Hello everyone,

I am trying to set up an FSI simulation where I would like to use 2nd or higher-order elements for the structural mesh and 1-order elements for the fluid mesh. It is important to note that the structure and fluid domain are modeled together in the same mesh.

I am currently using 1st order elements for fluid and solid regions. As per my understanding of gmsh, we can generate a mesh with higher-order elements, but when I use that functionality, higher-order elements are used for the entire mesh.

Is there a way to set a different order of elements in different volumes on gmsh?
