The error code that I get executing "check physics" is: The lines :64 65 124 125 of the plan of periodicity have no linked discretisation. The mesh periodicity is not assured. The PERIODICITY PeriodicityNumberZaxis can not be taken into account Lines of the constraint without reference line: To obtain the same line mesh on lines, you may use a LINKED MESH_LINE I'm designing a quarter of a motor. The lines 64, 65, 124 and 125 correspond to the ones on the vertical axis. I'm using the periodicity setting to create the other quarters of the motor so that I get a full one. I've set Repetition number to 4, Offset to 0 and Odd periodicity. The mesh is automatically created with Mesh Faces. It has surface element with 98% of excelent quality and 2% of good. Checking the geometry doesn't give any errors. However I'm concerned that using cartesian and cilindrical coordinate systems on the same geometry may cause this error code. What do you think? I've tried creating a Linked Mesh Line. However It asks me to introduce a transformation that will define that Mesh Line, but I'm using a periodicity so it doesn't appear on the transformations menu. What can I do now? Thanks
Hello, I would like to use periodicities for a toroidal core in Flux3D transient magnetics (12.3). I have set up a simple example with a non-linear steel core and a non-meshed coil. The periodicity is set to cyclic conditions but somehow the magnetic flux won’t concentrate in the steel region. I tried the full model with the same geometry and it looks fine, the flux is concentrated inside the steel region. So there must be a problem with the boundary or the periodicity. How do I have to set up the boundaries/periodicities/formulations to get to correct results? Thanks in advance. Best regards Patrick 3d_core_periodicity_solved.FLU.zip
Hi, I have been working in flux 2d for the past two months. I am now trying to shift to 3d models to explore acoustics and thermal aspects of the induction motor model. I'm using the induction motor overlay and mesh using the mesh domain command with some changes in the aided mesh. I have received the following error message: The PERIODICITY PeriodicityNumberZaxis can not be taken into account Faces of the constraints without reference face: 234 1686 317 502 1386 1389 2063 2014 1489 1700 1753 1854 777 1172 830 1154 1158 865 use the LINKED mesh generator I had encountered similar errors in the 2D modeling as well which used to get solved using a linked mesh line. I tried the same method using the mesh generator and linked the above faces, but it isn't working. I also tried the method of using a complete infinite box which also didn't work. On checking the mesh I received the message attached below which divided the faces into three groups. So I tried applying three different mesh generators and linked each of the three groups separately, which again resulted in the same periodicity error. Also on using the mesh generator I get the message that the faces 1382 and 1686 are linked to themselves. Also how do you set individual faces or volumes that were set as invisible back to visible? Thank you for any time and effort put into helping me out in advance.
