Hi. This is my first post, so sorry if this question as already answered, but I've searched in the list and I didn't found anything useful for me.
I need to create a mesh in a box with different dimensions at each side. I first create a mesh, and then I create a box of specified size at each side. And I want tetrahedral elements. I do in this way: === Mesh xMesh; MeshTools::Generation::build_cube(xMesh, nx, ny, nz, 0, xLength, 0, yLength, 0, zLength, TET4); === In my problem I must set values at specified points inside the domain. Infact, I want that the user specify initial conditions at arbitrary coordinates inside the domain, and then interpolate these data in all domain itself. These points are generic, so there are not original grid points. For example the user can specify different points with different values inside the same mesh element (in theory the user does know nothing about the mesh). So, I must add these nodes manually to the mesh to make it coherent with initial conditions. I've seen in the class documentation the add_node in the member functions of Mesh class, but I've also seen add_point and add_element, so I don't know how to use it, and I didn't see an example that shows how insert a node manually inside the domain. What I must to do, if I want to modify the mesh and adding nodes (with consequent re-meshing) at specific coordinates?
