Solving Problem with chtMultiRegionSimpleFoam

Hello guys!

cann somebody help me,
Iam tryng to solve a heat transfer trough multiregion Fluid and Solid, but itīs not working.
this ist the error, I cann understand what happens!

Is your problem resovled?

Hi,

Were you able to solve your problem? Even I have the same problem. Is it the problem with the version or the software?
