Hi all,

I want to write pre-defined x nodes values in the CMC_constraint.xml file.
e.g.
<x_nodes>
<ControlLinearNode name="">
<t> 0.20999999999999999000 </t>
<value> 0.01000000000000000000 </value>
</ControlLinearNode>

Is there any easy way to write the values (stored in excel file) to xml file in the above format? Anyone has experiences?

Thank you in advance,

Ruoli

Hi Ruoli,

The excitation editor should be able to help you. It reads sto files and writes XML files. Please give that a try and let me know if you need further help.

Hi Ayman,

Thank you for your reply.

I have tried excitation editor, but I can not really save it, always got runtime error with java.exe. I saved the predefined controls (e.g. gasmed_r) in a .sto file , then loaded control of gasmed_r from a regular cmc_constraint.xml. When I right click the grid panel, there is an option 'import data from a file', which I can load the predefined .sto file. I have tried to 'save, save as or new', but error window pop up. Did I do something wrong?

I knew it is possible to manipulate excitation at particular selected point, but it takes time to edit each point.

Thank you,

Ruoli

Hi Ruoli,

Can you please post a short version of your .sto file to try it out in my environment? You could also use a pre-existing control constraints file and edit it in the excitation editor.

Best,

Hi Ayman,

I have uploaded a short .sto file as an attachment (changed to .txt for uploading). I can not either save it in an existing control constraints file or the software just crashed.

I tried to edit in excitation editor, but it is kind of taking time to edit each point.

Hi,

The excitationEditor (from the Edit menu) doesn't directly edit .sto files, however the entry point from the forwardTool allows you to do that, so what I did was:
1. Load any model into the GUI.
2. Open Forward Tool and browse for your control.sto file (I removed excessive blank tabs beforehand) as a controls file.
3. Use pencil tool to edit the file.
4. Save the file as "control.xml".

Use the "Help" button for quick editing tips in the excitationEditor.

Hope this helps,

Hi Ayman,

What you suggested works!

Thank you,
