Hi,
I'm running a simulation of Temporal interference on a four-layer head model. There are two pairs of electrodes attached to the head model, one with a 1 KHz electrical wave and the other with a 1.04 KHz frequency. However, I'm encountering an issue with the placement of the electrodes on the scalp.
When observing the overall field, I noticed two regions within the simulation where there is no field, indicating a problem with the electrode placement. I've attached a picture of the observed field for reference.
Here's a summary of my project progress so far:
- Created four spheres representing the layers of the head model: brain, CSF, skull, and scalp.
- Subtracted the inner spheres from the outer ones to accurately represent the head's structure.
- Positioned four cylinders along the radial axis of the spheres to represent the electrode pairs. The cylinders are aligned with the radius of the spheres and intersect with two outer layers.
- Attempted to attach the electrodes to the scalp by subtracting the intersected layers from the cylinders. However, the attachment is not as expected.
- Started a new quasi-static EM LF simulation
- Configured the simulation setup, materials (for brain layers), boundary conditions (for electrodes), grade, and voxel settings for each pair of electrodes separately.
- Assigned a priority of 1 to brain layers and a priority of 2 to electrodes to prioritize brain tissues during simulation voxelization.
- Extracted the overall field for both electrode pairs and selected them to observe the maximum modulation field.
I would appreciate any insights or ideas on why this issue is occurring.
Thank you!
