initial file for fsi modeling?
i want to run a fsi model...this error appears in ansys out file and the run stops in the first itterations:"one or more element become highly distorted...."
now i want to change the initial condition in cfx to solve this problem...i decided to solve a transient rigid model and put the results as the initial file .res for the fsi model...but for adjusting the time i encounter a problem...i mean the rigid model starts at t=0 and ends at the time .82 which is the total time(pulse period) for fsi model.if i set the total time for fsi model as 1.64 and the coupling initial time =.82 then this warninig appears:
"The simulation time value obtained from the CFX input file is inconsistent with the Coupling Initial Time value used for this simulation. Please review results carefully.
CFX input file time : 8.2-01
Coupling Initial Time : 0.0000E+00
what can i do and is this a useful wal to solve the fsi problem?
