Can I use PDEModelica for calculations in 2D domains. How many domains PDEModelica supports, or DomainLineSegment1D only? I use OpenModelica.
Seems not. https://openmodelica.org/doc/OpenModelicaUsersGuide/latest/pdemodelica.html
PDEModelica1 is nonstandardised experimental Modelica language extension for 1-dimensional partial differential extensions (PDE).
