Feature/Boundary conditions plotting

[germa89]

Currently there is no standard way to plot forces, displacement constraints, etc.

In APDL, the displacements are plotted like this:

Ideally we should have a way to plot the boundary conditions.

This might be a long (and difficult) one.

Hi @germa89,

Have you tried to use https://mapdldocs.pyansys.com/mapdl_commands/graphics/_autosummary/ansys.mapdl.core.Mapdl.pbc.html?highlight=mapdl%20pbc#ansys.mapdl.core.Mapdl.pbc ?

Mapdl.pbc(item='', key='', min_='', max_='', abs_='', **kwargs) - Shows boundary condition (BC) symbols and values on displays. [APDL Command: /PBC].

Thank you!

Hi @RomanIlchenko1308

The command you mentioned only works in MAPDL GUI. I tried in PyMAPDL and it does nothing. Maybe I'm missing something.

Eplot

Nplot

Code to replicate my test.

from ansys.mapdl.core import launch_mapdl
from ansys.mapdl.core import examples

mapdl = launch_mapdl(start_instance=True, port=50054)
mapdl.clear()
example = examples.vmfiles['vm101']
print(example)
mapdl.input(example)

mapdl.pbc('TEMP', 1)
mapdl.eplot()
mapdl.nplot() 

mapdl.exit()

This may not be so difficult.

Ideally we should have a way to plot the boundary conditions.

We just need a way to rapidly get the DOF constraints in a node-wise array. We get similar data from our get_array method, which used *VGET under the hood.

I don't see this information in https://www.mm.bme.hu/~gyebro/files/ans_help_v182/ans_cmd/Hlp_C_VGET_st.html, but there must be another way to get it efficiently.

Ping Mohamed K., he'll likely know.
