Which scripting part or Pyansys modules can I use to obtain results in the .avz format?

Naveen Kumar Begari

As we have ansys viewer to read .avz files to get visualisation in 3D.
Is their anything in pyansys same as ansys viewer or do we have any other extensions...?

Hi @Abel Ramos
But in PyDPF, 3D interactively outputs are unable to extract. If you have an overview on this.? Please share here

One option is to use PyWorkbench and PyMechanical to read the .rst file in Mechanical and then produce the .avz similar to this blog post:
https://developer.ansys.com/blog/create-report-saved-mechanical-session-mechdb-or-mechdat

Here is a blog post that describes how to do the first part manually:

@AKD-Scripting-Team , Do we have any exiting scripts to create a Mechanical project from an .rst as described above?

Hello, depending on your needs you can use pyDPF (or dpf in mechanical) to plot your results natively in a 3D visualization.

For example:

## AVZ export
import wbjn
import os
userdirectory = wbjn.ExecuteCommand(ExtAPI,'returnValue(GetUserFilesDirectory())')
results =ExtAPI.DataModel.GetObjectsByType(DataModelObjectCategory.Result)
#loop over the results
for result in results:
    result.Activate()
    mvm = ExtAPI.Graphics.ModelViewManager
    #avzFilename = r'D:\Temp\{}.avz'.format(result.Name)
    avzFilename = os.path.join(userdirectory,'{}.avz'.format(result.Name))
    mvm.Capture3DImage(avzFilename)

import wbjn
import os
def ExportAVZ(obj,export_directory):
   obj.Activate()
   # export_directory = wbjn.ExecuteCommand(ExtAPI,'returnValue(GetUserFilesDirectory())')
   filename = os.path.join(export_directory,'{}.avz'.format(obj.Name))
   ExtAPI.Graphics.Export3D(filename)
   return filename

Hi @Landon Mitchell Kanner , Thanks for response.

But, How can we do with PyAnsys using .rst files, instead of doing with IPython (Mechanical scripting).?

Attached is an in-work ACT extension that will work in Mechanical Stand Alone mode (not workbench). You can open Mechanical and load the app. There is a single button that will let you open a results file.

Upon selection it will launch MAPDL in batch in background, create a .cdb file from the .rst file, import that .cdb file into mechanical, create an analysis, and read in that results file for post processing

This is a work-in progress, in the sense it has limited testing, but the code is all open for review/modification to your own needs. It also does not imply this will be a native feature/function in the future, just a demonstration that such a workflow can be executed from the Mechanical API.

Here is code to leverage @Mike.Thompson 's solution to create an .avz from an .rst using pyMechanical:

RstPath = r'D:\Temp\project_Mech_Files\StaticStructural\file.rst'
library = r'C:\Users\lmkanner\Downloads\ResultsFileMechReader\ResultsFileMechReader'

from ansys.mechanical.core import App
import sys
import os
from ansys.mechanical.core import global_variables

outfolder = os.path.split(RstPath)[0]
app = App()
globals().update(global_variables(app))

sys.path.append(library)
sys.path.append(r'C:\Program Files\ANSYS Inc\v{}\aisol\DesignSpace\DSPages\Python'.format(app.version))


import RunAPDL
RunAPDL.Initialize(ExtAPI, Ansys)
SI, CdbPath = RunAPDL.GetCdbFileFromResultFile(RstPath)

import RunMech
RunMech.Initialize(ExtAPI, Ansys)
RunMech.ImportResultsToCurrentSession(CdbPath, RstPath, library)

def ExportAVZ(obj,export_directory):
   obj.Activate()
   # export_directory = wbjn.ExecuteCommand(ExtAPI,'returnValue(GetUserFilesDirectory())')
   filename = os.path.join(export_directory,'{}.avz'.format(obj.Name))
   ExtAPI.Graphics.Export3D(filename)
   return filename

results =ExtAPI.DataModel.GetObjectsByType(Ansys.Mechanical.DataModel.Enums.DataModelObjectCategory.Result)
for result in results:
   avz = ExportAVZ(result,outfolder)
