Module plot3d_format 

PLOT3D format for CFD grid and solution files.

Supports multi-block structured grids in ASCII PLOT3D .xyz and .q formats as commonly used in CFD solvers.

File layout

Grid file (.xyz)

`nblocks`
`ni1` `nj1` `nk1`  [`ni2` `nj2` `nk2` …]
<x values block 1> <y values block 1> <z values block 1>
…

Solution file (.q)

`nblocks`
`ni1` `nj1` `nk1`  [`ni2` `nj2` `nk2` …]
`mach` `alpha` `rey` `time`   (per block)
`rho` <rho*u> <rho*v> <rho*w> `e`  (per point, per block)
