Hi,
I am trying to do a 2D analysis of a wing structure of aircraft. The wing structure itself is a cross-flow fan with a modified housing. I have set environmental variable CFX2D_Mesh=1. For now i am trying only a simple bounding box. I created rectangular domain with 2400x1600 dimensions and 3mm thickness. I have given inlet with velocity, outlet as opening with 0 static pressure. upper and lower surfaces as walls with free slip. two side faces as periodic boundary pair. mesh edge length=3mm(which is thickness) so that only one element thick mesh is produced. I tried with more and less values for mesh edge length as well and i get the same error as below. i could generate surface mesh but when i say write def problem starts. I couldnt write the definition file after the creation of mesh. it gives error like this: --------------------------------------------------- Error reported from application CFX-Build 5 Error during the creation of the Definition File. openfile: the file cfx5.def is being locked or the wrong lock file cfx5.def.lck exists iocnt: open the primary file failed Call to IOCNTF failed from DEFCTL! Action requested was OPEN. IERR = 21 STOP called from routine DEFCTL ----------------------------------------------------- Can pls somebody tell me what this is.. I am not able to understand or make out anything. Thanks in advance. Deepthi. |
