POLYFLOW : The motion of the impeller is wrong (MST calculation)
When running a MST calculation, the impeller undergoes a wrong motion.
The parameters defining the impeller motion may be wrong, and have to be checked.
If the calculation starts from a previous result file that already invokes the MST features, the information read in that result file will be used. The information may have to be checked. It includes translation velocity, rotation velocity and rotation axis as well. The user should keep in mind that angular velocity is given in [rpm].
In general, the motion can be checked by invoking POLYFLOW with the option -motion as follows:
polyflow -motion < data_file > listing_file ...
This option actually skips all solvers.
