Dear friends:

I want to use tecplot to plot my field contour, i use a quadratic triangular element, but i do not know what is the format for the quadratic triangular element. Tecplot provide the format for the linear element. Regards

yes, tecplot support just linear elements, but u convert a quad-triangle to four linear triangles then use tecplot (not a perfect solution, but what to do with this weakness of tecplot)

another solution is to use Paraview, it have support for quadratic elements as well (i'm not sure but i guess it split them in the same manner then visualize)

thank you very much, dear friends. so could you please help me with the format of the paraview. regards

is simple, should write a vtk file, for this read this document:

writing text vtk file is easy, but binart is bit more difficult, there is a smaple F90 code to write a binary VTK file by Renato Elias here:

hope this helps
