Worked on enhancing the reliability of the RWTH-EBC/AixLib repository by addressing compilation warnings in the DistrictHeatingCooling/Pipes module. Focused on library maintenance and Modelica development, the work involved enforcing a minimum m_flow_small value across all relevant pipe models to align with the PartialTwoPortInterface. This technical approach unified flow rate constraints, reducing the risk of runtime errors and simplifying future maintenance. By adapting the m_flow_small definition, the changes improved cross-model consistency and mitigated discrepancies during integration with other components. The contribution centered on bug fixing rather than feature development, emphasizing robust constraint management within the Modelica modeling environment.
