I have extruded the first plane to 500m to create the first part of my pipe. I extended the pipe to 1,000m by creating another plane on the end of my first pipe. When I try to extend the plane to another 500m, there is an error. Not sure why this is happening, please help!
The error is: Feature parameter too large.June 1, 2021 at 10:24 amKeyur KanadeAnsys EmployeeWhere are you extending? Is it DM or SpaceClaim?
Better use scale down model. Mesh it. Then read in Fluent. Then scale it up using Domain -- Mesh -- Scale
47.3.1. Scale Mesh Dialog Box (ansys.com)

June 2, 2021 at 1:47 amLeonLowSubscriberI am using DesignModeler! My steps are Geometry, Mesh followed by Fluent. If I were to scale it down in SpaceClaim, will I be able to scale it back up to 5km? As far as I know, you need to connect a few 500 m pipes together to make it to 5 km because ANSYS only allows a part to be 500m maximum.
I tried using SpaceClaim but I am unable to find the anchor point for a circular pipe! Please help!
June 2, 2021 at 10:31 amRobAnsys EmployeeDesignModeler has a large body option, and SpaceClaim doesn't seem to limit dimensions. Note, a 5km pipe will need a lot of mesh as you'll want 10-20 cells across the diameter and an aspect ratio of between 1 and 7 in the bulk mesh. What are you trying to model?
June 2, 2021 at 10:44 amLeonLowSubscriberI am trying to create a 2 simple models of
Case 1: 5km circular pipe in which the surface temperature is around 90 Degree Celcius and the fluid inlet temperature is 30 Degree Celcius. I would like to view the temperature contour across the circular pipe.
Case 2: 5km circular pipe with 1/4 of the pipe insulated from the surroundings and the other 3/4 is exposed to 90 Degree Celcius. All conditions same as Case 1.
June 2, 2021 at 10:48 amRobAnsys EmployeeIf it's straight and vertical (or gravity is off) then use 2d axi-symmetric in Fluent as you may then have enough mesh to model this.
June 2, 2021 at 10:49 amLeonLowSubscriberIt is horizontal! Should I use SpaceClaim to do this?
June 2, 2021 at 11:08 amRobAnsys EmployeeDesignModeler is fine, just turn on large model support. I assume you can ignore gravity?
June 2, 2021 at 12:47 pmLeonLowSubscriberThanks for helping! I just started using ANSYS last week. Will try to do this
