Hi Hxd,

The model as likely went unstable during runtime. There are a few things you can try:
- Lowering the stability factor
- Increasing my meshing
- Replacing any absr BCs to impd.

Here is a post detailing the differences in BCs it should be as simple as this to make the change:
```
c old code
boun 
    side xmin absr
c new code

    side xmin impd auto
```
