abaqus中的approximate size是什么意思

Abaqus/CAE uses a geometry engine to model parts and features. The recommended approximate size limits are between 0.001 (10^–3) and 1000 (10^4) [sic] units. This size range should prevent your model from exceeding the limits of the geometry engine. For example, the minimum size supported by the geometry engine is 10–6, so maintaining geometry on the order of 10–3 will normally allow node and element dimensions to remain above the minimum size. Parts that exceed the recommended limits may exhibit geometric defects. If you find that you need to specify an approximate size that is outside the suggested range, you should consider adopting a different set of units.
