<div dir="ltr"><div>Dear gmshers,</div><div> </div><div>attached you will find two contour plots from a scalar field. The first one (contour1.png) was made with gmsh using $NodeData feature, without using any extra $InterpolationScheme rule info. The second one (contour2.png) was made using another post-processing software with the same nodal values. This second image is the right represantion of the contour for the scalar field.</div>
<div> </div><div>As you notice, gmsh interpolate the nodal values with a "wrong" way. Ignoring the color mapping, how i can use the $InterpolationScheme feature in .msh format in order to get the right distribution inside the elements from the corresponding nodal values?</div>
