Dear Professors Geuzaine and Remacle
First of all, I would like to say thank you for providing a
wonderful software, Gmsh, to public.
I started to use Gmsh last week, and I am now trying to draw iso-
value map of deformed solids.
The deformation is analized by FEM develped by myself and Gmsh is
used as a post-processer.
First, to check the grammer of file format, I draw a iso-value
contour with one quadrangle element.
Please have a look at some results shown in the attached file.
Node value is given such that 1 for a node and 0 for others.
The node possessing a value of 1 is changed.
The symmetric figures were expected to be drawn, but the results
were not and have apparent directionality.
I could not find mistake in the input file, which is also copied in
the attached file.
If you could give any comment, it would help me a lot.
Hello,
By default, GMSH represents a quad as 2 triangles, so this is correct
in this sense. Yet, you
should be able to refine this view, using Options->View[0]-
