hello
dose anyone knows how can you change the comsol's m file to gather a pressure data from cfx(ansys) in transient running and take it back to comsol and run again?
thank you

Why would you want to do this ? This is asking for trouble and problems.
But, if you insist, even after realizing that COMSOL has a much better CFD simulation capability that will provide the data you need to produce multi-physics simulations, I am guessing you could do this by the following:
1) write the CFX data out to a file,
2) read the data in via the function capability of COMSOL
3) use the function within the COMSOL solution
4) run the entire job within a MATLAB loop that controls both the CFX and COMSOL execution
5) will probably require explicit time stepping to get all this to work; and probably will produce questionable results because of that
forewarned:
History has proven that trying to create multiphysics simulations by coupling separate codes through explicit time stepping and external data I/O (via file or memory or "ram disk") is prone to failure.

Thank you so much for your kind information
I want to ask you some questions about comsol's ability.
I'm working on cylinder underwater and I can't neglect the effect of viscosity,also the fluid is incompressible.so with this information are Comsol able to model this and get the pressure analysis information for acoustical analysis?
thank you

Yes.
