So by way of experiment here is the concrete raft sans reinforcement (I haven't worked out how to make Sketchup successfully export the stl file for that without breaking it). I drew it in Sketchup as a 6m x 4m x 300mm slab with a 5.4m x 3.4m x 200mm void underneath, exported it as an STL:



Then imported that into Z88Aurora and meshed it:



Then applied material info and fixed constraints at 3 corners and a 100N upward load at the 4th corner (nearest to camera), run the solver and get this:



which suggests a 7mm upward displacement, which intuitively feels very large for 100N load....

more experimentation to come :)

fun this learning curve tho...
