🔍 Description of the bug

"edge" option works the other way around for me. "OFF" shows the edges, "ON" hides them.

Also, I don't know where to ask it but using plnsol I can get a figure with a plot to open (although I have to issue the command twice for the figure with results to appear. It doesn't work like that with plvect, It open .png file for writing, doesn't close it until I plot something else and doesn't plot in the figure like it does for plnsol. I was only able to use plvect if I specify writing to file with mapdl.show()

🕵️ Steps To Reproduce

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl()

''' run any analysis with stress'''

mapdl.show(fname='PNG')
mapdl.plvect('s', mode='VECTOR', edge='ON')

mapdl.plvect('s', mode='VECTOR', edge='ON')

Hi @Artyom-K This is not a bug - it's a quirk of MAPDL that the 'edge' field of the plvect command is turning of/off the effect of the MAPDL /EDGE command. By default the /EDGE command does not show edges on a contour plot, so turning this off means to show the edges.

Also /SHOW redirecting to a file keeps the graphics in memory, so issuing another plot command (any plot) or /SHOW purges the memory and the file is writted to the storage drive.

Hi @mikerife

• Regarding /EDGE. I'm not sure if I should add something to the documentation? I guess adding /EDGE to the PLVECT command is not good idea. If there is no suggestion, we could close this issue.
• the issue with /SHOW should be fixed with Fix having to plot twice to get a file with size bigger than 3kb #2141

Thank you @Artyom-K for opening this issue.

@germa89 I'd leave the documentation alone as there are other examples of this that would need updated documentation too. Just on PLVECT there is the 'mode' field that interacts with the /DEVICE command.
