Hello,


Has anyone had a similar issue and know of a fix?


I get .plt output files from my CFD code which contain the entire volume solution. I want to import this into Tecplot and then write out only the surface data as an ASCII file. When I do this, for some reason Tecplot saves the entire volume connectivity data and the ASCII file ends up being very large (think GB instead of MB). For an unsteady DES case over long periods of time, this is a lot of data. I really only want the surface data.


I have tried to delete the volume zone in Tecplot before writing it out, but somehow Tecplot magically saves the data anyways.


Also, I am doing this with a Macro. There seems to be some inconsistency between doing it manually and doing it with a Macro. When I write out the data manually, it writes out correctly (correct file size with the correct data), but when I write it out using the Macro, it is incorrect. Obviously I am using the same procedure since it is easy to just record the procedure into a Macro and then rerun it.


Any ideas would be helpful? Thanks!

If you want to write only the scalar information (no cell connectivity) you can use "Tools->Write Data as Formatted Text". This will allow you to select the set of zones and variable to write.

This will only allow you to write nodal variables. If you have any cell centered variables you'll have to convert them to nodal first by using the Data->Alter->Specify Equations dialog. To do this, type the equation:

{MyVariable_Nodal} = {MyVariable}

And be sure to select "Variable Location" as Nodal in the dialog. The Specify Equations dialog allows multiple equations so you can convert many variables at once.

I hope this helps.
