This paper proposes the introduction of a new initialSimplified() operator in Modelica, which allows to solve inverse problems with the same reliability as direct problems, using an intuitive, straightforward Modelica formulation. The proposed solution can be trivially implemented in Modelica tools and will be 100% portable among them, once the new operator is standardized. The usefulness of the proposed approach is demonstrated on a conceptual thermal power generation plant model. https://www.hsbi.de/publikationsserver/download/7257/7258/AMFC2026_paper_T1S2P1.pdf application/pdfno Linköping University Electronic Press2026Hangzhou, China eng Modelica languageinitializationhomotopyconvergence problems urn:nbn:de:hbz:bi10-7257010.3384/ecp22331 223 72572026-10-31T14:00:35Z2026-10-31T14:01:59Z
