Hello everyone,
the most typical use of a circular transformation is for an axisymmetric model.
Since the axis of rotation is y, the default axis of rotation in the circular transformation should be the y axis, and not the z axis.
Moreover, since CalculiX prepares results on elements that extend circularly for 2 degrees, the default angle should be 2 degrees; and possibly the default number of items should be 45, to have a 90-degree view of the axisymmetric object.
Something like this:
Best regards
