I have tried to export my STAR 3.15 vertex results to ENSIGHT - Format but without success. I have received the message "Error Scalar Concentration 4 is not on the Data File". Is it another STAR - NT -Version bug???

What can I do???

There were problems with the ENSIGHT exporter in the 519 version of PROSTAR (UNIX and Windows). The problems should be resolved in the 520 version.

Yes, I know but the version 520 is not available for WIN2000. So what can I do??

perhaps try the cgns export option?

As Kevin replied, there are problems with Ensight export in 519, but 518 should work. Your problem looks more like a "real problem", that scalar 4 is actually not on the data file. Are you able to load it with "getc conc 4"?

By the way, I think there is a beta release for Prostar 520 for Win to be released soon.

No ,it's not possible to load the concentration with getc conc 4. I guess it is similar to the Total Pressure bug for incompressible flows where the message "Error Temperature not stored on post file" appears.
