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)

Answering my own question:

In the Modelling tab (not simulation), each imported label/voxel type can be assigned a material in the Controller window.

Auto Assign seems to work decently well if the materials in the file are well named.

Probably should be done before dragging the model into the Simulation.

@montanaro Thank you! The acoustic reflection simulation is now behaving and giving results which map to what you'd expect.

Thank you so much for helping! Jean

Like all entities in the Analysis pipeline, the Matlab exporter has an Update method to execute.

to find more information on a specific class you can

export the pipeline from the GUI as a python script use the help() function to get more information on a specific class, e.g. import s4l_v1 as s4l help(s4l.analysis.exporters.MatlabExporter)

Dear Jasper,

At the moment, it is not possible but your request will be added to the feature request list for future releases. Thanks.

Dear Shreya,
I assume you meant simulated 1g and 10g SAR values. If you are referring to dipole antenna tutorial, it is not possible to extract SAR values since the simulation project does not contain any lossy object - it is just a dipole antenna in free-space. Please check "SAR in a Flat Phantom" tutorial and section 3.1.4 of Sim4Life tutorial document for details related to SAR simulation and extractions.

Dear AntoninoMC,

Thank you for your comprehensive solution!!!
Following your advice, I assigned distinct priorities to each tissue, and there is no more need for boolean operations (subtraction). This approach proved to be completely successful.

Hi @tcs,
EM LF Electro QS simulations are electric simulations executed in the LF approximation, where the electric and the magnetic fields are decoupled. Therefore, the electric simulations do not produce any magnetic-related quantity (H and A-field).

In order to simulate problems involving magnetic fields, one of the EM LF Magneto solvers need instead to be used).

If your problem involves radiofrequency EM fields instead (e.g. above 1MHz), the EM LF solvers may be inadequate and you should use the FDTD solvers.

All the best!

@Hüfer yes, you can access all the simulation results as well as the parameters of you EM-neuronal simulations using the Python interface. For example, you can access titration data, or the transmembrane voltage profiles stored on a point or line sensor data, etc. or you can dynamically change the stimulation pulse shape parameters (phase duration, amplitude, etc.).

Sim4Life provides you already with some Python tutorials. There are at least 3 tutorials provided that show how to use Python to setup a T-Neuron simulation, how to run it and how to access the simulation results. Please have a look at these tutorials to learn Sim4Life programming (if you are a Python expert, learning will take you a day!).

To access these tutorials, open the 'Scripter' panel in Sim4Life, and load one of the scripts in the folder opened when selecting "Open Example Script" clicking on the open folder button.

Hi,

Currently, there is no tool in Sim4Life allowing you to extract the S-parameter in time domain. You might evaluate it via Python scripting (using already available time-domain data of voltage and current at ports or inverse Fourier Transform). Sim4Life team is informed to include this request in the development plan and will inform you in the future once it is implemented.

Hi,

Please contact Sim4Life team via s4l-support@zmt.swiss. Thanks.

Hi Micol,

Did you model the waveguide filling (where you placed the waveguide source) and set the material parameters of this object correctly in the simulation settings?

Hi, please send the file to s4l-support@zmt.swiss address. Thanks.
