Error no. 486 in bemess

Hello,
I have an error message
“+++++ error no. 486 in program BFAT_BEME_ITER
No convergence in strain iteration in element/node(neg) -133 LC 4040
Should not happen. Please send the problem to the SOFiSTiK Support.
This check can be switched to a warning with CTRL WARN 486.”
while trying to run decompression check in bemess and csm and after few hours im out of ideas how to solve it. Thank you in advance if anyone can help.

-PROG CSM urs:6
HEAD DECO Design

DESI DECO $ decompression check
grpd 2

CTRL FILE ‘desi’ $ filename for the created input file
END
-apply “$(NAME)_desi.dat”

Can you upload the system that we are able to reproduce the problem?

The problem is, that there is no ULS design before the decomression check. So BEMESS could not find a given reinforcement for the DECO.
Please insert a DESI ulti in the CSM_DESIGN:

!+!CHAPTER DECO-NIEDZIAŁA
-PROG CSM
HEAD DECO Design
DESI ulti $ decompression check
DESI DECO $ decompression check

Best regards,
Jost
