Beginne damit, den gemeldeten Fehler unter Linux mit Python 3.10, pymechanical und Transaction() zu reproduzieren. Lies das verlinkte pythonnet issue 79 zur Einschränkung im eingebetteten Kontext und vergleiche es mit dem aktuellen Verhalten von ansys-pythonnet. Als abgeschlossen gilt die Aufgabe, wenn Transaction() das Context-Manager-Protokoll unterstützt, wenn pymechanical eingebettet ist.
