Hello, I see a new version of preCICE, so I updated preCICE-3.1.2, I 'm sure my openfoam can calculate the problem normally, and my calculix-adapter can connect to preCICE. I used openfoam-adapter-v1.3.1, but when I tested an official example, such as elastic-tube-3d, I had the following problems :

I suspect that my openfoam-adapter is not connected to the preCICE, but I compiled appeared ok, successful words, I know how to solve this problem, I need everyone 's help, thanks

It’s the first time I see such an error. From the logs, this does not seem to be related (at least not directly) to the adapter.

Also, I only know SHA1 as a hashing algorithm, not sure where this comes from… 😕

I don’t know if looking at the code could give you any clues:

Anything special about this system or this OpenFOAM installation?
