Workaround for 2021 multi-core: Partition plant into subsystems, run in parallel using Channel Wires or TDMS streaming to separate loops.
| Feature | 2018 | 2021 | |---------|------|------| | Variable-step solvers | Limited (ode45, ode23) | Expanded (ode15s for stiff systems, ode113) | | Event handling | Manual via discrete logic | Built-in zero-crossing detection | | Simulation performance | Single-threaded by default | Parallel simulation support for Monte Carlo runs | | Model linearization | Requires Linearization VI | Trim & Linearize App (interactive GUI) |

Here’s a helpful, structured guide to understanding and using the LabVIEW Control Design and Simulation Module for versions 2018–2021. If you want, I can:
Note: NI (now part of Emerson) rebranded this module. In 2021, it became part of the LabVIEW Control Design and Simulation Module (same name). From 2020 onward, it requires the LabVIEW Professional development system.
The fluorescent lights of the university robotics lab hummed in competition with the whine of cooling fans. It was 2:00 AM. Elias, a PhD candidate, was staring at a block diagram that looked like a bowl of neon spaghetti.
His thesis depended on a bipedal walking robot. The goal: make the robot balance on one leg without shaking itself to pieces. a PhD candidate
Key Focus: Model Import/Export and Python Integration
By 2020, NI recognized that not everyone wants to build models from scratch in LabVIEW. Many engineers develop plants in MATLAB/Simulink or Python (with SciPy/Control libraries). The 20.0 release added robust FMI (Functional Mock-up Interface) support for version 2.0 Co-simulation and Model Exchange.
This meant:
Additionally, a new Python Node for Simulation allowed calling Python control libraries (e.g., control.matlab transfer functions) from within a simulation loop. This was a practical bridge for research teams prototyping in Python but deploying in LabVIEW RT.
