<div dir="ltr">Hello all,<br><br>I'm having some problems in understanding the postprocessing sections of Gmsh's native file format (section 9 of the manual, <br><a href="http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC62">http://geuz.org/gmsh/doc/texinfo/gmsh-full.html#SEC62</a> ).<br>
<br>Consider this simple handmade example constituted by 6 nodes and 2 elements (see the attached file, or at the bottom of the<br>message).<br><br>The mesh sections are fine ($Nodes, $Elements). Now I want to add a $NodeData section. The example I made doesn't read if<br>
the $NodeData section is present ("Filling PViewDataGModel... Could not read data in msh file" - see the log attached).<br><br>Questions:<br><br>1- Do the string tags need to have a "" (or '') ?<br>
<br>2- According to the manual, <br><br>"By default the first string-tag is interpreted as the name of the post-processing view, and the second as the name of the<br>interpolation scheme."<br><br> Is this second tag mandatory? Where can I find more information about the interpolation schemes available?<br>
<br>3- What is the purpose of the real-tags in the postprocessing sections? <br><br><br>It seems the problem with my example is related to one or more of these issues, but I don't know what to do. I think a<br>simple example in the manual would make things much clearer.<br>
<br>Thanks for your help.<br><br>Paulo<br><br><br><br>$MeshFormat<br>2.0 0 8<br>$EndMeshFormat<br><br>$Nodes<br>6<br>1 0 0 0<br>2 1 0 0<br>3 1 1 0<br>4 0 1 0<br>5 2 0 0<br>6 2 1 0<br>$EndNodes<br><br>$Elements<br>2<br>1 3 0 1 2 3 4<br>
