Hi @tmedani
For windows, I have tried what you suggested(change index 0 to 1 in the 5th dimension of elem array). After I get the new mesh(isomesh), i tried to compute headmodel with 256 channel template position. The previous error in channel computing is not appeared but the same error is observed in the dipole localization as you can see:
solver.electrode_1.time_rhs_assembly = 0
solver.electrode_1.linear_system_solver.iterations = 58

Dune reported error: Dune::Exception [findEntityImpl:/home/juan/bst-duneuro/src/duneuro/duneuro/common/edgehopping.hh:84]: coordinate is outside of the grid, or grid is not convex

It seems that you have discussed the issue last year with duneuro team from here but the solution was not found. Do you have any idea on this?
For mac, after remove the argument tetgen1.5, the error is shown below, I thought I could do the same as you suggested, so I reordered 4 5 6 to 3 4 5. The plot color does not seem to be correct, what do you think?
Both Win10 and Mac ended with the dipole error specifically dipole 104 in headmodel computation. I tried using a different electrode template(e.g EGI 128 or 10-10 system 77), the error remains the same.
