Hi all,

I have written an FEM - Programm for bilinear quadrilateral Elements for structual analysis. As a preprocessor I am using GMSH, the processor is written in Matlab and I’d like to use ParaView as the postprocessor. Everything is working fine so far, but the last two days I tried getting to visualize the element-stress to work. The output of my calculated stress is at the gauss points. I searched for similar Problems, but I haven’t found a solution. I can generate the quadrature points in ParaView but I can’t get the according data visualized. So far I have put the stress data as FieldData.

My question is: Is it possible to assign my stress-data to the gauss points ( I have the stress data at each gauss point and in each direction)?

The arrachment is a 2x2 ( = 4 ) elemental quboid which is loadad by an lineload on the right side.

Thank you so much in advance!
