Specifically, as the mean free path of the photons tends to zero this simulation depicts the formation of boundary layers and the fact that at the interior of the domain the radiation intensity becomes isotropic solving a Laplace equation. This numerical simulation supports the results obtained analyzing the radiative transfer equation via matched asymptotic expansions.</abstract><sumDscr/></stdyInfo><method><dataColl><sources/></dataColl><anlyInfo/></method><dataAccs><setAvail/><useStmt/><notes type="DVN:TOU" level="dv">&lt;a href="https://mit-license.org/">MIT&lt;/a></notes></dataAccs><othrStdyMat/></stdyDscr><otherMat ID="f11841" URI="https://bonndata.uni-bonn.de/catalog/downloads/11841/code.py" level="datafile"><labl>code.py</labl><txt>This document contains the Python code for the simulation</txt><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">text/x-python</notes></otherMat><otherMat ID="f11843" URI="https://bonndata.uni-bonn.de/catalog/downloads/11843/Licence.txt" level="datafile"><labl>Licence.txt</labl><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">text/plain</notes></otherMat><otherMat ID="f11840" URI="https://bonndata.uni-bonn.de/catalog/downloads/11840/Plot.png" level="datafile"><labl>Plot.png</labl><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">image/png</notes></otherMat><otherMat ID="f11842" URI="https://bonndata.uni-bonn.de/catalog/downloads/11842/Readme.pdf" level="datafile"><labl>Readme.pdf</labl><txt>This document describes the analyzed problem and the method used in order to develop the simulation.</txt><notes level="file" type="DATAVERSE:CONTENTTYPE" subject="Content/MIME Type">application/pdf</notes></otherMat></codeBook>
