| integer(kind=4), | intent(out) | :: | n_x | the number of mesh elements |
||
| real(kind=8), | , | dimension(:), allocatable | :: | x | the mesh midpoints |
creates a nonuniform mesh with size varying from delta_x_min on the left edge of the boundary to delta_x on the right edge of the boundary. The element sizes vary as \(\log\left(\frac{a}{a^{n}}\right)\)
