Der Artikel unseres Doktoranden Aqeel Chaudhry ist unter den Top 10 Downloads im International Journal for Numerical and Analytical Methods in Geomechanics.
Numerische Modelle werden oft anhand analytischer Lösungen verifiziert. Für thermisch-hydraulisch-mechanisch gekoppelte Probleme gibt es wenige solcher Lösungen. Ein in der Literatur häufig verwendeter Verifikationsfall ist die Punktwärmequelle im isotropen Medium, für dass 1985 eine THM Lösung hergeleitet wurde. Diese Publikation enthielt jedoch Fehler in der Spannunsberechnung, weswegen sich die Verifikation der THM Codes häufig auf die Verschiebungs-, Temperatur- und Porenwasserdrucklösung beschränkte. In seinem Artikel leitet Aqeel Chaudhry die Lösung sauber her, beseitigt Inkonsistenzen in der Notation und korrigiert die Spannungslösung. Die Lösung wird beispielsweise im Projekt DECOVALEX verwendet, um THM Codes zu verifizieren, und dient als Benchmarkproblem für die Quantifizierung von Ungewissheiten in gekoppelten Prozessen.
Von Januar 2019 bis Dezember 2020 gehörte das Paper laut Verlagshaus Wiley zu den zehn am meisten heruntergeladenen neu publilizierten Artikeln im International Journal for Numerical and Analytical Methods in Geomechanics. Wir gratulieren Aqeel herzlich zu dieser großartigen Leistung!

The article of our PhD student Aqeel Chaudhry is among the top 10 downloads in the International Journal for Numerical and Analytical Methods in Geomechanics.
Numerical models are often verified using analytical solutions. For thermal-hydraulic-mechanical coupled problems, there are few such solutions. A frequently used verification case in the literature is the point heat source in an isotropic medium, for which a THM solution was derived in 1985. However, this publication contained errors in the stress calculation, so the verification of the THM codes was often limited to the displacement, temperature and pore water pressure solution. In his article, Aqeel Chaudhry derives the solution cleanly, removes inconsistencies in the notation and corrects the stress solution. The solution is used, for example, in the DECOVALEX project to verify THM codes and serves as a benchmark problem for quantifying uncertainties in coupled processes.
From January 2019 to December 2020, the paper was among the top ten most downloaded newly published articles in the International Journal for Numerical and Analytical Methods in Geomechanics according to the publisher Wiley. We warmly congratulate Aqeel on this great achievement!
