[Getdp] unable to cross the air-gap

Thank you for your answer, but then everything is air except the magnet and
there is no more air-gap.

 

With the commercial software I have access to at KST, I get this result :

 



 

And I wanted to have the same kind of result with GetDP J .

Hello,

 

in the simple 2D magnetostatic model attached to this e-mail, the magnetic
induction “refuses” to cross the air-gap.

 

 

It seem normal to me,

due to the magnetic short circuiting of the permanent magnet.

Try with murCore = 1 (instead of 200) and the field lines

will gently cross the air gap.

 

Regards,

 

François

 





Could someone tell me why it is so and explain me what I need to change.

 

(to solve the model I use this command : ‘getdp machine2 -solve MagSta_a
-pos a’)

 

Thanks in advance for any answer.

 

Joseph
