Hi everybody, 

I did not undestand why the mderator locked the topic: "I want to see the failure!", since I have not jet resolved my doubts. 

So, I refear to it for previous posts

https://forum.ansys.com/forums/topic/i-want-to-see-the-failure/

 

I answer to peteroznewman

 

as you can see in the attached figure, the number of steps set by me in the file is not 0 but 1, so, I do not understand why the program read 0. I have also tried to increase that value but the error still exists.

Dear peterznewman,

I tried to re-do the exercise proposed in the file shared by you, but it does not run. I set all parameters in the same ways but the error message occured again.

- firstly, I had to add the "bi-linear histropic hardening" behaviour to the default steel material in order to see plastic strain.

- more over, when I passed from the plastic analysis to the failure analysis (ekill script) the program does not solve the problem, and thefollowing error appare in the "solution information":

PARAMETER FAIL_STRAIN =     0.000000000   

 PARAMETER STEPS =     0.000000000   

 *GET  TIME_END  FROM  common    ITEM=STEPCM   REAL N=    2
    VALUE=  500.000000   

 *** ERROR ***                           CP =       0.391   TIME= 16:44:07
 Attempt to divide by zero in parameter expression.                     

 *** ERROR ***                           CP =       0.391   TIME= 16:44:07
 The above error occurred processing field= TIME_END/STEPS              
  Line= *SET,timeinc,(TIME_END/steps).                                  

 PARAMETER TIMEINC =     0.000000000    

 

So, i tried to eliminate the following lines (7-9 lines) from the script in the command line:

timeinc=TIME_END/steps

time,timeinc

solve

Now the program end the solution process but I do not obtain the expected result.

 

Please, help me to understand the error

I don't write scripts, I only use them. Other members are welcome to take a look.

Good luck.
