Hi all


I'm trying to simulate FSI problem. i have to different operating systems in two computers. i always do some works such as drawing geometry, meshing, define bondary condition in cfx pre,... in Ansys 12.1 on Windows operating system. then i copy .def and ds.dat files to other computer with Linux operating system. i use Ansys 12.1 on Linux and in this computer i can't access to ansys GUI, i have to use command. i find that i have to addressing ds.dat file again in second machine. How can i do without GUI of CFX?

Best regards.

Are you asking how to start an FSI simulation from the command line?
I normally use:
cfx5solve -def asd.def -mfx-run-mode "Start ANSYS and CFX" -ansys-input asd.dat
where asd.def and asd.dat are your cfx and mechanical files.

Thanks for reply Lance

No. In CFX-Pre the location of ansys input file must be specify in:
Analysis type\external solver coupling\ ansys input.
When i copy the .def and .dat file from my first machine to second machine, the new location of .dat file in second machine(Linux OS) most specify, but i don't know how can i do this without CFX-Pre GUI. How can i do?

Best regards.

The path in CFX-Pre doesn't matter when starting the solver. In the Solver Manager or on the command line the path to ds.dat is set and this is what gets used.

The path of ds.dat file is important, you can test it, cut .def and .dat files in another directory an run solver. first error is about location of .dat file because of in CFX-pre previous path was saved for ds.dat file.
How can i set new path for ds.dat file in second machine?

Are you sure you don't have a windows file path in there? I can see that it wouldn't get parsed correctly and could cause an error. In any case, without GUI access use the cfx5cmds command to pull the CCL into a text file and edit it. See the doc.

Hi Guys,

I know this is an old thread but I'm pretty desperate and was hoping that I might be able to find some help here as the thread seems to be related to my problem.
I'm doing my final year thesis on an FSI model using Ansys CFX and Ansys mechanical (19.2). My problem is I cannot get the model to run on the HPC which uses Linux. I was wondering if anyone has or knows of the correct script?

I have the .def and .inp files but I just can't figure out the correct script to tie it altogether in Linux.
