    @bryn Is the 6.8 displayed on the color bar the actual maximum field strength value? I exported the values and found that the maximum is around 5.9 instead. 42fb974e-d830-42c2-8373-84c85ee63339-image.png

    @halder This is the max modulation value I extracted, and the vast majority of the values are NaN. However, when I checked the slice viewer, I didn't notice any issues. Are these NaN values treated as 0 in the slice viewer? I extracted this value to create a 3D dataset, so I'm a bit confused about how to handle these NaN values.aaf9e88d-cb7e-4fb4-b7db-530bfcbc1b79-image.png

    You can open a smash file using

    import s4l_v1 as s4l s4l.document.Open(smash_file_path)

    You can save it using

    s4l.document.Save(smash_file_path)

    You can find a simulation using (assuming you have unique simulation names

    sim = [sim for sim in s4l.document.AllSimulations if sim.Name == "the name of your simulation"][0]

    If you want to load different models (from .sab file or .smash), but don't need to load e.g. simulations (in .smash file), you can import the file

    entities = s4l.model.Import(file_path)

    if you need to reset the document or model because you are accumulating too many entities and memory use is getting too high, you can use e.g.

    # reset the model sl4.model.Clear() # or keep entities, but discard model history import XCoreModeling as xcm xcm.GetActiveModel().ClearHistory() # or reset entire document (reset model, simulations, analysis) s4l.document.New()

    I want to see the impact of different grid sizes on the simulation, so I cloned a pair of simulations and modified the maximum step size of the grid. However, I found that if I create a new pair of simulations using the same settings, the grid sizes, simulation durations, and results of the new simulations and the cloned simulations are all different. Why does this happen?

    Assuming a linear relation between voltage and pressure amplitude, you should be able to map the input voltage to the input pressure (I think its 1 MPa by default), and then use this as a scaling factor, but it's unclear to me what you mean with voltage at the focused area.

    What exactly do you mean by transducer sensitivity? You could run additional simulations where you shift the transducer or slightly change some parameters to get a sense of the sensitivity.

    Great! Goit it, thank you so much.
    One last question regarding where the simulation outputs are located and saved. The coordinates of the voxelized entities where can be found?

    Thank you so much for your time 🙂

    Hi @tayjiekai

    sim4life.lite is the student version of our online simulation platform sim4life.science and comes with certain limitations. As indicated by the error message, it does not support a number of neurons exceeding 10. If the limitations of sim4life.lite are too restrictive for your work, I suggest transitioning to the full Sim4Life web version at sim4life.science.

    Hi, you can get additional information by enabling the "Far Field" sensor and then choosing the "Radiation Report" evaluator (see for example the Phased Array Patch Antenna tutorial).
    It will not solve your problem, but might help you get a clearer picture. From what you describe, it's possible you have a very low mismatch efficiency (most of the energy is reflected).
    This could be addressed by improving the way you are modeling your source, or by just ignoring it if it is not important (i.e. if you are not actually simulating the real feed and are only interested in the antenna itself). You would do that by considering the Radiation Efficiency (ratio of Radiated Power to Accepted Power) instead.
