<p data-start=”183″ data-end=”203″>Hello,<\/p><p data-start=”205″ data-end=”352″>I have a 2D geometry that is divided into three adjacent regions. For my Fluent setup, I need different topology connections between these regions:<\/p><ul data-start=”354″ data-end=”529″><li data-section-id=”19pl6o1″ data-start=”354″ data-end=”424″>the <strong data-start=”360″ data-end=”381″>upper two regions<\/strong> must be connected with <strong data-start=”405″ data-end=”424″>shared topology<\/strong><\/li>\n

<li data-section-id=”esoaou” data-start=”425″ data-end=”529″>the <strong data-start=”431″ data-end=”453″>large lower region<\/strong> must remain only <strong data-start=”471″ data-end=”482″>grouped<\/strong> with the adjacent region, not shared or merged<\/li>\n<\/ul>\n

<p data-start=”531″ data-end=”760″>The problem is that when I set it up this way, the mesh at the interface between the grouped regions is <strong data-start=”635″ data-end=”652″>not conformal<\/strong>.
