Single Rotational Constraint

[engltayl]

Is it possible to create a single axis rotational constraint at a keypoint(point) in workbench simulation rather than a rotational constraint in all 3 axes? I just want to constrain a keypoint with a similar contraint as dk,,roty would be applied in ansys classic.

thanks

I believe the closest you'll be able to come is using the remote displacement, but you still have to select a face.

In WB, you can't apply any solid body constraints, because there are none in the input file generated (WB translates all solid body loads to the underlying FEM). So what you'll have to do is insert a command snippet, use selection logic (or create a named selection out of the corner), and then apply the constraint manually.

However, just be careful that you're not trying to apply rotational constraints on solid bodies, since all the solid elements only have translational DOFs.

Good Luck

Thanks for the reply, I actually found a way by the time I read this. I was able to create a rotational constraint by creating a slection named point1 and using a command with the following code:

/prep7

cmsel,s,point1

d,all,roty

allsel

finish

/solution


thanks
