diff test/SbpOperators/volumeops/derivatives/second_derivative_test.jl @ 2080:0f949681d3d3 refactor/sbp_operators/direction_check tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Check that direction of first/second derivative operators is within the dimension of the grid. Add 1D functions for first/second derivative operators that take a direction.
