Fluent automatically switched to parallel mode

rahulmule797@gmail.com · November 5, 2019, 00:48

Hello everyone, I am starting fluent in serial mode but it is getting started in parallel mode. I don't know why this is happening so the udf I am using in my problem is not doing the intended function. Any immediate help is appreciated. I'm also shared the warning is shows on fluent launch.

***********************************************
Info: Your license enables 4 way parallel execution.
For faster simulations, please start the application with the appropriate parallel options.

When I'm trying to interpret the UDF it is showing warning as below:
***********************************************
*
**WARNING:Automatically switched to run in parallel -t1 mode. **
**Detected non- Paralleized UDF usage, enabling parallel usage. **
**If you encounter any issues, please re-run with -t0 flag. **
***********************************************

Thanks in advance..

Reduce the "Processes" to "0" in launcher or Start fluent using "fluent 3d -t0" in cmd.exe console

Thanks for reply..
I tried by reducing processes to zero but in that case udf is not doing intended function.
I'll check it by starting using "fluent 3d -t0" In cmd.exe in console.
