Description
We evaluate the accuracy of 1-D spherical and 2-D cylindrical geometry transport discretizations in thick diffusive regions by means of a matrix asymptotic analysis. We show that two methods, ''simple'' corner balance and a ''fully-lumped'' discontinuous finite element method, are accurate, both in the interior of these regions and on boundaries. We give numerical results to illustrate our findings
