Problem:

 Is this Considered an Anchor in AutoPIPE?'

Example: #1

A pipe continues with a fin pipe that extends 2000 mm in the Y direction from the anchor part, Since the fins and frame are welded, the anchor type is specified as rigid as fixed endpoints.

would this be an anchor?

Solution:

 keep in mind that AutoPIPE has a setting for where the user can specify what is to be considered rigid. See settings located at the bottom on the Edit model options dialog.

Anything assigned with a Rigid stiffness will have this amount af stiffness assigned to that bearing spring direction. Example, rigid v-stop support, will have a stiffness of 0.100000E+11 lb/in stiffness in the +ve / - ve vertical directions.

In the case of example #1 above, if the welded pipe and fin supports have a stiffness assumed / calculated to be close to the rigid stiffness value then model as a Rigid. However if the assumed / calculated stiffness value is considerably less than anchor stiffness specified on the dialog, then recommend to model with more accurate stiffness values.
