Error in importing STL file
 

Hi,

I have an assembly drawing in Catia, as per standard procedure, I converted the assembly into a single part drawing and exported as STL.

I imported this STL in Converge, the import was successful, however the following error was flashed in message log

ERROR: Error parsing STL input line OLID

What does this error mean and its resolution.

Here is the full message log:

Are you getting this error in Converge Studio or when you run the Converge solver?

I'm getting the error in the Converge studio, its the first message as soon as i import the STL file.

An ASCII STL file must begin with the line

solid name

The string name is optional. If name is omitted then there must be a space after solid. Can you check to make sure your STL file has this line?

From the error message it looks like the s in solid is missing in the file.

It has the said "solid name" initialisation, following are a few lines from the beginning of the file for your kind perusal..

I am not sure what the issue could be. The error points to the first line of the file but everything looks okay. What version of Studio are you using?

You can reach out to us at support@convergecfd.com (US); supportEU@convergecfd.com (EU) or support.in@convergecfd.com (India). We would be happy to take a look at your file and resolve the issue

Thank you
