MainParametric modeling Parametric modeling with LabelMoverLabelMover is a powerful tool for simple parametric study of QuickField models. This utility is based on ActiveField and works in three modes: Serial, Tolerance and Optimization analysis.Serial Analysis mode generates the series of QuickField problems with specified alterations of the model geometry or physical properties, solves these problems and presents results as a table or graph.Video: QuickField LabelMover serial calculations. Watch on Youtube Serial analysis of the Solenoid Actuator simulation example.Tolerance Analysis is a study of the result parameters variation caused by the manufacturing inaccuracies and unstable material properties. After the base QuickField problem is formulated and solved, LabelMover automatically generates and solves the series of QuickField problems required for analyzing the results distribution caused by variations of the input parameters, and calculates related statistical characteristics.Video: Tolerance analysis with LabelMover. Watch on Youtube Tolerance Analysis of Solenoid Actuator simulation example.Optimization greatly simplifies design tasks of adjusting multiple model parameters to reach the specified goal. It is possible to set any value provided by QuickField postprocessor as a goal for "maximum", "minimum" or "closest to specified value". In addition to using internal optimization algorithms, LabelMover Optimization may work with external applications, implementing other optimization algorithms, or simply be used to control one step of QuickField problem modification, regardless of the goal. Both object and command string application programming interfaces are provided.Video: Optimization with LabelMover. Watch on YoutubeSolenoid Actuator optimization simulation example.LabelMover may be applied to any preliminary defined QuickField problem, and is compatible with both free QuickField Student Edition and QuickField Professional Edition.

MainTera Analysis Ltd. New QuickField International Distribution center has been established in Denmark.The goal of the new company is to market, distribute and support QuickField software internationally. All orders for QuickField software placed by customers who are based outside of North America (USA and Canada) will be processed and shipped from this new center. Through this reorganization, we hope to decrease the software delivery time and substantially increase the quality and timeliness of the support for our customers.From now, Tera Analysis Company (LA, California, USA) will be responsible for North American market only, and Tera Analysis Ltd (Svendborg, Denmark) will handle all the International sales and support. Both companies will collaborate in QuickField software development, marketing and support. We believe that this partnership will strengthen QuickField's position in CAE software market and would be beneficial for our existing and future customers.A note on existing orders: all the sales and purchase orders that have been issued up to this date, would still be invoiced by Tera Analysis company in USA and the invoices have to be paid to Tera Analysis Company in US account.

MainSolenoid actuator simulation QuickField simulation exampleThis is an example of the solenoid actuator simulation, performed with QuickField software.A solenoid actuator is an example of electromechanical transducer, which transforms an input electric signal into a motion. Solenoid actuator, considered here, consists of a coil enclosed into a ferromagnetic core with a moving part - plunger inside. Actuator design requires calculation of the magnetic field and a force, applied to the plunger.Problem TypeAxisymmetric problem of DC magnetics.GeometrySolenoid actuator forceA solenoid actuator is an example of electromechanical transducer, which transforms an input electric signal into a motion.PlungerCoreCoil +Coil -24 cm20 cm4 cmØ24 cmØ8 cmGivenRelative permeability of air and coil μ = 1;Current density in the coil j = 1 A/mm²;The B-H curve for the core and the plunger: TaskObtain the magnetic field in the solenoid and a force applied to the plunger.SolutionThis electromagnetic transducer magnetic system is almost closed, therefore outward boundary of the actuator model can be put relatively close to the solenoid core. A thicker layer of the outside air is included into the actuator model region at the plunger side, since the magnetic field in this area cannot be neglected. Mesh density is chosen by default, but to improve the mesh distribution, three additional vertices are added to the actuator model. We put one of these vertices at the coil inner surface next to the plunger corner, and two others next to the corner of the core at the both sides of the plunger. A contour for the force calculation
