As far my understanding, formulation of custom elements is needed. For example, Spectral elements method requires very high order element.
My question is, do people do this by hand or use any software tool?
Thanks.
Thanks Mohammed abed Alruda . Can you please specify any specific software? Or available existing code?
From what I have seen, most people use Abaqus UEL, VUEL subroutines to do this if its not available in the software itself. So you only implement the element formulation, rest is taken care by the software.
Also many people use open source codes like dealii, mfem, feap, etc. to do this.
read these articles regarding the XFEM in 3D can use ABAQUS software there are many studies in google scholar just search there

Thanks Mohammed abed Alruda and Akhilesh Pedgaonkar . I have created a software that formulates Shape functions for higher order Hexahedron (Lagrangian and serendipity), Tetrahedron and Custom element. I am sharing some screenshot of this software that is used to build a 22 node brick element.
