Dear experts,
I´m performing a non-linear buckling analysis under ANSYS Mechanical APDL (v14.5) using an input file that processes the last converged step to generate some etable output.
When run in GUI everything goes fine: the non-linear buckling analysis is performed until it becomes non-convergent, the previous to last step is selected, and the wanted etable is generated. However, if the input file is run in batch mode (command line) (*), it dumps the following convergence error and exits without generating the etable:
*** ERROR *** Solution not converged at time 0.6885 (load step 1 substep 71). Run terminated.
I´ve tried some workarounds using " NCNV,0 " (**) or " NERR,,,-1 " (***) commands. Both commands work in GUI, i.e. they do not exit non-linear analysis and continue execution, but only NERR does it in batch. The problem is that this way more non-convergent steps are performed than necessary so both runs will be slower and, more important, I can´t select the "previous to last step" to get the etable results I want.
PLEASE, WOULD YOU HELP ME ? Any help is highly appreciated! Thanks in advance!*Command to run ANSYS from windows 10 command line:
"c:\Program Files\ANSYS Inc\v145\ansys\bin\winx64\ANSYS145.exe" -b nolist -s noread -p ansys -i mynonlinear.txt -o mynonlinear.out
**NCNV sets the program behavior upon nonconvergence if the solution fails to converge: 0= Do not terminate analysis, 1= terminate program execution and analysis, or 2= terminate analysis but not execution (valid in SOLU processor).
***NERR,,,-1 Ignores all errors and performa all non-convergent steps in non-linear analyisis (valid in all processors).
