Coupling Maxwell to a Twin Builder Component

Maxwell designs may be dynamically coupled to Twin Builder components through the Twin Builder user interface. The Twin Builder interface allows Maxwell 2D, 3D, and RMxprt designs to be linked as dynamic components. Source windings set to External are available as conservative pins in Twin Builder.

• Transient coupling links must be enabled in Maxwell on the Design Settings > Advanced Product Coupling tab for Transient Cosimulation with Twin Builder.

  

• For parametric HPC solve of Maxwell 2D and 3D transient coupling designs, HPC setup must be done on the Twin Builder side. Maxwell will use the same HPC setup from Twin Builder; and any HPC settings on the Maxwell side will be ignored. The Twin Builder HPC setup includes user inputs for Number of tasks and Number of cores. Specify the task number to be greater than 1; and the core number to be equal or greater than the task number. Only one level HPC (Optimetric Variations) is supported. OpenMP is supported. For OpenMP, the number of cores divided by number of tasks should be greater than 1 (multiple cores per task).

  

  Note: A variable, TBOptiVariation, will be added in the Maxwell design for such cosimulation. A warning message will display when this variable is added to the Maxwell design for the first time. Any changes in the Twin Builder design will reset the value of the variable to 0 and Maxwell solutions will be invalidated.

• The ECEIM_Model component must be used in a Maxwell eddy current design to enable Twin Builder to couple to the design.

Dynamically linked components provide the ability to have Twin Builder vary a variable in a Maxwell design and have Maxwell solve the design at the new design point and provide the solution data back to Twin Builder for use in the circuit simulation.
