I am trying to conduct some analysis in Fluent on a geometry with a cube enclosure of sides 1.26km long. When I open this in ANSYS meshing the program crashes regardless of the computer I use (before any meshing is done) and scaling the geometry down solves the problem. I suspect it is a problem with ANSYS Meshing as colleagues have made similar sized meshes in ICEM before.
I need to conduct my analysis on the full scale model but would like to still use ANSYS Meshing. I notice in Fluent there is the scale function so my question is, can I scale the geometry down by 10%, mesh the smaller geometry then in Fluent scale things up by a factor of 10?
I tried running basic simulations on two different size models using this technique and got different solutions however I am not sure if that is for another reason because I am still relatively new to ANSYS.
Thanks in advance.
