Coefficient for coils flux computation

기존의 FLUX3D 에 있던 기능이 FLUX2D 에 통합된 기능으로 , ¼ 모델과 같은 부분모델을 외부회로와 링크할 때 , 기존에는 부분모델에 맞게 저항과 인덕터는 실제 값을 나누어 주고 , 커패시터는 값을 곱하여 입력해 준 후에 결과는 반대로 곱하거나 , 나누어서 결과를 얻어냈으나 , FLUX 9.1 에서는 전술한 과정이 필요없이 Coefficient for coils flux compuation 를 이용하여 변환과정없이 값을 입력해주며 , 계수는 자동과 수동으로 설정이 가능하다 .

로터 또는 스테이터 슬롯의 스큐는 스테이터에 대한 로터의 방향변화에기인한 자기장의 축방향 변화때문에 2 차원의 문제로 표현될 수 있으며 ,‘Multilayers’ 라 불리는 수치해석기법에 따라 모델링되고 ,FLUX 에서는 이를 準 3 차원 (Quasi-3D) 또는 2½ 차원 (2½D) 이라 표현한다 .
