I’m using OF 1906 and CalculiX v 2.15.

The precice library is: libprecice.so.2.0.0

and I call for it in controlDict with the command:

```
functions
{
preCICE_Adapter
{
type preciceAdapterFunctionObject;
libs ("libpreciceAdapterFunctionObject.so");
}
}
```

It is very strange, because in order to avoid mistake I used the same structure of the flap behind the cylinder, but the OF participant doesn’t start at all.

The error message is:

```
