Problem run DEM 3D

[LVilla96]

GOOD DAY!!

I have a problem with a DEM 3d simulation:

The error window describes the following error: "Traceback (most recent call last): File "MainKratos.py", line 31, in DEMAnalysisStageWithFlush(global_model, parameters).Run() File "MainKratos.py", line 12, in init super(DEMAnalysisStageWithFlush, self).init(model, project_parameters) File "/home/engineer-user/.local/lib/python3.8/site-packages/KratosMultiphysics/DEMApplication/DEM_analysis_stage.py", line 72, in init self.DEM_parameters.ValidateAndAssignDefaults(default_input_parameters) RuntimeError: Error: ** The item with name :"ElementType" does not have the same type as the corresponding one in the default values

I got the same problem.

Hello @LVilla96 and @MatiasVenegas . Thanks for reporting, Can you provide more details on how did you generate the case and which version of Kratos you used? For the GUI, did you use the Internet Retrieve within GiD? If not, was it a pre-compiled release? Or did you compile Kratos by yourself?

[jginternational]

Hi @LVilla96 Could you attach a zip containing the model?

[LVilla96]

@jginternational It is a cone created to test the operation of 3D with DEM. It doesn't seem to work https://drive.google.com/drive/folders/1Iqt5X80ygXpHqTHNwR3DifJoACg5vxZ-?usp=sharing

[LVilla96]

@maceligueta Is Kratos Multiphysics 9.1.3. No, i didn't use internet retrieve. I compiled Kratos by myself.

[maceligueta]

Ok, I will take a look this morning.

[maceligueta]

Ok, in the ProjectParametersDEM.json file, instead of "ElementType" : [], if shoud read "ElementType" : "SphericPartDEMElement3D", With this change, the case starts running. Now we have to figure out why the ElementType ended up being [] Any idea, @jginternational ?

[maceligueta]

@jginternational , could you take a look at this?

[jginternational]

Hi @LVilla96

The model you've attached was created using the problemtype (User interface) version 9.0.1, not the one in the current master. The master branch version changed like a couple months ago, and the function that assigns the element type in the DEM project parameters was changed 9 months ago.

Please check if you are using the master branch (git status) and latest version (git pull) , because I can not reproduce this behaviour now
