Hello! I am a university student in Korea. I intended to learn OpenFoam, but I am currently using Baram CFD. Baram CFD has a tool similar to SnappyHexMesh. However, I cannot generate the small prism layer needed for y+1, and it seems to fail mesh quality tests unless the geometry is simple. (Of course, I might have adjusted the options incorrectly, but that was the case at least when I applicate the tutorial.) References regarding Basic Pinner mention constructing a 3D mesh similar to the photo below (they use the HexPress utility). Are there any free or open-source tools capable of constructing a 3D mesh like this? https://cdn.discordapp.com/attachments/796072568385568808/1538065715595051048/mesh4.png?ex=6a8152d2&is=6a800152&hm=8a1218db60b6fbed65107586628e6217010405b1f95323115e5c575c0b2e89f6& https://cdn.discordapp.com/attachments/796072568385568808/1538065716207554650/mesh2.png?ex=6a8152d2&is=6a800152&hm=8d66b957838f20349acff4f1d4ebb8510e22df2ae23830f35c217ff04df8de69&
