    Hello,

    Sorry I am facing an issue with moving antennas to different locations based on the steps above. I used three points on the skin and calculated the transformation between static and posed states. I used this transformation to transform the antenna position to the new position (using RigidTransform and ApplyTransform functions).

    However I get errors that the antenna source edge is within a solid. I have changed priorities during voxelling providing antennas higher priority but the errors still exist. What can I do? I would like to move antennas in a similar fashion to how soft tissues deform.

    Thanks

    Hi,

    Thank you. I tried it but would like to plot the fields on a grid between antennas (as shown in red in the image). It is easy when the model is static but when posed, I am not able to get a grid at an angle.

    Thanks

    Then you can keep the substrate as it is and translate the edge source (polyline) along the microstrip line until it also touches the ground plane (keeping it always axis-aligned).

    @MSJ the modify button is probably hidden on the top right, if you click the triangle where you see the three dots (...).

    Yes, you cannot directly stretch a group. However, you can select multiple (non-group) entities and stretch them.
    The easiest is to press "Ctrl+A" (Select All), which will select all visible entities (excluding the groups), and then stretch those.

    You can also use the Python API.

    import XCoreMath import XCoreModeling Vec3 = XCoreModeling.Vec3 scaling0 = XCoreMath.Scaling(Vec3(2.0)) scaling1 = XCoreMath.Scaling(Vec3(1.2, 0.9, 2.0)) scaling2 = XCoreMath.Scaling(Vec3(1.2, 0.9, 2.0), origin=Vec3(120, 10, 34)) entities = XCoreModeling.GetActiveModel().SelectedEntities for e in entities: e.ApplyTransform(scaling0)

    the different scalings are

    uniform scaling non-uniform scaling non-uniform scaling wrt to the (non-zero) origin=(120, 10, 34)

    Hi,

    How do you ensure they are in xy,yz or xz plane. Visually they are but I still face the error?

    Hi,

    I decreased the max step of the dielectric material in the coaxial cable, but still got the same warning. I have two questions:

    Is there are formula which can be used to determine the cross-section? How does the warning affect the result?

    Thanks

    Hi,

    I would like to power the two waveports with an input which is 180 degree phase apart between each other. The antennas are constructed in a differential manner to increase penetration. I am not sure how to provide the power input to the waveport guide

    Thanks

    Hi @bryn , thanks for looking into this. I can reproduce what you write. However, in my case it is a little different because I do press Enter and still it would not update. Unfortunately, I do not know how to reproduce this behaviour in a fresh project. I will hope that the solution to your bug will also fix the bug that I encounter, though.
    Thanks!

    Hi Vignesh,

    Yes, "Surface Projection" tool should help you to place the antenna on a surface of a human body model.

    Hi Tomasz,

    I don't think the access violation error has anything to do with "protected models". I think this is a bug that should be reported to the support.

    What version of Sim4Life are you using?

    did you cut the "posable" Jeduk, or did you first "Clone As Static" did you cut using the Python API, or in the GUI? if you save the model as .smash or export as .sab/.sat file, is a file written? Can you load it? what other types of entities are in the model? what happens if you copy the model entities and paste them in a different instance of Sim4Life?
