Open mat2tecplot.m in a text editor, search for "magic number"
which is the version number, change to earlier version Wen

I have another problem when I put TDV100 and TDV010. The TDV100 give error as : "out of space while allocating var names" and /invalid header in binary datafile" and "unable to read binary datafile header.
The TDV010 give error as: unexpected end of file in datafile header

Oops, that means you would have to experiment a bit, the binary file format may have been changed from 10.0 to 11.0.
not sure what exactly your line of the magic number looks like unless you post it also try "#!TDV101" which means 10.1 or "!TDV75 " for version 7.5 notice there is a space after 75

I've tested (TDV101 and TDV75 ), but they give the same error as TDV100. all older versions TDV105 give the same error

I do believe you will need to upgrade your Tecplot license to the new version, as the option to use “Preplot” does not apply to the mat2tecplot.m application.
Preplot is used to convert Tecplot ASCII formatted data to Tecplot binary formatted data – which is not the situation for the use of mat2tecplot.m Here is a link to the product page on Preplot (and TecIO) if you want to learn more about this application: http://www.tecplot.com/downloads/teciolibrary/ . BTW – Preplot is already installed on your computer in the Tecplot 360 “bin” folder. Contact Tecplot via the email  sales at Tecplot dot com  to get your license upgraded. Scott

Tecplot intern Devon Simpson has written a blog that provides a script and data showing how to use Wen Long’s Mat2Tecplot.m converter. The blog is located here: http://www.tecplot.com/blog/2014/07/28/createtecplotformatfilesmatlabdata/ .

Hello Sarah,
i have data which is updating (iterating method) as isotherms computing in matlab(its updating until we reach the convergence creteria) my question is : how to get the last image in tecplot file (.plt)??? Thank you so much

Hello,
Could any one tell us how to use this way to visualize isotherms and streamlines in 2Dimensions. Thank you

Isotherms can be produced via our contour groups and using a surface contour. Check out some the videos on using Tecplot here http://www.tecplot.com/products/tecp...deotutorials/ Best Durrell

Superpose two matlab figures or more in one figure like these

Hello and thank you so much for your quick reply
what i am intresting in is how to put many contours on the same matlab's figure? like these below: look to one of these figures ,please let's choose the first one on the left, did you observe that on the first contour (dashed lines), there's another one but with (solid lines). how can i make the same thing??? NB: no way to imagesc them at the same time on the matlab code, we obtain these contours one by one .... so i thinking about export them (2 contours or more) together to tecplot wishing make the necessary postprocessing treatment in order to get the same result Thanks

I have tried to do as you but unfortunately, it failed to generate the tecplot file. My code as following: tdata=[]; tdata.Nvar=5; %number of variables tdata.vformat = 2*ones(1,tdata.Nvar); %Double precision for each variable (optional) tdata.varnames={'X','Y','Z','TEMP','TEMP_GRADIENT_ NON_UNITY'}; tdata.cubes(1).zonename='TEMP_GRADIENT_NON_UNITY'; %any name %tdata.cubes(1).zonename=eval('TEMP_GRADIENT_NON_U NITY'); %any name tdata.cubes(1).x=X; tdata.cubes(1).y=Y; tdata.cubes(1).z=Z; tdata.cubes(1).v(1,:,:,: )=TEMP; tdata.cubes(1).v(2,:,:,: )=TEMP_GRADIENT_NON_UNITY; mat2tecplot(tdata,'TEMP_GRADIENT_NON_UNITY.plt') I have gotten the following error: Error : cube 1 v 2nd, 3rd, 4th dimension must be of the same size as x, y, z To your knwledge, my domain is 201*201*201

It seems that the sizes of your arrays are not the same. Here is the error display lines in the script: if(Imax_v~=Imax  Jmax_v~=Jmax  Kmax_v ~= Kmax) s=1; display(['Error : cube ' int2str(icube) ' v 2nd, 3rd, 4th dimension']); display([' must be of the same size as x, y, z']); Are you sure that your arrays (including x, y, z) are all 3D with the same size?

What I see here is that X, Y, Z are 201*1, you need them to be 201*201*201 like TEMP. First, use "meshgrid" function to convert X, Y, Z to rectangular grid. It should work then.

You seem to not understanding that: tecplot data file does not contain information about "contours", it is designed to have the data that the contours should be based on. So instead of trying to put "contours" into the data file, just put in the original data. Contours are viewable once you have the data file in .plt format and open it in tecplot software. Plus: post your code directly so that we can help Wen
