Solving problems

Hi all,

I have a problem solving the project in the image below.

It is a machine in which the mechanical set of the green face and the red face is set in 'translation along Ox'.

The surrounding face (the face selected in the image) is air. Now, if the mechanical set of this face is setted 'fixed', the following solving error appears: ' executeAlgo_c : Execution failed'.

Instead, if I change the mechanical set into 'compressible', the error message is: 'Unable to rebuild device because symmetries/periodicities create an infinite geometry'.

I think I didn't understand completely the meaning of these mechanical sets or I made some errors with the periodicity. What can I do?

Thank you everybody.

Hi, it seems a periodicty problem. How you define the periodicty in your model?

Hi Federico,

I defined the periodicity 'Translation along x' and I defined all the lenght of the machine in the x axis.

clink on View > Full Device. Flux will show you the full model, building (only visually) the periodicity and the symmetry defined.

In your case will appear 'Unable to rebuild device because symmetries/periodicities create an infinite geometry' because, for the periodiciy, FLUX replicate every L_STAT/2 your model, with no limitation of the number of replication, the device is infinite

Ok, so I suppose the parameters setted for the periodicity are not correct. How can I modify them? This is a part of an axial flux motor simulated in 2D, so I have really no idea how to fix it.
