Can Tecplot do selective blanking on grid? Others?
Hi,
I'm trying to implement an overset code and I've been using tecplot to visualize my previous data. I need to do blanking on selective cells due to my overcode code. Is tecplot able to do this? It seems that it is only able to do some simple blanking based on equations etc. Else is there other software which can blank out the cells I specify? Like CGNS or ensight? ... Thanks |

i use tecplot 10 and it do this
>plot > blanking > value blanking or ijk blanking and then use suitable criteria |

Hi tks. But what I mean is if I want to blank specific cells like i=10,j=5 , i=7, j=6, Can Tecplot do it?
Or is there other software which can? |

You need to define an iblank array and include that as part of your grid file. Then you can use tecplot to blank using variable and choose iblank as the variable to blank on. If you use an iblank array there are several pieces of software that can operate on blanked grids, including fieldview and the overset grid tools package from Bill Chan at NASA.

Tks ag.
Supposed that I 've a rectangle grid, FVM, cell-center, 10x10 Then I create an array blank(10,10) in fortran. if I want it blank, I let its value =1, else 0. Then what to I do next? How can I let tecplot know which cells I want it to blank? Thanks again |

Typically IBLANK = 0 for cells that will be blanked (standard overset nomenclature). Then under the plot menu choose blanking -> value, and select the iblank variable as the variable to blank on. You will also need to set the cutoff, so that blanking occurs when the variable value satisfies the constraint.

Got it! tks

u can do any blanking with value blanking, for this add an additional field variable, e.g., blanck-field and give 0 value to for where u like to blank and 1 for other positions, then use value blanking and blank value (based on blanck-field) that are not equal to 1
