Hello, I’m trying to use MOR on a simple scene where a disk shaped block of elastic is inflated by a cavity inside.
I am trying to use the default shaking as the function to animate (but I want to learn about how to animate specific functions).
Right now I am using the ipython notebook provided with my own scene, and it works up until phase3, where I get the following error:
[139658486859520] processing threaded sofa task in: /tmp/sofa-launcher-cOJiPc/phase2_prepareECSW.py [139658478466816] processing threaded sofa task in: /tmp/sofa-launcher-ijdbIZ/phase2_prepareECSW.py IOError : there is no /tmp/sofa-launcher-cOJiPc/elmts_disk.txt , check the template log to find why. Here some clue for its probable origin : - Your animation arguments are incorrect and it hasn't find anything to animate --------------------------------------------------------------------------- IndexError Traceback (most recent call last) <ipython-input-16-554842af6312> in <module>() ----> 1 reduceMyModel.phase3() /home/arthur/Documents/sofa/plugins/ModelOrderReduction/tools/../python/mor/reduction/reduceModel.pyc in phase3(self, phasesToExecute, nbrOfModes) 377 u.copyFileIntoAnother(results[self.phaseToSaveIndex]["directory"]+slash+fileName,self.packageBuilder.debugDir+fileName) 378 --> 379 self.reductionParam.massName = glob.glob(results[self.phaseToSaveIndex]["directory"]+slash+"*_reduced.txt")[0] 380 # print("massName -----------------------> ",self.reductionParam.massName) 381 u.copy(self.reductionParam.massName,self.reductionParam.dataDir) IndexError: list index out of rangeCan anyone tell me what I am doing wrong? Or point me towards a similar post, I do not fully understand how the animate function works from this documentation.
I’m using the master branch of sofa (so that stlib will compile with it)
The scene and needed files can be found at:
https://uchicago.box.com/s/8v2wkv36csfmadhfk5l5phv0cn4j7sy2Hello @olivier-goury @felixvanneste,
I found your contact info on the MOR github page and I was wondering if you could help me out here.
I have changed my setup a bit but I am still getting the exact same error. (my code and files can be found here https://github.com/ripl-ttic/SofaFramework-Docker/tree/problem_illustration). [NB: the branch is not the master branch]
About: I am using ubuntu 18.04 and a set of compatible Sofa/STLIB/SoftRobots from this fall, (I couldn’t find a version of STLIB and SoftRobots that was compatible with 20.06 so I am using verions that were compatible with the master branch of sofa)
My environment is fully specified in the Docker file in this git repo where I have specified the commit of each library package I am using. https://github.com/ripl-ttic/SofaFramework-Docker/tree/problem_illustration/Dockerfile
I chose to do this so I could run STLIB and SoftRobots in a stable way, if there is a way to run STLIB/SoftRobots/MOR with Sofa20.06 I could not find it.
To run the code without docker you will need to copy the DiskModelOrderReduction.ipynb file from /workdir/MOR_test and run that.
Note: in order to run jupyter notebooks in docker you need to have x11 forwarding, I use x-docker to do this.
On a related note, another question for @olivier-goury and @felixvanneste: will Model Order Reduction be compatible with python3 in the near future?
EDIT: My original follow up has seemed to disappear after I tried to edit it. I have posted it below.

see also the readme.md on that repo for instructions on running the code.

Hi Arthur,
Sorry for the late reply! I am not sure where the problem comes from, but looking at you scene, there is no reason why it should not work, and I think it should only be a minor issue. I will let @felixvanneste reply as he is more skilled in python related issues.
About the python3 compatibility, the answer is yes, it should become compatible very soon.We keep in touch,
OlivierHello Arthur,
sorry for the late reply.
Can you check the log where the reduction is crashing ?
Taking what you have shown above as an example, in :
/tmp/sofa-launcher-cOJiPc/Maybe we can debug this together by visio if you want, it will be easier.
You can send me a mail directly in order to organize that.Félix
