Hello I'm very new to Ansys 14 software, while dealing with turbo-machinery in solving the CFX tutorial no-25( centrifugal compressor aerodynamic and structural analysis)
I used Angular Velocity:- 5000 RPM Mass flow rate: - 0.53 kg.S^-1 Physical TimeScale:- 0.0002 S. the CFX solver always returned------------ OUTER LOOP ITERATION = 132 ( 32) CPU SECONDS = 2.936E+03 (8.426E+02) ---------------------------------------------------------------------- | Equation | Rate | RMS Res | Max Res | Linear Solution | +----------------------+------+---------+---------+------------------+ | U-Mom | 0.99 | 3.8E-04 | 4.7E-03 | 5.4E-04 OK| | V-Mom | 0.98 | 5.1E-04 | 5.3E-03 | 4.2E-04 OK| | W-Mom | 0.99 | 2.6E-04 | 5.6E-03 | 6.1E-03 OK| | P-Mass | 0.92 | 1.3E-01 | 1.2E+01 | 5.3 2.7E-05 OK| +----------------------+------+---------+---------+------------------+ | H-Energy | 0.99 | 1.2E-03 | 1.9E-02 | 5.3E-04 OK| | T-Energy | 1.01 | 3.6E-05 | 1.3E-04 | 5.9 5.3E-04 OK| +----------------------+------+---------+---------+------------------+ | K-TurbKE | 0.98 | 3.7E-04 | 5.9E-03 | 5.8 1.8E-04 OK| | E-Diss.K | 1.00 | 5.1E-04 | 2.6E-02 | 8.4 6.3E-05 OK| +----------------------+------+---------+---------+------------------+ +--------------------------------------------------------------------+ | Notice: The maximum Mach number is 1.090E+03. | +--------------------------------------------------------------------+ ================================================== ==================== OUTER LOOP ITERATION = 133 ( 33) CPU SECONDS = 2.964E+03 (8.702E+02) ---------------------------------------------------------------------- | Equation | Rate | RMS Res | Max Res | Linear Solution | +----------------------+------+---------+---------+------------------+ | U-Mom | 0.99 | 3.8E-04 | 5.0E-03 | 5.3E-04 OK| | V-Mom | 0.98 | 5.0E-04 | 5.2E-03 | 4.2E-04 OK| | W-Mom | 0.99 | 2.6E-04 | 5.5E-03 | 6.1E-03 OK| | P-Mass | 1.07 | 1.4E-01 | 1.2E+01 | 5.3 2.7E-05 OK| +----------------------+------+---------+---------+------------------+ | H-Energy | 0.99 | 1.2E-03 | 1.8E-02 | 5.5E-04 OK| | T-Energy | 1.01 | 3.6E-05 | 1.3E-04 | 5.9 5.5E-04 OK| +----------------------+------+---------+---------+------------------+ | K-TurbKE | 0.99 | 3.7E-04 | 5.9E-03 | 5.8 1.7E-04 OK| | E-Diss.K | 1.01 | 5.2E-04 | 2.9E-02 | 8.4 6.4E-05 OK| +----------------------+------+---------+---------+------------------+ +--------------------------------------------------------------------+ | Notice: The maximum Mach number is 1.144E+03. | +--------------------------------------------------------------------+ ================================================== ==================== OUTER LOOP ITERATION = 134 ( 34) CPU SECONDS = 2.989E+03 (8.952E+02) ---------------------------------------------------------------------- | Equation | Rate | RMS Res | Max Res | Linear Solution | +----------------------+------+---------+---------+------------------+ +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Floating point exception: Overflow | | | | | | | | | | | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine FPX: C_FPX_HANDLER | | | | | | | | | | | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | An error has occurred in cfx5solve: | | | | The ANSYS CFX solver exited with return code 1.
