• [a] You can post your thoughts quoting the question number.
• [b] Everyone is welcome to post answers and new questions you have faced.

[1]. Have you ever encountered memory leaks or overflows? How did you solve them?

[2]. Have you ever encountered a case where 7 out of 10 calculations were correct, and three were wrong? What is the reason for this?

[3]. If there is a two-dimensional array, should we loop over the first element or the second element first when traversing the loop?

[4]. How is the Riemann solver implemented in the SPH method?

[5]. What are your thoughts on the future development direction of SPH?

[6]. What are the design features of C++?

[7]. How do we deal with the problem of mass non-conservation in SPH multiphase flow problems?

[8]. How is stability defined in SPH?
