AcuTrace output data

Hi, experts.

When analyzing particles with different parameters using acutrace, is it possible to distinguish the particles by those parameters in the end file?
Or is it possible to distinguish between particles in .*seeds file 1 and particles in *.seeds file 2 on .end file, for example?

    It looks like it would only be distinguished by the Global Seed ID/Number - all in a single .end file.  If your seeds files specify the Seed IDs, that numbering should be preserved/consistent in the .end file.

    Thank you for your reply.

    In the analysis I did, I did not specify the seeds ID.
    Your comment is very helpful for me.

    Could you please tell me how to specify the seeds ID?

    The Seed IDs are specified in the PARTICLE_SEED commands:

    Thank you for the useful information.


    I read that seed_coordinates specifies the seed position and a list of seeds IDs.
    I would like to load the seed list from a CSV file into the model. In that case, should I create columns for seeds ID, x coordinate, y coordinate, and z coordinate in the CSV file?

    However, when I tried the above, HyperWorks CFD could not read these four columns.
    Could you please tell me how to specify the seeds IDs assuming that they will be read from a CSV file?

    Thank you.

    I believe a row would look like this

    ID,X_Coordinate,Y_Coordinate,Z_Coordinate

    no spaces, only comma-separated

    Best way to test the format is create a few seeds in the GUI manually, then save those seeds to a file.
