Error initial file

Hello there,
I'm currently facing a problem using a .res-file to initialize my simulation. The two simulations use the same mesh and same BC's - all I've changed is the advection scheme and turbulence numerics from a first order to a second order scheme. After interpolating the initial values, partitionating, checking the mesh and processing my variables/monitor points, I receive these errors before the solver should start to iterate: ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | io_gunzip: Data error ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | io_gunzip: decompressed too little data: got 0 bytes, expected 24- | | 0000 ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | read_compressed_dataarray: decompression failed ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | iocnt: read data failed ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | ReadLong: read data failed: what=G/VEL_FL2 where=ZN1/VX ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine ReadLong I'm working with Ansys 17.2 CFX. Thanks, Eric |

It appears the res file has been corrupted. I would rerun the initial run to regenerate the initial conditions and try again.

I tried that already and still receive the same error. The out file of the initial solution looks good. Also giving the solver some more memory didn't solve the problem.

Then I suspect the initial def file is corrupted and I would regenerate that in CFX-Pre and try again. Something appears to be corrupting the res file from the initial run.

Why don't you load the results-file into the Solver manager. There you can change the settings and then continue the calculation by pressing the triangular button (Restart the current completed run).
In other words, you don't need a def-file nor perform a interpolation, etc. |

Seems like you're right. I just checked the results of the initial solution in post and discovered that the velocity can't be plotted in any regions/surfaces. This could be the reason why initializing failes. This is the warning:
WARNING 'Vertex' values for Variable 'Water.Velocity' do not exist on Geometry /DATA READER/CASE:Case CFX 9/BOUNDARY:Inlet_Water_1. When I change the velocity component (u, v, w), also the min/max values of the range change - so the results for the velocity field must be written somewhere. Do you have an idea why they can't be plotted? In output control (CFX pre), the result is set as standard. |
