Dear all,
I'm doing fluid-structure interaction analysis on pipe to observe the response of pipe and the flow pass through the pipe. I use CFX and transient structural to simulate it for 20seconds. After some iterations (around 5s), error occurs: *** WARNING *** SUPPRESSED MESSAGE CP = 21474.225 TIME= 20:29:51 Material number 2 (used by element 12900 ) should normally have at least one MP or one TB type command associated with it. Output of energy by material may not be available. *** WARNING *** SUPPRESSED MESSAGE CP = 21483.240 TIME= 20:30:26 Material number 2 (used by element 12900 ) should normally have at least one MP or one TB type command associated with it. Output of energy by material may not be available. *** WARNING *** SUPPRESSED MESSAGE CP = 21491.695 TIME= 20:31:00 Material number 2 (used by element 12900 ) should normally have at least one MP or one TB type command associated with it. Output of energy by material may not be available. *** ERROR *** SUPPRESSED MESSAGE CP = 21500.697 TIME= 20:31:55 An unexpected error ( SIG$SEGV ) has occurred... ANSYS internal data has been corrupted. ANSYS is unable to recover and will terminate. Previously saved files are unaffected. Please send the data leading to this operation to your technical support provider, as this will allow ANSYS, Inc to improve the program. For the CFX part, it sounds: +--------------------------------------------------------------------+ | ERROR #002100061 has occurred in subroutine SERVE_CLIENTS. | | Message: | | The connection between this CFX process and an external process | | has died unexpectedly. The following error was received: | | External process : ANSYS | | Error experienced : Read | | | | ** This error is fatal: Terminating ANSYS CFX Solver execution ** | | Please review the output, error and log files from both the CFX | | and external processes to determine the cause of the error. | +--------------------------------------------------------------------+ I try to change the mesh and step size but it can't work also. Is there anyone who could give advice on this matter? Thank you and have a nice day. best regards, kqlee |
