Hello!
I am running a new engine geometry case. As this is first run to check the issues in the geometry setup.
I am facing this issue of Segmentation fault (core dumped) after parallel block definition

The parallel block size (dx, dy, dz) is 2.380598e-01 7.559968e-02 1.560972e-01.
rank = 0 num_level_active[2]=26, num_level_total[2]=26
rank = 0 num_level_active[3]=89, num_level_total[3]=89
rank = 0 num_level_active[4]=363, num_level_total[4]=363
Segmentation fault (core dumped)

Could someone please guide me where the issue can be?
Thanks you!

Note: Problem has been resolved. Error was due to valve and piston interaction.

Hello and thank you for your message. The symptoms of the problem appear to be related to the surface geometry. You can use the diagnosis tool in CONVERGE Studio to check for problems with the surface. If you have moving parts, it will helpful to move your simulation to the start time (using the animation panel), and run the diagnosis from that position first to see if you have any geometry problems related to the initial configuration or moving profiles of the parts. If this doesn't help, feel free to send your case to support@convergecfd.com or report back with further diagnosis.

Best regards,
David

Hey David,
Thank you for your message. you are correct, the issue was with moving boundaries. I have resolved the issue.
Thanks again!!
