Issues with plotting recovery results using Gmsh

[Si1verBe11]

To see the results of the recovery analysis, I run prevabs -i mh104 -h -e on the ex_airfoil_r example folder and prevabs -i mh104.xml -d -e -v.
This resulted in the following situation when Gmsh was run.

1. First of all, it looks like the category for postprocessing is incorrect: there's a category despite no displacement results, and the subitems have stress values in them.

Well, I can use the 27 stress strain values anyway, but I have an additional issue with them.

2. As shown in the figure above, it incorrectly recognizes the maximum value of strain.
   Checking the values in the ELE file, the maximum strain value is about 4.82e-8.
   I manually put that value in the maximum value position, and the results seem to be plotted correctly.
   

3. The last question is the most important one.
   Issues like these are just inconveniences, but I can use them as it is.
   But, is there no way to plot stress/strain separately for each material in Gmsh?

Why do you need stress/strain for each material? If you want to access the failure, VABS failure analysis might be easier for you to use.

Thanks Prof.Yu, I will utilize that!
