Hi there. I notice that the Magnetic Transient solver does not have an Adaptive Meshing function. This seems a real limitation for this solver, are there plans to improve this? In the meantime, as a workaround, I am creating a good quality Adaptive Mesh in the Magnetostatic solver, then "eyeballing" it to see where the mesh is most detailed, and then attempting to create regions in my Transient model which, as closely as possible, matches the Magnetostatic Adaptive Mesh. This is far from ideal, is very time consuming, and the accuracy of the result is very low. So I am looking for a better solution. I notice in the Transient Solver options there is an 'Advanced' tab with an 'Import Mesh-Set-Up' button. I wonder whether I can link the Transient design to the Magnetostatic design in order to generate the Adaptive Mesh to use in the Transient design? The two models are identical, except that the Transient design has a 'Band' with movement. Under 'Source Design' I choose the Magnetostatic solver. Under 'Variable Name', I have clicked 'Map Variable by Name', hoping that the two models will connect. However, when I start the transient simulation, I get errors 'The source design has transient-transient link enabled and cannot be linked to other design. Fail to get presolved data.'. My model is a rotor moving past a stator with a coil at a fixed current (see picture with Adaptive Mesh). I am interested in the force of the attraction that the stator exerts onto the rotor. If anyone can help it would be much appreciated :)May 17, 2022 at 9:37 pmHDLIAnsys Employee
To link two solvers, the geometry should be same. I suggest to build the transient model, make everything correct in the transient model, and then copy it to build the source model.
I am not sure why you want to use the magnetostatics solver for a motor, but this solver would not support the magnet.
Additionally, either the magnetostatics or eddy current would not support the motion, so the linked mesh might not be sufficient for transient when there is moving object(s).One example, in the first design (static or eddy), the adaptive mesh may come up with dense mesh in certain areas but less so in others, when objects move away, some of these meshes may not be enough while others will become overkill.
If the air gap is smooth and identical, this liked mesh would be good to use. Thanks.
