Hi all,

I have three regions in my block mesh
1. Region bounded by blockmesh
2. Region named box - searchablebox
3. A ship as an stl file.

When I keep the locationinmesh point in the 1.region both 2 and 3 goes off.

When I keep the locationinmesh point in the 2.region both 1 and 3 goes off.

When I keep the locationinmesh point in the 3.region both 1 and 2 goes off.

But I want a mesh with both Region 1 and Region 2 and the ship should be removed, so that I can analyse the flow of water around the ship.

And I am not able to keep two locationinmesh points.

How to achieve this.?

Hello senthilathiban,

- Do the both Mesh-regions you want to keep have a contact/interface with each other?

If not, the walking-on-Mesh step during snappyHexMesh will not discover both!

- blockMesh must include all regions! The parts outside the Mesh generated by blockMesh will not be recognized by snappyHexMesh!

- Did you defined the regionProperties dictionary in constant? I belive you must! see tutorial multiRegionHeater for more informations.
