Star not Using Desired Surface Sizes

Hello all,
I am running a sailplane in Star for my Master's research (the novel part being the transition model I'm using) and have had some success. I've decided to go with the trimmer over the polyhedral since it meshes faster and I can put cells where I want them pretty cheaply cell count wise. A problem I've been having is certain boundaries haven't been using the surface size I specify. The fuselage, for example, I specify a target and min of 100% base size but Star generates a mesh with 50% the base size. This happens even if I specify the global min as 100% the base size. I think this started happening when I realized I needed to refine the fuse nose separately of the fuse so I created a new face in the Star CAD model, then updated the parts and updated the region with a new boundary of the fuse nose. Could this corrupt the model to not care about what I specify (or did it change something I haven't noticed)? I'm pretty sure it's happening at the surface remeshing level because if just do a surface mesh the refinement cells are about 50% of the base, but I disabled curvature refinement on the fuse because of some CAD defects so it can't be refining the mesh based on curvature (not that the fuse has high curvature anyway). Any thoughts are appreciated! Thanks, Chris |
