Hi,
While checking a larger code of mine, I constructed a simple benchmark test, a simple twisted plate (as seen in the figure below). I ran the ACTB module and then the dynamic relaxation loop. I was expecting the plate to try to straighten out, but instead the plate tried to twist even more, which to me seams like a incorrect behaviour.
Could someone please have a look at my files and try to find what I am doing wrong (or could it be that there is a minus sign somewhere in the ACTB code that shouldn’t be there).
Hi @JFH, this is still an open question. Could you please have a look at my files and see if I am doing something wrong, or if there is potentially a small bug in the ACTB module.
