Thanks for your tutorial. I have a question regarding the concept of a rigid body and couple constraint. How do these constraints distribute a concentrated moment on the surface? Is it uniformly or linearly? I am also curious why the results are so different.
Hi. You are welcome. Happy new year. For applying a concentrated moment to a surface or section, I always define coupling constraint but I have also seen some tutorials which use rigid body constraint. I have not used rigid body constraint at all but I know that using coupling constraint is totally correct and it works. When you define a coupling constraint, it means that the initial distance between the RP and nodes of the selected surface will not change during the simulation. So the distribution of moment will be in way to satisfy this condition.
Very nice tutorial . Thanks for your teaching
