I am running multiport EM simulation on anatomical models. In some cases i observe diverging simulations:
- I observe that the E field is very large in few voxels which coincide with the part of the skin where the geometry is more complex.
- Sometimes it may happen to be close to the bounding box, but not always.
- I am using the default grid which comes with the imported model, updated for the frequency of simulation
- In some cases I overcome this problem by changing the simulation boundary or extending a water bolus more (which is specific to my application)
Do you think that the cause for this might be something else other than insufficiently refined grid ?
