Load -> Displacement 1/4 circle move?

[wojtekmath]

Hi
i can make move x,y,z direction in rectangular cordinate system. But how to make 1/4 circle move? I try change cordinate system to cylindrical/spherical but it works like in recatangular.

 

[rb1957]

x^2+y^2 = R^2,
x = R*cos(theta),
Y = R*sin(theta),
0<theta<pi/4

??

Thanks for your answer
i have done like that:
1. I made two function: vs. time function with sin(360*!x) and with cos(360*!x).
2. I made two load -> displacement, first x direction (time/freq dependence function with sin()), second y direction
(time/freq dependence function with cos())
3. I have to use sol 601 becaue "vs. time function" don't want work with other solution .
4. it works .

There is my another question: is any other simple method? Why i can't use angle move in cylindrival cordinate system. Some time ago I symulated "Spherical roller bearings" with spherical cordinate system and then it work excelent - but there it was constraint.
My observation: spherical and cylindrical dordinate system works only with constaints. It doesn't work with loads.

Why do not use Enforced Rotation?

Hi
You can probably do this in both a non-linear transient solution and a non-linear static solution.

But I assume there is a purpose with this that goes beyond the 1/4 circle move. What is it that you want to simulate?
