I wonder if the precision problem will still exist if&nbsp; I export the solution data&nbsp; into other post-processing software like cfd-post, paraview, ensight though I seldom use them.????&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-358591","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 4.9.10 - aioseo.com -->\n\t<meta name=\"description\" content=\"Hello Federico,I use double precision all the time and I also change the unit to the same one everytime I read the mesh.
