Splitting host rock into sub-zones using mesh intrusions — dynamic workflow?

Hey community! Question about dynamic geological model using closed meshes as dividers

I'm trying to build a geological model in Leapfrog Geo 2025.3 with the following setup:

  • 1 envelope mesh (HOST ROCK) — the main host rock
  • 4 tabular body meshes (B0, B1, B2, B3) — geological dykes that crosscut the HOST ROCK
  • My goal: HOST ROCK should be divided into 5 separate lithologies (A0 to A4) by the 4 B bodies, and the model should update dynamically when the B meshes are revised by the geology team

So far, I've successfully modeled the B bodies as Intrusions from mesh inside a Geological Model and they correctly cut the HOST ROCK. However, I cannot get the HOST ROCK to split into the 5 zones (A0 through A4) as separate named lithologies in a dynamic way.

My limitation: I only have closed mesh solids — no point data, no surfaces and no drillhole data.

I'm attaching one image showing the current state — you can see the B bodies (dykes) cutting the HOST ROCK (As), but all as separate meshes with no drillhole data

Any ideas are welcome. Thanks in advance! 🙌
