Julia integration is broken

[germa89]

Importing PyMAPDL is broken. The following code crashes the terminal:

using PyCall
pymapdl = pyimport("ansys.mapdl.core")

It seems this is due to the helper objects we create in plotting.py.

pymapdl/src/ansys/mapdl/core/plotting.py

Lines 74 to 147 in 22b85be

	TEMP = pv.Sphere(center=(0, 0, 0), radius=0.5)
	UX = pv.Arrow(
	start=(-1, 0, 0),
	direction=(1, 0, 0),
	tip_length=1,
	tip_radius=0.5,
	scale=1.0,
	)
	UY = pv.Arrow(
	start=(0, -1, 0),
	direction=(0, 1, 0),

	tip_radius=0.5,
	scale=1.0,
	)
	UZ = pv.Arrow(
	start=(0, 0, -1),
	direction=(0, 0, 1),

	tip_radius=0.5,

	FY = pv.Arrow(

	tip_length=0.5,
	tip_radius=0.25,
	scale=1.0,
	)
	def get_VOLT():
	model_a = pv.Cylinder(
	center=(0, 0, 0), direction=(1, 0, 0), radius=0.2, height=2
	).triangulate()
	model_b = pv.Cylinder(
	center=(0, 0, 0), direction=(0, 1, 0), radius=0.2, height=2
	).triangulate()
	model_c = pv.Cylinder(
	center=(0, 0, 0), direction=(0, 0, 1), radius=0.2, height=2
	).triangulate()
	result = model_a.merge(model_b).triangulate()
	result = result.merge(model_c)
	result.rotate_z(45.0, inplace=True)
	result.rotate_vector(
	vector=(1, -1, 0), angle=-45, point=(0, 0, 0), inplace=True
	)
	return result
	VOLT = get_VOLT()
	HEAT = pv.Cube(center=(0, 0, 0), x_length=1.0, y_length=1.0, z_length=1.0)

One way to mitigate that, is making those objects attributes of a new class:

# Symbols for constrains
class DefaultSymbol:

    def __init__(self):
        self.TEMP = pv.Sphere(center=(0, 0, 0), radius=0.5)
        ....

Temporary fix

There are two temporary solutions until I have time to implement the above change.

• Uninstall pyvista from the local python environment (in PyCall.python)
• If PyMAPDL is installed in editable you can replace the following line 70:
  

  pymapdl/src/ansys/mapdl/core/plotting.py

  Line 70 in 22b85be

  if _HAS_PYVISTA:

  
  by:

if _HAS_PYVISTA and False:
    import pyvista as pv

But this can create issues later.
