite longitudinal plasmons but unfortunately i am not success, i have changed the...


  17. some wavelengths are missing the spectrum

    Closed | Responses: 1


    I used the option "Remote parallel DDSCAT with wavelength splitting" for 4000 minutes (2.7 days) over the weekend and got the results back after almost 1.5 days. i am...


  18. 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...
