In this tutorial we will compare the performance of the BEM, FEM forward computation in basic model (realistic head model 3 layer) and also within in a spherical head model with an analytical solution.
Describe femVSbem here.
Compare the performance of the mesh resolution vs the leadfield approximation
v10, v1, v0.1 and v0.01 
v0.1 and V0.01 are almost the same ....
difference appears on v10
in spherical head model
same observation on the lf view 
difference appears on the v1 and worse for v10
EEG forward within 3 layers head model :
