I have an issue which keep occuring to me in this particular part and I don`t understand why its occuring. 

Basicly I run optimization proccess for a part with several load cases. Then when I try to analizing the optimized part, the analysis shortly fail and spit out: error code 61.

I tried running the analysis for several optimization solutions facing the same issue time after time.

Unfortunately,  I couldn`t find any usuful information regarding this error code.

I added the Inspire file and did my best making it easy to understand.


Please addreass this topic and help me solve the problem.

I tried running the same file on other machine, with the same inspire version (2017.2.1) and it worked. Then I tired reinstaling inspire on my machine while making sure its instaled on a new location, which path contains only english characters.  

to my disapointment, it didn`t help. 


I need version 2017.2.1 to avoid compatibility issues with other team members. And as I memtioned it worked on a different computer what makes this problem stranger.


I appriciate the quick reply and apologize for my english.

Thanks for the reply and sharing all information.I am not sure about the root cause of this error.

We normally try to avoid special character (_ . % etc)used in part name/file name/user name.Try changing run folder to different location from preference option.

Please find below the reply from the development team.


I think the error 61 is related to empty optiAnalysis.fem. During reanalysis run, HM must have failed to generate the deck. We need entire topology optimization folder  or after importing topology results please save a stmod file and send us that file. 


Requesting you to share same folder and .stmod file here or use ftam link (dropbox) available in my signature.

I am really sorry for the long time it took me to answer.

I will share the folder if you will explain to me where can I find this file and how much files there are exactly.

Thank you.
