+## Steps
+
+1. Set boundary conditions in and geometry in MetaVoxels
+2. for *t* timeSteps
+   1. Geometry conversion: solid (MetaVoxels) to LBM grid through convex hull of the nodes 
+      <img src="./concave_hull.png" width="70%" />
+   2. Run LBM for *n* timesteps
+   3. Get pressure values at geometry edges
+   4. Convert pressure to force on edge nodes (closest)
+   5. Run MetaVoxels simulation for *m* timesteps
