SubscriberHi everyone,
I am doing a simulation in fluent(including a UDF), everything is ok on my personal computer, but when I put the case on HPC(1 node with 128 processes), once I initialized it, the error popped out.
Some information about settings:
1.UDF is included, but the UDF can be successfully compiled and loaded on HPC;
2.Mesh number: about 1.5 million
3.k-e model and mutiphase(2 phase, oil to vapor, cavitation)
4. Ansys verion 2021R1
Details about the errors are shown in the Figure 1, 2 and 3.
 I have no idea what causes this, and how to solve it?
Regards

Ansys EmployeeAre you running interactively with GUI or batch?
What happen if you try to run with fewer cores?
How many cores are you using on your machine that runs? -
