Several additional parameters for controlling the mesh distribution are provided on the Advanced Meshing Controls dialog. To open it, click Advanced on the Automatic Sizing context panel. These define constraints that affect the behavior of the Automatic Mesh Sizing facility globally.
These parameters should be used with caution as they may have a significant impact on the resulting mesh. The Resolution Factor controls the relative fineness of the mesh in response to the curvature of model entities. Though this parameter has global scope, the effects are localized to regions of high curvature. Smaller values result in a finer mesh on model entities with curvature. Regions with no curvature are not affected by this parameter.
The default value is 1. Values outside of this range are rejected. This controls the quality of the distribution computed by Automatic Sizing. It autodesk cfd advanced 2019 free download the rate at which point distributions may expand or contract along an /713.txt. This parameter influences distributions along individual edges autodesk cfd advanced 2019 free download well as distributions between edges.
The net effect is that controlled blending is introduced along and across model entities. The default Local Stretching value is 1. For entities lacking curvature, a minimum level of resolution is guaranteed by this parameter. Increasing this value autodesk cfd advanced 2019 free download the minimum number of nodes on an edge. This is a constraint autodesk cfd advanced 2019 free download not a prescription on the computed resources. If a small edge is in close proximity to a highly curved entity, these smaller length scales may drive the autodesk cfd advanced 2019 free download on the small edges to be higher than the prescribed minimum value.
This parameter controls the minimum number of points on the longest edge in the model. It is most relevant for geometry with no curvature such as the surrounding box for an external flow.
This setting may be superseded by the influence of length scales on other model edges in conjunction with how the local stretching constraint dictates a smaller length scale. This may cause more points on the longest edge than the value specified by the Points on Longest Edge parameter. Used during Automatic Sizing, this affects the distributions on edges bounding high aspect-ratio surfaces.
During Automatic Sizing, surfaces identified by the Diagnostics facility are autodesk cfd advanced 2019 free download to ensure that the distributions generated for the bounding edges reflect length scales whose size is no greater than the product of the computed separation distance and the Surface Limiting Aspect Ratio.
This limiting length scale may be smaller than that derived from the local curvature, and if so, the distributions are based on this constraint. Use this parameter to introduce a further constraint on length scales to ensure they are not larger than a specified factor of the dimensions of the surface. This can significantly enhance the robustness of the meshing operation. Any value greater than or equal to 1 is permitted for this parameter.

A value of 1. Minimum points on edge For entities lacking curvature, a minimum level of resolution is guaranteed by this parameter.
Points on longest edge This parameter controls the minimum number of points on the longest edge in the model. Surface limiting aspect ratio Used during Automatic Sizing, this affects the distributions on edges bounding high aspect-ratio surfaces. Volume growth rate Specify a value between основываясь на этих данных. For example, a value of 1.
Note: Click the Refine button after modifying any of these settings:. Surface growth rate and Enhancement growth rate To control the growth of surface elements, modify the Surface growth rate. The default value of 1. Gap Refinement To control the approximate number of elements across a gap not including the mesh enhancement layersenter a value for Fluid gap elements. To force a coarser mesh in thin solids, specify a value less than 1.
The reciprocal is how much the surface faces grow relative to the volume elements. A value of 0. To mesh important gaps with a fine mesh, reduce the Gap refinement length smaller than the gap: To mesh irrelevant gaps with a coarse mesh, increase the Gap refinement length larger than the gap: The Gap refinement length applies to all gaps in the model.
It is not possible to target individual gaps for refinement.
