Using the functionality in the bread crumbs bar, the following services are added to it and brought into the following order:
image import: A file import service (picker) (*)
image segmentation: A python runner service with AI libraries
segmentation inspection and correction: An iSeg service (*)
nerve model creation: A python runner Smash service
electrode creation and placement: A S4L GUI service (*)
simulation setup and execution: A python runner Smash service
results visualization: Another S4L GUI service (*)
interactive exploration through jupyterlab smash (*)
A python script and neural network descriptor (to be provided to the team) are inserted into the python runner service (how? Preferably not through a picker, as they should be permanently stored in the pyhon runner service). They are to perform he task of presegmenting the image
Another python script is uploaded into the python runner Smash service (to be provided to the team). That script is to convert the image segmentation into a smash file with a nerve model, incl. neuro-functionalization.
Another python script is uploaded into the python runner Smash service (to be provided to the team). That script is to accept a smash file and to convert a meshed and neuro-functionalized nerve model adhering to some naming conventions for regions, boundary batches, and neurons into EM and neuro simulations, to execute them using the computational service execution API, and to perform some analysis of the results, before saving the resulting smash file again.
Using the corresponding dialog, a guided mode version is set up in which only the file picker, the iSeg, the two s4l gui services, and the jupyterlab are visible (marked with (*) above).
The study is saved and converted into a template
In the dashboard a study launched from that template, in guided mode
An image file is picked. Next
The result of the AI segmentation is inspected and corrected using iSeg. Next
An electrode is modeled and placed on the nerve geometry. An unstructured mesh is generated. Patches for the boundary conditions are defined. Next
Results are visualized, based on the available data (field sensor, titration sensor…).
The study with results is shared with all of z43
Bonus: instead of twice inserting complete S4L service, only the modeler version of it is inserted in the first instance and only the postpro/viewer in the second instance
todo: jupyterlab step
Modeling preparation with the structured solver
Import segmented image
Extract outlines
Convert outlines into surfaces
Extrude surfaces along a trajectory spline
Model electrodes using constructive geometry and place them
Modeling with the structured solver
Create an ohmic current dominated structured LF sim

Use the current density, the flux integration, and the normalization tool to normalize the simulation results to a 1mA total current
Model preparation for unstructured EM simulation:
Import segmented image
Create surface mesh on the labeled image
Extrude surface mesh outlines along a trajectory spline
