id summary reporter owner description type status priority milestone component version resolution keywords cc 5357 Evaluating structural parameter (or constant) - Translation Error KieranF somebody "I recently tried to instantiate the WindFarm.mo located within PowerSystems.Examples.Wind.WindFarm and I received an error message reading: [1] 10:03:42 Translation Error [PowerSystems.AC3ph.Machines: 2208:3-2208:47]: Could not evaluate structural parameter (or constant): wt1.generator.c.n_r which gives dimensions of array: L_r. Array dimensions must be known at compile time. This error was just really confusing to me because no where within the WindFarm.mo was there a use of any model from PowerSystems.AC3ph.Machines library. All the components used within the WindFarm.mo does indeed have components used within PowerSystems.AC3ph however, that is where it ends. The variable ""n_r"", I believe the rotor speed, is not even used within my model. If you have any knowledge in this subject, advice or suggestions please feel free to leave a comment! Thanks!" defect closed high Future *unknown* invalid
