Plotting Heat Flux

[VHB4910]

I am running a steady state heat equation problem in PyMAPDL. The solution (temperature) field is plotted below:

I now want to plot the heat flux/temperature gradients using PLESOL mapdl.plesol("TF","X") which gives me this as output:

However, when I open the gui mapdl.open_gui() and use PLESOL,TF,X I get this as the output:

What could be the issue? I also tried to :
mapdl.etable("HFX","TF","X") mapdl.get_array("ETAB", "HFX")

but I get an array of 0s as output.

Interesting. I would make sure you have selected everything before plotting:

mapdl.allsel()
mapdl.plesol("TF","X")

If that not works, I would open an issue and attach the minimum code that can reproduce that issue.

Yup, this worked. Thanks @germa89

@germa89 @VHB4910
Germa89 has it right - that 'empty' plot looks like what happens when just the exterior nodes are selected and 'full' graphics is active, which is the default for mapdl batch and aaS (run type used by pymapdl). You could issue the allsel prior to the plot. Or switch to 'power' graphics prior to the plot.

'power' graphics are the default when running mapdl interactively.

You're right @mikerife Thanks for the suggestion.
