Dear Daniel, I am working on a similar problem (planetary acoustic oscillations). I am interested in looking at your tutorial for an electromagnetic cavity, but it seems that the pull request was deleted. I wonder if it can be revived. Thank you, Anton. On Monday, July 8, 2019 at 3:51:08 AM

Sabyasachi, it took me a while to understand that what you are asking is not actually a question about deal.II but about how to do what you are suggesting in C++. The relevant part of the setup_q_point_data() function in step-18 is this: quadrature_point_history.resize(

@Wolfgang: I commented out that lines, compiled deal.II and it looks OK, at least `make test` passes and step-37 works in both release and debug mode. @Marc I had the same idea, but there was nothing in `configure --help` to put custom zlib patch. Thank you for the answers. For reference, I

Mariia, I also tried fixing this within deal.II and discovered that some more changes are necessary, see https://github.com/dealii/dealii/pull/12761. Would you mind checking if the changes proposed there work for you? Best, Daniel Am Fr., 17. Sept. 2021 um 06:25 Uhr schrieb Мария Бронзова <
