Using iLogic for Idealization of Shell Elements

[Anonymous]

Hi, 

I want to use iLogic to create a Shell Element Idealization and can't find a way to get it work. 

When running the rules I get an error "Mesh does not contains any nodes or elements" and I think its this row of code that is the problem:

 strCmdForNewIdealization = "<NewIdealization Name=""Test Shell 1"" ID=""1"" Type=""1"" AddToFEModel=""1"" Color=""11087083"" CoordinateSystemID=""0"" MaterialID=""1"" EntitiesCount=""0""/>"

I copied it from an turtorial example but instead of using Shell elements it used Solid. So I changed it from Type = "2" (solid) to Type = "1" (Shell) accoring to this website:

What could be the problem? 
When apply an Idealization "manually" and not using iLogic you have to define the thickness of the Shells and I don't know how to do it in iLogic.

Thanks in advance!

I love how the only difference in the example between solid and shell is spelling "CoordinateSystemID" wrong. 

I see you are using AddToFEModel=""1"" not AddToAnalysis=""1""... not saying your wrong just something I see as different. Also could you put a line that shows a message before and after that line (or use the logger.debug in 2019.1) and make sure that is where your error is happening?

This is also a total guess but you could try adding Thickness=""<your actual thickness>""  and see if it likes that.

Thank you for your answer, I will check out your suggestions tomorrow morning! 

Yeah, I noticed the misspelling to, but the code worked out fine in the turtorial though. 

Another questions, how do I "uncheck" the box for "Associated Geometry" when using Shell Elements in iLogic?

For now it's automatically selected and I want to use "Triangles" or "Quadrilaterals" instead.

This is another guess but I would try AssociatedGeometry=""0"" ... as for picking the radio button GeometryType=""0"" for Quadrilaterals and GeometryType=""1"" for Triangles but this is all me looking at their general documentation and making assumptions.

The thickness command worked out great! Thank you!

But unfortunately the AssociatedGeometry=""0"" didn't seem to operate with me... 

 strCmdForNewIdealization = "<NewIdealization Name=""Test Shell 1"" ID=""1"" Type=""1"" AddToAnalysis=""1"" MaterialID=""1"" Color=""11087083"" AssociatedGeometry=""0"" GeometryType=""1"" CoordinateSystemID=""0"" Thickness=""0,001[m]"" EntitiesCount=""0""/>"

I did some debugging as you suggested and the only error left (hopefully) is the associated geometry. Running the Idealization-row above creates a new Shell Element Idealization but I have to click "Edit" to uncheck the Associated Geometry box by myself.

UPDATE: 

After some more research I found the solution. By typing in HasAssociatedGeo=""0"" will uncheck the Associated Geometry box. My code will now look like:

strCmdForNewIdealization = "<NewIdealization Name=""Test Shell 1"" ID=""1"" Type=""1"" AddToAnalysis=""1"" MaterialID=""1"" Color=""11087083"" HasAssociatedGeo=""0"" CoordinateSystemID=""0"" Thickness=""0,001[m]"" EntitiesCount=""0""/>"

Thank you for your interest!
