Hi,
I'm working on data center CFD analyses. I noticed that mesh elements near the racks is very small due to the rack thickness. So I planned to create zerothickness wall for rack geometry so that I can create coarse mesh. is there any option other than toposet (split mesh) to create zero thickness wall.
In my 2nd query, I need to add some momentum source. I noticed that toposet again can be used to create the cellzone where I can add momentum source but I'm concerned whether I need to shift to CHT..foams or I can still use BuoyantBoussinesq...foam.

Dear Dr. Fazil,
The method I usually go with to create zero thickness walls is to extract/create face zones using topoSet utility and then use those face zones to create walls using creatBaffles utility.

Dear Divyesh,
Thank you. But I need to stl files, as team members find little difficult to create seperate geometry 'toposet' for one component alone. So I thought of creating stl files and use that particular stl file for toposet and others for snappyhex

Dear Ashley,
Thank you so much, I'm also working on the same strategy now.
Is it feasible to use 'stl' files to create facezone?

Dear Dr. Fazil,
I haven't used toposet yet using stl files. But I found a forum post, linked below, that you might find helpful.
