Reading ANSYS APDL (RST) results in Paraview

Hi Everyone,

Is there any way to read ANSYS APDL (RST) result in Paraview?
I searched the forum and found some posts but none of them were helpful.

Thank you in advance.

Hi @Mike_Richards ,

There is no such reader in ParaView, you may need to convert your data to another format.

Best,

Hi,

You may be able to convert .rst file to .vtk or .vtu file using PyMAPDL.

The script for the conversion is shown below.

from ansys.mapdl import reader as pymapdl_reader

result = pymapdl_reader.read_binary('file.rst')
print(result)

result.save_as_vtk('file.vtu', [0])

The arguments of save_as_vtk function are explained in the following link:

                    STRESS_TYPES,
                    show_displacement,
                    displacement_factor,
                    node_components,
                    element_components,
                    sel_type_all,
                    treat_nan_as_zero=treat_nan_as_zero,
                    **kwargs,
                )
            
            
def save_as_vtk(
                self, filename, rsets=None, result_types=["ENS"], progress_bar=True
            ):
                """Writes results to a vtk readable file.
            
            
    Nodal results will always be written.
            
            
    The file extension will select the type of writer to use.
                ``'.vtk'`` will use the legacy writer, while ``'.vtu'`` will
                select the VTK XML writer.

Hi All,
I know there has been a bit of time that has past, but there is another way to retrieve the data if you have access to EnSight. Select the part(s) you would like to export and select File->export->Geometric Entities. You can then save it as a case file, which ParaView will be able to open.

Of course, if you have no access to EnSight, using the method above would be the only option that I know of.
