Hi @akriger,
You’re welcome - and I checked your project setup.
The main blocker is not the solver itself, but the geometry/setup: the model is still in a non-runnable state, with the wall condition applied to 3,668 separate faces. That level of fragmentation often goes together with the kind of CAD/material issues you are seeing. The best next step is to simplify the CAD in CAD Edit and make sure you are simulating only the fluid region by using a flow volume extraction, not the solid buildings as simulation volume (to your question - yes! you should absolutely delete the solid geometries, and you can do it in CAD Edit).
I also noticed there are currently no result controls defined, so even once the mesh runs, you will not get structured outputs for GIS unless you add probes/surfaces/field calculations first.
So I would focus on these in order:
- clean/simplify the geometry,
- extract the fluid volume,
- reduce boundary assignments to grouped faces,
- add result controls for the 1.7 m data you want.
Cheers,
Igor
