20-sim 4.7.1

20-sim 4.7.1 has been released. This build is a maintenance release with the following fixes:

 

Documentation

    Improved: Imported FMU submodels now show FMI documentation when pressing F1
    Model help did not open webpage URLs anymore

Editor

    Improved: Zooming with Ctrl+MouseWheel has now more intermediate steps
    Improved: Dissolve of a splitter should introduce an additional intermediate point in the new signal connection if it is located at a corner
    Fixed: port name tool-tips were not working anymore
    Fixed: FMI import: calculated fixed parameters should not be set
    Fixed: FMI import went wrong when the active model is stored in a read-only folder

Processing

    Fixed: static matrix index expressions did not longer work.

3D-animation

    Fixed: Non-existing STL files were continuously checked for, resulting in a lower FPS

Simulator

    Fixed: early stop of a running simulation took multiple seconds on certain PCs

Scripting

    New: Add support for Octave 4.2.2 and 4.4 (both x86 and x64 Windows)

Code Generation

    Fixed: C-code generation of encrypted submodels
    Fixed: unexpected rounding errors in generated double literals for certain integer values

New! 20-sim 4.7

20-sim 4.7 has been released on March 2, 2018. Read all about this new version here.

We’re adjusting pricing on March 1

We’re adjusting pricing on March 1st


Controllab will be adjusting the prices for 20-sim and 20-sim 4C beginning March 1. The average price raise in euros will be 5%. This reflects the cumulative inflation since we have last raised our prices in 2014.
 
If you want to lock in on our old pricing before the change is made? You can purchase new software or renew your annual maintenance contract before March 1 and we’ll honor our old prices. Just send us a PO before March 1st.

If you are interested in upgrading to a newer version of 20-sim, we'd be happy to honor our previous pricing till the mentioned date.
 
Do you have any questions or concerns? Just send us an email. We’ll get back to you quickly.
 
Thanks always,

20-sim 4.6.4 has been released. This build is a maintenance release with the following fixes:

4.6.4 (build 8004, July 26, 2017)

3D Animation

  • Fixed: Range issue in Spot Angle.

Code Generation

  • Fixed: Directly mapping to an R(ate)-variable if a submodel takes the integral/previous of an input.
  • Fixed: Initial equations in a FMU cannot influence initial states.
  • Fixed: Crash when running a generated FMU in a FMI 1.0 master simulator.
  • Fixed: FMU 2.0 Export: Table2D implementation for source code FMU does not work on Linux/MacOSX

Documentation

  • Reference Manual: Fixed: Unclear statement about 'while do' and 'reapeat until'.
  • Reference Manual: Fixed: Orientation of Euler angles in 3D animation window (ZXZ instead of XYZ).

Simulator

  • Fixed: Not saving a model when closing 20-sim during a simulation.
  • Fixed: A issue when writing a data file of multiple run results (parameter sweep).
  • Fixed: A issue that unnamed nodes can generate instructions for a continuous time block instead of the corresponding discrete block.
  • Fixed: A crash during a multiple run simulation with parameter sweep.
