    Importing form Proengineer to Ansys and or Comsol

    but if one shouldn't import a .prt file why there is an import pro/e part files in both comsol and ansys... thanx again.

    Importing form Proengineer to Ansys and or Comsol

    i want to import a designed geometry to ansys or comsol from proengineer but i can't. (ProE Filetype:*.prt) in ansys: it gets no error but continues processing and becomes not responding... in comsol: it says" Internal error translating CAD model Output file could not be saved"...

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    the problem is : the fluid with 5atm pressure and -50C flows through the pipe , the pipe is heated by heaters on its side and has constant temp 200C. i want to find the required length to have fluid with 100C.

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    the pipe is like this.. i don't work in work bench i just create its geometry in workbench. but i do other analizes in ANSYS .

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    its 3D analize because it has a wavy shape (it's not straight) so i can't do it axis symmetric.. i create 3D pipe geometry in ansys workbench and i import it in ansys. but i can't mesh it with element "FLUID116" ... with witch element i can mesh instead?? tanx

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    ok but how i can calculate film coefficient from nusselt? i am using fluid116... and has N1...N4 input. can i change its options to change required inputs? tanx...

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    hi minger but all i have is nusselt, prandtl and reynolds numbers... so i have 3 known factors but 4 unknown: N1,N2,N3 and N4. it has not a unique solo...

    How to Calculate Nusselt Number for Air Flow in a Pipe with ANSYS?

    Hi i need to calculate nusselt number for stimulation of air flow in a pipe with 5mm diameter and the pressure is 5atm. it should be in the form: Nu = N1 + N2 Re^N3*Pr^N4 and i want to calculate N1,N2,N3,N4. but i don't know how? can anyone Help?
