How to change the Element Order

Hi

How can I change the element order? I tried: "mesh.SetElementOrder(5)" but SetElementOrder needs the ElementIds. How can I specify them?

Is it possible to increase just the order of the elements which are used for the holes?

The jupyter sheet is attached.

Kind regards

Michael

Hi,

would you like to have a high order approximation of the circles or a higher polynomial degree in your finite element space?
"SetElementOrder" sets the polynomial order of your finite element.

I just saw a problem with your geometry. If the holes touch the box, the meshing does not work properly.

Best regards,

Hi,

Thank you for the fast response. I will reduce the hole diameter so that the holes don't touch the outer geometry.

I would like to get a better representation of the form of the holes without needing more elements. How can this be achieved?

kind regards,

Michael

Hi,

if you have a NGSolve mesh, you can call the "Curve" function. The argument defines the order of the splines, which are used to approximate the curved geometry.

Best regards,
