getting error: invalid command name "model" while executing model BasicBuilder -ndm3 -ndf3

[vasudeochaudhari]

Hi

For my problem, I have imported dxf file of 3d rig truss-structure. However, after performing all other steps when I am running the analysis, I am getting an error getting an error: invalid command name "model" while executing model BasicBuilder -ndm3 -ndf3.

it would be great if you can suggest me how can I fix the problem

Thanks Vasudeo

The error message appears because you have not assigned any editor (e.g. notepad) to .tcl files. Please do so and retry. It seems that there are some problems with your model, so the editor can show you the model file.

Thanks for your reply

By default .tcl file is opening with Wish Application in Windows 10, which is not getting change. I have recreated the truss model with elastic material properties, loads at top nodes and pin support at the bottom till getting the same error. Herewith I am pasting the .tcl file that is generating. it would be great if you can go through it and help me to fix the issue

Thanks and Regards Vasudeo

Can you attach the whole GiD project as a zip file ? The file association for .tcl can be changed to e.g. notepad easily.

[vpapanik]

I see that there are no lines commented out in the script (# before). Of course it cannot run like this.

[vasudeochaudhari]

Please find the attachment herewith the required files

While posting here, the text of script with # got converted otherwise original file has comments

Rig1.gid.zip

[vpapanik]

Your structure is ill-conditioned. Two trusses on the top are cut in two pieces, and a force is assigned in the middle, which suggests a mechanism. Consider also that ALL connections between truss elements are PINNED. Fix your model and report back.

[vasudeochaudhari]

Thank you so much for your replies and suggestions

I have made some changes in structure as you suggested. For this updated configuration I able to analyse structure in OpenSees. However, I am still getting the same error for reading the .tcl file in GiD interface. please find herewith the attached updated file

Rig3.gid.zip

[vpapanik]

It's because it is still a mechanism. Try replacing the trusses with beams and will work right away.

[vasudeochaudhari]

with beam element also it is showing the error

Rig3.gid.zip

even I tried the practice example given here and that also shows the same error

[vpapanik]

strange, try uninstalling the interface, delete the opensees.gid folder from problemtypes and install afresh again. Also assign notepad.exe to the .tcl extension.

[vpapanik]

Rig3.gid.zip has still truss elements assigned. Check again.

[vpapanik]

No reply whatsoever, so I consider this issue resolved.

[vasudeochaudhari]

Hi

Yes finally issue got resolved

Thanks for your cooperation

@vasudeochaudhari. I faced this problem on my laptop. I installed the software on my friend's laptop and the analysis was successful but on my laptop same error for all models. I hope you help me to fix this problem.

[vasudeochaudhari]

Dear Al-Haaj

For me, It was not a problem with GiD, but it was with opensees. Try to completely uninstall and reinstallation the latest version of Tcl/Tk. Initially, I also had some problems in my model, and however, as you mentioned, it is working on other systems so your model may be not be having those issues.

Hey, the GID interface shows the same error when I'm trying to convert my model into a tcl script, Could you suggest me what changes should I make to OpenSees to resolve this issue? I'm using the OpenSees version 3.1.0 and Tcl/Tkl version 8.5 (in-case the version compatibility shows any issues)
