nastran_to_vtk skipping pressure on ['CHEXA']

[guotao1415]

from pyNastran.converters.nastran.nastran_to_vtk import nastran_to_vtk

filename = r'D:\WORK\op2_to_vtk\models\unit\pload4\chexa'

bdf_filename = filename+'.bdf'
op2_filename = filename+'.op2'
vtk_filename = filename+'.vtu'

nastran_to_vtk(bdf_filename, op2_filename, vtk_filename)

I'm sorry to bother you again, but I output the following warning while using the above code. I tried other files in the models folder and received a similar warning. Why is this? Shouldn't it be because they don't support these entries?

If possible, is there any bdf and op2 file in your warehouse that can be directly used with nastran_to_vtk? I have used several in your models folder, but there will be warnings and vtu files will lose some result information such as stress and strain.

The converter uses the same reader as the gui, so it has the same (or more) limitations. I can’t apply a surface pressure to a solid element and have it only color the face, so there is a warning.

What results that show up in the gui are missing? Most of the results from the op2 are not supported in the gui, but if there’s a specific one, I can look at it.

added a log_level' flag (options are debug, info, warning, error (default=='error).

I think i addressed the issue. Not sure about the stress comment, but reopen if you have a model.
