Triangular Mesh Plot
 

Hello,

I am graduate student. In my thesis, I am interested in Finite Element Analysis of arbitrary cross section beams. In this regard, I write FEM codes in Fortran
language. I have node coordinates data and element connectivity data. How do I show this meshplot in paraview or gnuplot or VisIt? Would you please help me in this matter?

Thanking you in advance.
