Cylindrical coordinate sysyem-Gambit

AI Thread Summary
The discussion revolves around using Gambit for a 3D simulation that requires a cylindrical coordinate system (r, z, θ), but the software defaults to Cartesian coordinates (X, Y, Z). Despite changing the coordinate system to cylindrical in the Tools menu, the user still sees Cartesian coordinates. A suggestion is made to mesh a slice and use the extrude option to create a cylindrical mesh. Additionally, creating user variables with transform functions is proposed for plotting against cylindrical coordinates. Ultimately, exporting an ASCII file in Cartesian format and converting it to cylindrical coordinates is recommended as a workaround.

hi,
i am doing a simulation of 3D problem.i want to draw it cylindrical coordinate sysyem(r,z, o).but gambit shows X , Y , Z Coordinate . how to do in cylindrical co ordinate , will it show r, z and o axis ?
i opened the Tools command button then i changed the co ordinated system to cylindrical and I acctivé it . but it still at cartesien coordinate

please reply

From what I know, Gambit is the mesher used for Fluent (neither of which I've used). Speaking from another ANSYS mesher, ICEM, what we typically did when trying a cylindrical domain is to simple mesh a "slice". After that, there is an extrude option. That option gives you the option to basically revolve the current mesh around. That..gives you a cylindrical mesh.

If you simply want to plot variables against cylindrical coordinates, then just create user variables using transform functions.
 
thank you for your reply but t is not what I seek to carry out, indeed gambit uses the Cartesian coordinate , but I wants apparaitre the cylindrical co-ordinates (R, Z, O) because I will export an ASCII file from gambit containing the cylindrical co-ordinates.
thank.
 
At the very least, you could write out the file in some formatted text file, and then write a converter to read in the cartesian values and calculate the cylindrical equivalent.
 
thank a lot, i will try..

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
