from ansys.mechanical.core import App
app = App(globals=globals(), log_level="DEBUG")
print(app)

app.helpers.import_geometry(<path>)
app.helpers.print_tree()
app.helpers.export_image(app.Model.Geometry, "geometry.png")
app.helpers.setup_graphics("front")
app.helpers.export_image(app.Model.Geometry, "geometry_front.png")

modal = Model.AddModalAnalysis()
solution = modal.Solution
total_deformation = solution.AddTotalDeformation()
Model.Solve()
app.helpers.print_tree()

app.helpers.export_animation(total_deformation, "deformation.gif")
app.close()
