Hi,

I am trying to create a user butter in order to accelerate my post-processing in Ansys Mechanical.

My dream when I click on the button is :

1- Create one folder with : total displacement ; 3 directional displacements ; VM stress 

2- Create one folder for a specific name selection with : total displacement ; 3 directional displacements ; VM stress 

3- Export these results (min/max values) in a csv file.

I found this command for the total displacement : ExtAPI.DataModel.Project.Model.Analyses[0].Solution.AddTotalDeformation()

But I don't know how to fin other commands for directionnal displacements, VM stress, for creating folders, exports results ...

Thanks you for your help :)

Hi

You can use the record in the mechanical scripting console, and add the directional deformation , etc., and you will see the commands (e.g., AddDirectionalDeformation(), AddEquivalentStress(), etc.)

On how to het the max/min from these results, one can get that by:

equivalent_stress = ExtAPI.DataModel.Project.Model.Analyses[0].Solution.AddEquivalentStress()

MaxVMSt=equivalent_stress.Maximum

Then export MaxVMSt to a csv file. Search the internet how to export there are many posts on that, e.g., : 

https://www.programiz.com/python-programming/writing-csv-files

Finally group is a bit hard, but not really needed in order to create the results, extract max/min and export these values.

If needed folders/groups look at the below link for an example that adds these results and puts them into a folder.

All the best

Hi Erik,

Thanks a lot for your answer!

I try with a simple code, and it works!

I have two more questions:

1- Is there any documentation to easily get these informations ?

2- I try to create a displacement result for a named selection, but the record is incomplet I guess. I get the command bellow where the scoping method is "named selection", but I don't know how to affect a named selection.

total_deformation_45 = solution.AddTotalDeformation()
total_deformation_45.ScopingMethod = GeometryDefineByType.Component

Thanks a lot,

Jean

nb : I did not try the export for now.

 

Code example:

#----------------------------------------------------------------
solution = ExtAPI.DataModel.Project.Model.Analyses[0].Solution
#----------------------------------------------------------------

 

#----------------------------------------------------------------
resgr=[]

# Déplacement selon x, y, z, total
directional_deformation_global_x = solution.AddDirectionalDeformation()
directional_deformation_global_x.NormalOrientation = NormalOrientationType.XAxis
directional_deformation_global_y = solution.AddDirectionalDeformation()
directional_deformation_global_y.NormalOrientation = NormalOrientationType.XAxis
directional_deformation_global_z = solution.AddDirectionalDeformation()
directional_deformation_global_z.NormalOrientation = NormalOrientationType.XAxis
total_deformation_global = solution.AddTotalDeformation()

# Contraintes equivalentes Von Mises
equivalent_stress_global = solution.AddEquivalentStress()

resgr.append(directional_deformation_global_x)
resgr.append(directional_deformation_global_y)
resgr.append(directional_deformation_global_z)
resgr.append(total_deformation_global)
resgr.append(equivalent_stress_global)

dossier_global = ExtAPI.DataModel.Tree.Group(resgr)
dossier_global.Name = "Global"

Hi

1. See this link: https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/prod_page.html?pn=Customization%20Suite&prodver=22.2&lang=en
2. See the link here on how to scope results to named selection (if this is not what you want search in the dev. forum): https://discuss.ansys.com/discussion/909/insert-total-deformation-result-in-modal-analysis-scoped-to-a-named-selection-and-define-maximum-and
