I've been doing some experimenting with large deformation analysis.
I want to twist the end of the beam around, several times (don't ask why, I just need it done).
In a large deformations analysis you can not prescribe a tangential displacement in radians. It has to be "unit of length" mm in my case. So I did this for the circular curve on the end of the tapered bit
I get it to rotate about 360 degrees, no further, however large I make the value for prescribed displacement (the value in the field is now 9000mm (160 full turns....).I stopped the analysis after I found out that displacements no longer increased.
Any body knows how to tackle this?
Shall we classify this as a bug?
