I made a simple cube in design moduler and saved it.
when taking mesh it starts and goes away automatically and then a x mark in mesh. error is "Unable to attach to geometry file" I tried cad configuration and also even reinstalled ansys still the issue is there...

Attached is a photo of this. I read somewhere that if your "SYS.mechdb" is showing a file size of 20kB (which mine is) then that means it's corrupted ( http://xansys.org/forum/viewtopic.php?p=91606 ), and found step by step how to reload it ( http://www.padtinc.com/blog/thefocu...bletorecover )... But I just tried that and I got the "Failed to load legacy database" error in the Ansys main window. Also I would rather PREVENT the corruption, especially when using built in DesignModeler!! For the record: I am not getting corrupted databases after "hardclosing" Ansys. It is within the same Ansys session, from when I create the geometry in DesignModeler, open the mechanical Model to perform meshing and loads, then closing Model, and opening it again.

Hi rbgamblin,
Try to use a simple model and see if its working. Did you change location from default when you where installing Ansys? I think its not able to locate your model and thats why giving error. Try reinstalling? Cheers KAPI

I've created my Geometry by scripting in DesignModeler. When I run the Script, DesignModeler opens and the geometry creates. When I close DesignModeler it shows the green hook after Geometry in my Workbench. So it should have created the Geometry correctly. When I now want to open Mechanical it shows me the following Error: Code:
CommandFailedException: Geometry must be attached before branches can be created. In file "Z:\Diplomarbeit_HTW\MATLAB\einfache_Zahngeometrie\Running_Script.wbjn", line 2944 Edit: I just found this Code in the "DSGeometryScript.js: Code:

I also faced same problems. But ansys workbench accepts format iges only..
so just save ur model in iges format and then import it will definetely work.

Hi Guys,
I suggest reinstalling and checking if it is working! If it is still not working, I reckon you should contact Customer support cuz it could be a bug. Cheers KAPI

ok, I figured out that the problem isn't the Mechanical .. I've entered a new Material (Engineering Data) by scripting.
When I use a given material (Engineering Data) everything works fine .. so I have to find the failure in my Engineering Data  script. There has to be a mistake or something missing ..

Hi Max,
Share your script so that we can figure out the issue. Cheers KAPI

Hi Max,
Add below code with your previous code and see if it works! Code:
# encoding: utf8 SetScriptVersion(Version="15.0") template1 = GetTemplate(TemplateName="Engineering Data") system1 = template1.CreateSystem() EngineeringData1 = system1.GetContainer(ComponentName="Engineering Data") EngineeringData1.Edit() StrucSteel = EngineeringData1.GetMaterial(Name="Structural Steel") StrucSteel.Delete() NewMaterial_31CrMoV9 = EngineeringData1.CreateMaterial(Name="31CrMoV9") .... ... ...

Hi Manan,
Can I suggest you to start another thread with your question. Posting random question in random thread is not very useful. Start a new thread and ask your question giving all the details you have so everyone can help you in your thesis! Cheers KAPI

I now tried this: 1. open ANSYS Workbench > static structural > engineering data > library > new material 2. enter properties and save it (D:/Temp/31CrMoV9 3. close ANSYS and open again 4. ANSYS Workbench > static structural > engineering data > library > bottom "..." = add an existing data source from file" > chose this file which was generated seconds before 5. Error (I've added a screenshot below) Do you have a suggestion? Best regards Max

ok, I figured that problem out .. this one is working now .. but after several testing I realized, that I get a blue question mark infront of the Geometry in ANSYS Mechanical (from Workbench) even if I change the material to a listed material like Copper Alloy. I can change material manually (following several different tutorials) and get the same problem. Does anybody had a problem like this before or do I have to save the changed material again in some different way?

Hi Max,
One of the reason for the blue question mark could be that you have not defined the full property of material. To choose new Material from the data bank use this code. Code:
#Material Selection #Accesing the Engineering data and modifying the Material engineeringData1 = system1.GetContainer(ComponentName="Engineering Data") matl1 = engineeringData1.GetMaterial(Name="Structural Steel") matl1.Delete() favorites1 = EngData.LoadFavoriteItems() library2 = EngData.OpenLibrary( Name="General Materials", Source="General_Materials.xml") matl2 = engineeringData1.ImportMaterial( Name="Aluminum Alloy", Source="General_Materials.xml") #End of Material Selection Cheers KAPI
