Plecs Trial License

To prevent indefinite free use, the trial license imposes specific technical restrictions:

| Restriction | Detail | |-------------|--------| | Circuit size | Limited to 15 electrical state variables (e.g., capacitor voltages, inductor currents). This is the most impactful limitation. | | Simulation time | No arbitrary time limit per run, but large circuits may not fit within state limit. | | Code generation output | Generated C code will expire 1 hour after compilation (i.e., executable stops after 1 hour of simulated time or 1 hour runtime). | | Save/Load of models | Models can be saved and reopened, but cannot be edited in a new session after the trial expires. | | No commercial use | The trial license is strictly for evaluation; results cannot be used in commercial product releases. | | Watermark | No visible watermark, but exported plots may contain a small evaluation notice (version dependent). | plecs trial license

After using the PLECS trial license, you will likely see the value. But is the investment worth it compared to open-source (like OpenModelica) or basic Simulink? To prevent indefinite free use, the trial license

Solution: This is not a license issue; it's a modeling issue. Use the Delay block in the control section or manually set a preferred solver (e.g., Trapezoidal vs. Backward Euler) in the Simulation Parameters dialog. The trial version gives you full access to tweak these settings. No, if: You will be asked to provide:
