 July 31, 2014, 04:25 Semi-Circle in Tecplot. #1 New Member   MAT Join Date: May 2013 Posts: 6 Rep Power: 6 Hello All, I would like to know, how can I write ASCI data file for semi-circle. I know it for circle: ================================ [[Suppose the following example for circle of radius 20 at center(30,30) GEOMETRY X=30, Y=30, T=CIRCLE, FC=BLUE, C=GREEN20 ================================= Similarly, if any option to write semi-circle, please inform me. Sincerely yours MAT

Cheers, Scott

 July 31, 2014, 12:21 Thank you very much and one more thing Please #3 New Member   MAT Join Date: May 2013 Posts: 6 Rep Power: 6 Dear Scott, Its great, thank you very much. I can draw the semi circle in Tecplot. Actually, I am using FORTRAN code in my CFD simulation. In 2D case, if I want to create geometry like a circle, for example: a circle of radius =10 , Centre (50,20), in my FORTRAN code, I have defined the following way and in my output results file, Tecplot-360, 2010, I have seen geometry (circle). ================================================== ===================== WRITE(*,*)'GEOMETRY X=',50, ',','Y=',20,',' ,'T=CIRCLE', ',', & 'C=BLACK',',','FC=BLACK', ',', 'CS=GRID' WRITE(*,*)10 ================================================== =============== Now my problem is: For semi-circular geometry(upper half), how can I write the statements in my FORTRAN code (like above statements for circle)? Please help me in this regards. Sincerely yours MAT
