Hi everyone,

I am using Clever in 3D Slicer for generating tetrahedral mesh. The mesh generated is by default based on the 4-node linear tetrahedral element (C3D4). How can I change the element type to the 10-node quadratic tetrahedral element (C3D10)?

Thanks,
Zahra

Higher order elements aren't supported in Cleaver at this time. However, the C3D4 mesh can be converted to C3D10 by adding nodes at the midpoints of the edges. Other software can to this, but FEBio studio (https://github.com/febiosoftware/FEBioStudio) is one that is geared toward biomachanics simulation, and is also produced at SCI

Thanks @jessdtate for your reply.

Yes, adding midpoints to C3D4 elements is the easiest way, but it's not optimized and efficient computationally. Because however we will have C3D10 (that means higher numbers of nodes/DOFs), still the mesh generation is based on the linear elements that need to be finer to fit the curved boundary surfaces.

I will look at other alternatives, such as Gmsh and FEBio that you mentioned.

Thanks,
Zahra
