Hello, I'm getting this error when running my simulation.
*** ERROR # 4966 *** Minimum time increment reached, analysis aborted.
I do not know how to solve this problem. I have attached the .hm file. Appreciate any help thank you
please check these tips for debugging:

you cshould check the _nl.out file as well:

It looks like some issue with force balance.
Adding NLADAPT to increase the maximum number of cutbacks, or reducing the minimum increment might be an option.
in your NLOUT use SVNONCNV to save the last converged increment.
Also using PARAM,NLMON,DISP to save all the iterations of the NL run, and checking if there's something strange.
Hi Adriano,
Thank you for your answer. I'm stuck now with another simulation. I tried everything you mentioned but I'm still getting this error:

I'm stuck and I don't know what to do …
I'm attaching below the .fem of the simulation if you'd like to have a look.
Thank you so much and I look forward to your response
