Release Notes for OpenModelica 1.11.0

  1. OpenModelica Compiler (OMC)
  2. Graphic Editor OMEdit
  3. OpenModelica Notebook (OMNotebook)
  4. Optimization
  5. FMI Support
  6. OpenModelica Development Environment (OMDev)
  7. Detailed Changes

The most important enhancements in the OpenModelica 1.11.0 release:

OpenModelica Compiler (OMC)

New features:

  • Real-time synchronization support by using simFlag -rt=1.0 (or some other time scaling factor).
  • A prototype implementation of OPC UA using an ​open source OPC UA implementation. The old OPC implementation was not maintained and relied on a Windows-only proprietary OPC DA+UA package. (At the moment, OPC is experimental and lacks documentation; it only handles reading/writing Real/Boolean input/state variables. It is planned for OMEdit to use OPC UA to re-implement interactive simulations and plotting.)

Performance enhancements:

  • Code generation directly to file (saves maximum memory used). #3356
  • Code generation in parallel enabled since #3356 allows this without allocating too much memory (controlled by omc flag -n).
  • Various scalability enhancements, allowing the compiler to handle hundreds of thousands of equations. See for example ​ScalableTestSuite for some of the improvements.
  • Better defaults for handling tearing (OMC flags --maxSizeLinearTearing and --maxSizeNonlinearTearing).
  • Allowing mixed dense and sparse linear solvers in the generated simulation (chosen depending on simflags -ls (dense solver), -lss (sparse solver), -lssMaxDensity and -lssMinSize).
