[Nektar-users] Different Element Types in a Mesh

Dear Dr. Comerford, For Nektar to solve a problem, do I have to generate the mesh with a single type of element? Because, when I try to convert a mesh (which is the combination of different type of elements quads+hexas+prisms) like the one below to an .xml file via MeshConvert, I'm getting such a warning message: *"Different Types of Elements in Same Composite".* I have to define the whole body as a single volume to solve my problem. Is there any way to define different types of elements in a single composite? Regards, Kamil
