Re: extract streamtraces with python

Hi,

You might try the TecUtil.CreateStreamZones function.

Re: Separate grid and solution files -> zone dimension mi

Hi Eric, Thank you for providing your code. It looks like there is a problem in yoru second call to TECINI. Your FileType_Solution variable is set to 1 at the top of your program, but 1 is for Grid files which is not what you need when opening/creating the Solution file. Perhaps setting it to 2 (for...

Re: Making threshold for variables in makro

Morten,

You can find the syntax for the GETFIELDVALUE and SETFIELDVALUE commands in Tecplot Reference Manual which is in the Doc folder within your Tecplot folder. The reference manual filename is tprm.pdf.

Re: Making threshold for variables in makro

Morten, Tecplot's macro language does have an IF statement, but it only works on variables that are declared within the macro, using the VARSET statement. You can access the data you have loaded into Tecplot from the macro language, but you have to do it using function calls. Specifically, you can f...

Re: extracting data from streamtraces

Hi, When you convert your data to Tecplot format and load it into Tecplot, and you see that the Iso-Surfaces and Slices controls are not active ... That is a good indication that Tecplot does not think you have 3d elements (bricks, tetrahedrons, polyhedrons). Slices and Iso-surfaces only work when y...

Re: Contours on contours

Not in the macro language. You can acess it in an addon or in a python script though.

Re: Contours on contours

Thank you. A macro can read the data you have loaded into tecplot, and if you extracted a contour line that represented u=0 to a zone then a macro could read the points in that zone too. It could check the values of v for each point in that zone and mark in some way those points which had a value of...

Re: Contours on contours

Thank you for the additional information. If I understand correctly, you were hoping to use the contour at u=0 to create a zone which was a subset of your original zone. (Such as all the cells where u <=0). Tecplot thinks of a contour as the line separating contour color bands. This is what it will ...

Re: Contours on contours

Morten,

Not sure what is happening here. Would you please go to Data/Dataset Info and click on the Zone / Variable Info tab and tell us what is displayed in the lower left portion of that dialog? Specifically we need to know what values are shown for I, J, and K.

Re: Average value for variable over entire domain?

Hi, You might be able to do this with Tecplot's Analyzer. Go to Analyze/Perform Integration and select Average from the dropdown list at the top of the dialog. Then select the variable whose average you want to calculate, select the zone over which you want to calculate the average and then click th...

Re: Grid, Solution Files and Connectivity Sharing: How to ??

Kostas, When you load a grid and solution you need to load them together. So you would go to File/Load Data File and choose the Tecplot data loader. Then click on the Multiple Files button at the bottom of the dialog, and select both of your files (grid and solution). Then Tecplot will try to load t...

Re: 3D Cylindrical Visualization

Kamal, When you go to Data/Create Zone/Circular, the I is the radial dimension, and the J is the circumferential dimension. If J is set to 4, then you will not get a cylinder because there are simply not enough points in the circumferential dimension to make a nice looking cylinder. Your original da...

Re: 3D Cylindrical Visualization

Hi, I tried transforming the dataset you included in this threrad on 25 Oct, and found that the transformation worked perfectly. The resulting plot looks like a flat plane because the axis ranges are not getting reset after the transformation. So it looks like all you need to do is reset the axis li...

Re: 3D Cylindrical Visualization

Thank you for the additional information. It now becomes clearer what you are trying to do,. although I do not yet understand the reason for wanting to create another cylindrical zone in Tecplot. 1) When you create the new zone (a cylindrical zone) Tecplot reads the limits of X,Y, and Z from your ex...

Re: 3D Cylindrical Visualization

Hi Kamal, Still not sure what you are trying to do, but if you are doing the following: 1) Load a dataset which has coordinate variables and some other variables (like "Sw"). 2) Transform the coordinates of this dataset from polar to rectangular (adds two variabels which are then assigned ...
