Dear all, 

I am implementing some energy based stopping criteria for my analysis that requires numerous remeshing processes. I noticed that if I use XIT it gives me a lot of problem about memory access, this problem looks solved if I used LSTOP = 1, by adopting the URDFIL subroutine. My issue with that is the following, if I do not add the *ENERGY FILE keyword it won't work at all and analysis progresses as there is no criteria. If I put this keyword it works. The main issue is that I noticed that performances are a bit decreased since he has to open the .fil file. Is there any other way to use URDFIL without creating the fil file? I am doing something wrong that downsize the performances? 

Thank you in advance for any suggestion!
