I say manually because I needed to implement the substitution of the nodes myself and I couldn't do it using Gmsh using removeDuplicate and so on (i.e., I didn't know how to do it). > After reading the manual, tutorials and mailing list, the only approached that worked was the next one: having a single closed shell joining 'manually' the nodes in the boundary. ![]() > 5) Exporting the mesh to Abaqus/LS-Dyna (whatever software) > 3) Create a volume using a surface loop on both surfaces > 2) Create a 2 discrete surfaces giving the node coordinates and the connectivity of the triangles > 1) Read point clouds and triangulate using Delaunay (scipy.spatial) > My final goal is to create a volume mesh enclosed by two discrete STL surfaces (given by a point cloud). > first of all, thank you for sharing the software with us!
