Hello
I am using tensorforce 0.6.0 in DRLinFluids package. I can run tutorial case in DRLinFluild on the cluster. I slightly change the openfoam case part in DRLinfluid from a cylinder of two jet variable to one. then the initialization error arise. as :

I also made comparison for the original setup and the one I modified.

can you please let me know what I can do ?

Thanks
