Hi!<br class="">
<br class="">
I have a MSH file for a mesh of one quadrangle and four
associated<br class="">
scalar field node values. Looking at the GMSH visualization, it
uses two<br class="">
triangles to define the function shape inside the quadrangle,
and it<br class="">
seems to use P1 shape functions within each triangle.<br

<br class="">
Is it possible to have GMSH not use any triangles for the
visualization,<br class="">
but instead assume that the scalar field should be represented
with Q1<br class="">
shape functions inside the quadrangle?<br class="">

<div class="">Yes: select "Adapt visualization grid" in the
options of the view. (Set the target error to a negative number
to force subdivisions all the way to the maximum recursion

Thanks! This is much easier than for me to interpolate my FEM
solutions onto a finer mesh before visualization. It even looks as
if the GMSH recursive adaptation procedure converges towards
something that looks like Q1 shape functions...<br>
<br>
Best regards and thanks,<br>
