I'm using ANSYS 19.2 academic version. I'm simulating disk sprayer with wall UDF.

I use the code directly from fluent UDF manual.

I compiled using VS 2017 prompt.

No problem in the initialization step.

But when I run calculation it displays the following error.

""No error handler available

 

Error: Cortex received a fatal signal (unrecognized signal).

 

Error Object: ()""

Anything else in the TUI?  If you copied the code directly from the manual check for white space characters, HTML tends to be full of them.

Thanks rwoolhou.

I have the same problem. nANSYS 19.2, VS 2012, well-ran UDFs from other computersnget n''Error: Cortex received a fatal signal (unrecognized signal).nError Object: ()nnError: %cx-set-label: wta[1](widget)nError Object: #f''nwhen I hit the calculationnAny help would be appreciated.n

What does the UDF do? Widgets are the terms used for the GUI panels. n

nDid you compile the code on the current computer?n

[Darry6682]

Thanks for your attention! I ran the fluent 15.0 before but it happened to stall at the first iteration (as shown in the figure below)when I hit the calculation last week (before that I could run my case fluently). So I supposed that the version I use is quite low or the computer is overloaded and therefore I installed the Ansys 19.2 and simplified the mesh elements from 240w to 150w. However, the case in fluent 19.2 has not been successfully run once.nI load three UDF in this case. One is to improve the K-e model and provide sheared wind profile and another two are to model the wind turbine with VBM (virtual blade model).I didn't compile the code on the current computer and just compiled them in fluent. Again, this setting has been successfully run on my old version of fluent, it just happened to stall one day.nnThanks for your help. Darry

yes, of course. Here it is.nnDEFINE_ADJUST(SrcComp,domain)n/*

what was the last message printed before the error?n

[Darry6682]

the last message indicates that I have loaded the VBM model successfully.

[DrAmine]

Do you the compiled VBM UDF library only? Or the Source too?n

[Darry6682]

Yes, I have the source in the libudf too. The libudf folder has two folders, namely src and win64.
