Hello,<\/p>\n

<\/p>\n

I am attempting to model the airflow through a cold trap see in the picture below:<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

Air is supposed to enter the top nozzle, travel down the tube into the reservoir region, then proceed back up the assembly to the outlet.<\/p>\n

<\/p>\n

I initially, had these separated as two separate parts, where the cutout region was created by a Boolean subtract. However, when transferring the mesh to FLUENT an error occurred in which the contacting surfaces of the meshes had issues. I saw there was a section in FLUENT that allows you to make a relationship between these two regions, but I don’t know the correct one to use. They are simply stationary walls, that should restrict the flow path to the one described above. <\/p>\n

<\/p>\n

I had both parts described as fluids because I ran into an earlier error where there were illegal fluid-solid zone interactions. Would listing them as both solids, but using named selections to create a fluid volume instead?<\/p>\n

<\/p>\n

The second approach I tried was to combine the parts into one, to ensure a conformal mesh along that interface. This worked great until the solution showed what was really going on: (see Picture)<\/p>\n

<\/p>\n

\"\"<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

The air is just escaping directly to the outlet! Is there a way I can define within FLUENT the solid walls is cannot cross?<\/p>\n

<\/p>\n

If there are any suggestions for how to approach this problem, they would be most welcome. Many thanks!<\/p>\n

<\/p>\n
