Mesh deformation problem in CFX 15.0
Hello, everyone I am studying cfd.
first my english is not good please understand me. I have to solve a stage of axial compressor. (including rotor and stator) it has two domains. one is a rotor another is stator. I want to solve FSI simulation. so these domain were applied mesh deformation option. In case of CFX 14.5 solver -> it is not problem. but in case of CFX 15.0 -> this simulation have a error message. Details of error:- ---------------- Error detected by routine MAKLNK COLDNM = MAXCLOOP CNEWNM = MAXSTEP CRESLT = OLD Current Directory : /FLOW/ALGORITHM/CONTROL/MESHDISP_CLASS/TRANS +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine MEMERR | | | | | | | | | | | +--------------------------------------------------------------------+ CFX 14.5. and CFX 15.0 has a same condition. why they are different???? |
I am not sure if you are still struggling with this, but for anyone with this same issue, it is a confirmed bug in R15. It happens when there are multiple boides in an FSI simulation with a moving mesh. The work around is to use R14.5 or wait for R16 as the ansys rep that I talked to said that R16 does not have this issue.

I am also getting same error with CFX15.0 has anyone found out the solution to the problem

I think Kevin's post explains exactly what is going on.

Thank you very much for your reply.
I am now trying same def file to run on CFX16.0 but now I am getting different error. ---------------------------------- Error in subroutine GET_VARVX : OLD : Failure to get data area USER_AV89_FL1 GETVAR originally called by subroutine SU_DVAR_ZONE +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine GV_ERROR | +--------------------------------------------------------------------+ Is this error because of some variable related to area. because below are the list of expressions I am placing, i am not able to find any error in that. I think you can help me out to deal with this.
