Dear all,

this is just a friendly reminder about the changed presentation for tomorrow and a thank you for allowing me to talk about some of the refinement boundary issues that we have for the binary black hole accretion simulations instead. Thanks especially to Liwei who planned to talk about SC before.

I am very grateful for all of your input tomorrow on the progress we had so far and the problems that still remain 🙂

Best,

Michi

It would be really helpful if you can merge it to the main branch.

Dear Erik, Roland,

 

Hope you are doing well.

I wanted to follow up on our discussions in today’s CarpetX call.

As you mentioned, there was some development related to improvising the prolongation operators in CarpetX.

 

Could you kindly give us some update about this (this is also for people in cc who were not in today's call)? 

Also, if there are any new operators implemented that we could test, that would be quite useful for us. Let us know.

We would be very grateful for your input. 

Thank you very much!

Kind regards,

Jay
