Hi! I have a MSH file for a mesh of one quadrangle and four associated scalar field node values. Looking at the GMSH visualization, it uses two triangles to define the function shape inside the quadrangle, and it seems to use P1 shape functions within each triangle.
Is it possible to have GMSH not use any triangles for the visualization, but instead assume that the scalar field should be represented with Q1 shape functions inside the quadrangle? Here is the MSH file, and the screenshot is attached: $MeshFormat 2.2 0 8 $EndMeshFormat $Nodes 4 1 0.0 0.0 0.0 2 1.0 0.0 0.0 3 1.0 1.0 0.0 4 0.0 1.0 0.0 $EndNodes $Elements 1 1 3 2 99 2 1 2 3 4 $EndElements $NodeData 1 "A scalar view" 1 0.0 3 0 1 4 1 0.0 2 1.0 3 0.0 4 0.0 $EndNodeData Best regards and thanks, Torquil Sørensen
