Dear Prof. Sherwin

     Yes, I have tried using both the localtoglobal approach and the standard mass matrix inverse and both dont work. If I interpolate one field with variable polynomial order to a field with identical polynomial order, will it be an alternative choice?

Many thanks,

主题: Re: discontinuous results when using ariable polynomial order

Hi Zhaoyu,

I am not sure what to suggest in this case. The techniques should also work in this case but I doubt they have been full tested in this scenario. Have you tried using both the localtoglobal  approach and the standard mass matrix inverse and both do not work?

Cheers,
Spencer.

Dear Prof. Sherwin

   Thanks for your reply. There is a problem is when I use variable polynomial order in the field, the results near the boundary between 2 domains with different polynomial order cant be smoothed by C0projection

module. So how can I handle the discontinuous results in this case?


Many thanks,
