[1] 14:48:00 Symbolic Warning The model contains alias variables with redundant start and/or conflicting nominal values. It is recommended to resolve the conflicts, because otherwise the system could be hard to solve. To print the conflicting alias sets and the chosen candidates please use -d=aliasConflicts. [2] 14:48:00 Translation Error Internal error IndexReduction.pantelidesIndexReduction failed! System is structurally singular and cannot be handled because the number of unassigned equations is larger than the number of states. Use -d=bltdump to get more information. [3] 14:48:00 Translation Error post-optimization module replaceHomotopyWithSimplified (initialization) failed. [4] 14:48:00 Translation Error No system for the symbolic initialization was generated

The model had some issues that were fixed in MSL 4.0.0, see report. However, we still do not support that library, until coversion scripts are ready #5297.
The fix was back-ported to MSL 3.2.3 maintenance, it is still in the pipeline, see [MSL PR 3600], please follow it there. Once the fix is released, we'll incorporate it automatically in OpenModelica
