Q. I submitted an FSI analysis using FLOTRAN and ANSYS. The case appears to run correctly but the analysis terminates with messages "Missing parameter= ." and " Undefined parameter used as boundary condition.". I reproduced the error on release 10.0 and 11.0.
A. This is due to a bug in the MFS setup with FLOTRAN. The workaround is to reverse the order of the field solutions. Since the problem you submit is essentially driven by the solid, the first FLOTRAN solution is essentially a trivial one. But it doesn't hurt anything and takes little time.
