We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi,

No, symmetry and periodic boundary conditions are not similar. While symmetric boundary conditions mirror the behavior of the system across the boundary, periodic boundary conditions assume the system repeats itself beyond the boundary. The choice between them depends on the specific characteristics of the system being modeled and the requirements of the simulation or mathematical analysis.
