[MOR Plugin] Step 3 Fails: .state Files Not Generated for Soft Robot Setup

[yu-mei]

Dear creative SOFA community (@bakpaul @alxbilger @hugtalbot @olivier-goury @EulalieCoevoet @damienmarchal),

I'm encountering an issue while running the Model Order Reduction (MOR) pipeline on my soft robot model.

Step 1 and Step 2 both complete successfully, whether executed via script or the GUI. However, Step 3 fails, and I receive the following logs during steps 3 and 4:

PHASE 3 --- 58.845741987228394 seconds ---

Although I do get a final reducedModel.py file in /ROM_results, it does not contain any meaningful result. Also, step2_stateFile.state under /ROM_results/debug/ is empty.

---

📁 Folder & File Overview

• SoftArm_Original.py: the model I want to reduce
• ROM_results/: intended output directory for reduced model results

---

❓ What I've Tried

• Verified that the model animates properly in Step 1 and 2
• Tweaked ObjToAnimate(...) and rangeOfAction parameters

---

Any insights or suggestions on how to properly generate the .state file in Step 3 would be greatly appreciated!

Thanks in advance for your help! 🙏

Best regards,
Yu
