Dear Sumit, dear Amanj, dear Wayne,
Thank you for your interesting questions. Sorry for my late answer, I was abroad with no internet connection.
Sumit, Tecplot Inc, is currently working on leveraging the latest performance capabilities within the add-on development kit (ADK). They found a bench of interesting new features to implement, such as subzone-load on demand. Tecplot wishes to have the ADK compliant with the previous versions, i.e. to be able to update add-ons just by recompiling them with the new library. As soon as the new ADK in finished, we will make a new loader available. I will keep you in touch regarding it.
Amanj, from what I understood from TELEMAC 3D results data (r3d_XXX.slf files), you have only the surfaces written. Please note that if you wish to have 3D visualization, it will be interpolated from your surfaces by Tecplot.
There is many ways of visualizing 3D data. For example, you can set a slice on your Y axis, extract this slice (Data->Extract->Current Slices / Slices over time), seed streamtraces on it, display vectors…
Please let me know which features are of interest for you.
Wayne, please find the latest loader for Tecplot 2013 on windows 7 enclosed in the post #14326 of this topic (Page 3). Let me know if you this works better for you.
Hope these help, best,
Antoine
