I have rerun this with a simple cylindrical geometry, and still see the same “unphysical” behaviour where particles are at the outlet initially, in addition to odd arithmetic errors linked to file saving. This is a bit of a headache, because none of these problems were present in the quite similar 2D simulations I ran until now, and seems not to be a problem in the 3D TFM tutorial either.
