I would not Auto-stabilize it. I would add edge supports and/or spring lateral stiffness (analogous to friction).

when using auto stabilizing in the x and y direction, wont that affect the lateral loads and over turning uplift moment

I created a mat under the wall core and opened it in concepts. I also have defined the soil properties under the footings. But now when I run it this error pops up. Do I need the somehow fix the Mat? Also is there any reference/ tutorials on modeling with uplift in RAM concepts.

Thanks

Model a rectangular mat footing in the Modeler on the 2nd level plan (Layout - Foundations - Mat...). Make sure the perimeter of the mat encompasses all walls that need to be supported. Add a concrete deck/slab to the whole mat. Then rerun the analysis and export the Mat to Concept.
