 September 4, 2011, 17:12 Changing the global coordinate system? #1 Member   Join Date: Oct 2010 Posts: 63 Rep Power: 8 I applied the Point Parameters in Flow Simulation. I want to change my global coordinate system. I want to move it, so that it is not in the middle of the Point Parameter plain, but at any of the Point Parameters plain corners. Is that possible? Can I change it? http://imageshack.us/photo/my-images/824/11ax.jpg/ Last edited by wyldckat; September 3, 2015 at 18:00. Reason: disabled embedded images

Instead of both axis beginning with 0, and ending with some positive number, both of my axis begin with negative number and end with positive number: http://imageshack.us/photo/my-images/850/55736240.jpg/ How can I use that local coordinate system i order for my 2d coordinate system in Tecplot to begin with 0?

By default the coordinates are from the global coordinate system but you can add the parameters from the parameter list. They are called x (cartesian), y ..., z ... and then you have the possibility to select a different coordinate system. http://imageshack.us/photo/my-images/18/coord.png/

 September 6, 2011, 07:49 #5 Member   Join Date: Oct 2010 Posts: 63 Rep Power: 8 Thank you Boris. Do I need to define a new coordinate system (Insert->Reference Geometry->Coordinate System) before I add the Cartesian X,Y,Z parameters in the Point Parameters list? For some reason I am getting the same values for both global coordinate system and cartesian: http://imageshack.us/photo/my-images/20/33352652.jpg/ Why?

 September 6, 2011, 08:01 #6 Senior Member   Boris Marovic Join Date: Jul 2009 Posts: 468 Rep Power: 15 Ok, let me rephrase your question: Can you get values referenced to a coordinate system that you haven't defined yet? have a closer look on my image, especially the point parameter settings I did.

 September 6, 2011, 08:57 #7 Member   Join Date: Oct 2010 Posts: 63 Rep Power: 8 Makes sense. I am apologizing for asking such a stupid question. Of course I needed to define a new coordinate system first. Sorry. I had to click on "Global coordinate system" and then click on the newly created "Coordinate system 1". I got it. Sorry for disturbance, and thank you once again. I truly owe you a favor! Last edited by george85; September 13, 2011 at 18:18.

 March 22, 2014, 12:53 moving coordinate system to center of 180 degree bend in flow 3d #8 New Member   Maryam Ak Join Date: Mar 2014 Posts: 2 Rep Power: 0 Hi dears I'm working on my these that is about simulated a 180 degree bend (U-shape) via Flow 3d software. So I have a question about coordinate axes. I need to put the coordinate axes in center of the bend. But in flow-3d, coordinate axis is in the corner not in the center. I should use cylindrical coordinates to simulate and after that I have to use this data for drawing contour and stream line via Tecplot. So it's necessary to me that put coordinate axes in the center of the bend. I search a lot about moving coordinate axes in flow-3d but couldn't find any text and help about it. Can you help me? Thanks a lot for your attention.
