MARS - A Software Dedicated to Advanced Concrete Modeling

There is a problem in running the current creepUD subroutine in combination with openMP.

The simulation with marsO shows excessive increase in kinetic energy. Mohammed observed the same problem in the last weeks (with the earlier versions of that time).
The simulation with marsD runs relatively stably.

The results of a somewhat larger specimen, also run with marsD show a constant frequency, constant amplitude noise (where does it come from ?).

When the debug version and OpenMP don't give the same result, it usually means the code is not written correctly. There are a few things to look for: (1) there is a bug in the code; (2) the code is not OpenMP compatible, meaning the code violates how OpenMP handles memory.

To check (2), run the OpenMP version while setting the number of threads to 1. If this gives the same results as the debug version, (2) is the issue, otherwise, check (1).

Also, I noticed you are still importing FE node list into a diffusion node list. I suggest checking my previous replies and use the approaches described in the development notes.

any insights regarding the oscillations in the MarsD run, see jpeg file in previous attachment ?
