xy data from graph plot to excel
Hi
I am trying to check whether my model is grid independent. I need to compare the velocity at a particular location in different star cd models with different mesh densities. 1. I tried to specify the coordinates and get the plot along the line joining those points. It returns an empty plot though. Is there a more accurate way to do that? How? 2. I want to know how I can extract xy data from a graph plot (field data) in Star CD to an excel sheet. Regards Radhika Gundavelli |
Re: xy data from graph plot to excel
Well you can allways try to use sensors at vertices you specify.
You can then scan values (e.i. x y z, u v w, p...). You can also save to a file, for instance *.grf that can be processed in Excel.. Try the help function in star. "help sens" "help gload" "help gval" "help sdat" "help close" |

Hi..
I tried the sdata command, but the corresponding .grf file is empty. I see the data in the registers when I say post registers from lists in the main menu. sdata, <filename.grf>, 6, 1, 1, user Thats the command I typed in. Is there something wrong wih that? Regards Radhika Gundavelli |

Thanks ...I got the .grf file

Re: xy data from graph plot to excel
I am still not able to do the second part i.e. extract xy data from a graph plot.
What I am doing right now is... 1. In the Star Guide: Extract/graph data / Field data data along a line line defined by endpoints cursor select two vertices 2. then I load SV in reg 4 3. Distance along a line 4. Create graph...to screen This displays the graph on the screen. I need x y data of this graph. I tried to say create graph ..to file ...but that creates a filename.plot file. which does not seem to be compatible with excel. Thanks in advance! |

When you have managed to get the graph in star cd, you can use SDATA to print the registers to text files. those you can than import into excel.
