Unable to attach to geometry file

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...

I uninstalled then reinstalled ANSYS and now it works.
There are a few known issues when installing ANSYS on Windows 7. The problem seemed to be that ANSYS was installed in C:\Users\username instead of Program Files.

To avoid this problem, you have to turn off User Account Control and IPv6 before installing ANSYS.

Thanks again Ali for your help

I am having the same problem with a geometry I created in DM. Funny thing is, I was just running a very similar geometry in Fluent through ANSYS WorkBench and it meshed and solved just fine. I am running on Windows 7. I checked and ANSYS is installed in Program Files.

Same problem, different user

It gives me this issue if I close the "Model" and have to open it back up again (which is always, because I have to tweak stuff).

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/the-focu...ble-to-recover )... 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 re-installing?

Cheers

Hi,

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

Do I have to export the DesignModeler Geometry as .iges or something like this first?

Edit: I just found this Code in the "DSGeometryScript.js:

Code:

var pmdlg;



var kUpdateFromCAD                              = 0;

var kUpdateAllCADParameters             = 1;

var kUpdateChangedCADParameters = 2;



var bIgnoreToolbarUpdate = false;

var errorAttachCallback;

var warningAttachCallback;



/* START OF ATTACH METHODS */

// this funtion is sitting here just because other funtions here using it, already moved to C++: Jay 06/03/07

function progressAttachPane (filename, caption)

{

    pmdlg = CreateActiveXObject (str_WBHTMLDialogProgId);

    var xf = CreateActiveXObject(str_DlgArgsProgId);

    xf ("wb") = wb;

    xf ("dlg") = pmdlg;

    xf ("WBScript") = WBScript;

      var coordinates= wb.GetNthFileName(str_SaveProgressWndCoord, "DSApplet");

    pmdlg.InitialWindowPosition = coordinates;

    pmdlg.DoDialog (wb.hWnd, filename, xf, true, 400, 150, 0, caption, true);

    pmdlg.SolutionDlg = true;

}



function SpecificAttach (PIName, fName, existingBranch)

{



    try

    {

        if(typeof(existingBranch) == "undefined")

        {

            g_UIHandler.GeometryHandler.SpecificAttach0(PIName, fName);

            RefreshMeshingOptionsPane();

        }

        else

            g_UIHandler.GeometryHandler.SpecificAttach(PIName, fName, existingBranch);

    }

    catch(e)

    {

        return e.number;

    }

    return 0;

}



function doPlugInEasyAttach()

{

    SpecificAttach("", "");

}



function FileEasyAttach(fName)

{

    SpecificAttach(fName, "");

}



function doAttachAssembly()

{

    WBScript.Out (localString("ID_DoAttachAssemblyMessage"), true );

}

/* END OF ATTACH METHODS */

.. but I actuall don't know how to use it .. I think it should work with only this function:

Code:

function FileEasyAttach(fName)

{

    SpecificAttach(fName, "");

}

but maybe this is jut too easy ;)

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, thanks for reply. This didn't solve the problem either.

Hi Guys,

I suggest re-installing 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

Any one else have module for learning ansys ,I want it bcoz I m student of master of science and wan a use it in my proj.so

I coulnd't find a mistake in my code .. I think there is some additional information missing!?

I want to analysis of wind turbine by CFD if u have any program for understand it then pls send me on :Mananpatel1991@yahoo.com

Hi KAPI,

... can you find any missing information or invalid input data or something else? (my Code is two entries above)

Best regards,
Max

Hi Max,

Add below code with your previous code and see if it works!

Code:

# encoding: utf-8

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")

....

...

...

Cheers
KAPI

Kapi have you any code which can help me to make a thermal analysis of engine fins or heat exchanger or any elements ,for master thesis

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

This doesn't work either.

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

see if you are getting same problem if you change your material!

Cheers
