Hello Friends,

I'm trying to use the pt_erosion.F supplied by Ansys in ...CFX/examples/UserFortran to customize the erosion model; however, even after loading the pt_erosion.ccl (provided by Ansys in the same directory), the solver crashes. I have compiled the pt_erosion.F with Intel Fortran 10.1 running on IA-32 and the pt_erosion.dll gets generated. So I don't really know what the problem is. It would be greatly appreciated if you can send me some insights into this. the solver error message is:

Hey,

were you able to resolve this issue?

Thanks

Hello,
the subroutine name must be LOWERCASE in ccl but UPPERCASE in fortran code. Strange, undocumented but that's fact. It is one of the issues when compiling with Mingw's gfortran, as this compiles all subroutine names to lowercase.
See: http://www.cfd-online.com/Forums/cfx...nnt_amd64.html

hello my friend, I come up with the same trouble like you（forgive my suck English, I'm from China）.I build a particle user routain and everything seems well until I run the CFX solver,then the problem report appears.Have you figured it out?or anybody who can help me!!!!Very Very appreciate

Creation of dll does not mean it is going to work. ;-(
Input files seem to be correct.
Most common mistake: path to dll wrong: Where does the given "Library Path = .." really point to?
Try a full path to the dll in ccl or CFX-UI first. Later try to adjust to relative path (might differ if CFX is run standalone or from workbench).
If this doesn't help:
Compilation with "cfx5mkext"?
Architectures fit?
Precision settings fit (single, double) in compilaton and solver run?
