  1. Dear @Abdessamed , Thank you for your efforts to help me. I took a look at the file that you uploaded. The file indeed represents the 3-D axisymmetric implementation of the device that I uploaded, however, all geometric parameterization is lost. Note that for this 3-D study, it is instrumental to preserve the possibility to adjust the geometric parameters. At least the parameter `ECC' has to be available for adjustment. This because the goal of the 3-D analysis is to study the effect of shaft (and thus translator/mover) eccentricity on the radial attraction force between the stator and the translator. Perhaps @lombard can help me out? Or @Alejandro Rodríguez ?
  2. Using the `rotation` transformation, Flux throws an error upon the creation of faces and volumes. Moreover, a rotation uses a line of symmetry, so for the mover and the region of compressible air around the mover, this transformation cannot be used.
  3. I would like to quantify the effect of the eccentricity of the translator of the attached actuator. The device is a 2-D axisymmetric reluctance actuator. The attached simulation only contains the permanent magnet, the pole shoes, and the core. I am only interested in the effects between the permanent magnet and the steel parts. I failed to create a 3-D FLUX file that captures the eccentricity of the translator (composed of the permanent magnet and the pole shoes). Any help would be appreciated.

  4. Thank you for your reply. However, I think you misunderstand the question. A face region, e.g. COIL, which has the property of a 'coil conductor region' can only be connected to one single electric circuit component and this property cannot, as far as I know, be adjusted to a 'solid conductor region' in a time-stepping scenario be means of a switch. A face region cannot be linked to two electric circuit components either. So switching between electric circuit components in the electric circuit will not alter the electric circuit component to which the face region is connected.
  5. In a Transient Magnetic 2D Axisymmetric simulation, a solid movable piece of steel is attracted upwards by the combined forces of permanent magnets and a coil. The coil is represented in the associated electrical circuit as a coil conductor with one turn, and its resistance is equal to that for one turn as well. Current through the coil conductor is imposed by a current source. Now, once the mover has moved half of the required distance, the magnetic circuit should start to act as a brake (or damper), rather than an actuator. Hence, by passive means, the speed of the mover should be reduced. I would like to achieve this by short-circuiting the coil, and using it as a solid conductor. However, this requires to switch from one electrical circuit implementation, to another one. In the second electrical circuit, there is no current source anymore, and the coil is represented as a solid conductor (to act like a solid piece of copper). Can someone explain how I can implement both of these situations in the same Flux simulation? @Flux support @lombard
