I‘m now simulating the gas-liquid two-stage flow in vertical pipe. I have created UDF which include modify functionality and diffusivity function. When i loaded the alter functionality, the situation may be calculated.On the other hand, after i extra the diffusivity functionality, the error appeared as shown below:
Long term subjects will probably be based on your feedback, so be sure to let us know very well what you desire to to find out!
I should really point out that the combustion with MHD equation was solved with no Lorenz Power and Joule Heating, but as I turned on Lorenz force the answer method stopped Doing work (with b_0 Scale issue of 0.one).
I'm focusing on Windows seven and commencing fluent in parallel. The moment it is actually begun I've it examine a journal file which sets up the suitable settings after which proceeds to some do loop. This do loop operates 1 time step and then compose to a control file. This functions by by itself.
My project is temperature Examination of a double pipe helical style warmth exchanger making use of drinking water as fluid.
I don't know if possible with your circumstance, but try working your challenge without the need of UDF initial, So that you'll be certain if the situation is because of the UDF or not.
I am dealing with DPM and making use of UDF. Without UDF my model is Doing the job very good. Once i compiled my UDF I got a warning (image attached) but opened the file. Immediately after compilation After i operate the simulation, it stopped with n deadly signal error. Here's my UDF
I believe my mistake came simply because I established a contour as one among my Answer animations and, authorized fluent to save a file For each and every iteration.
I'm engaged on a flame affected by external magnetic area working with MHD module with fluent fourteen.five . I'm using compiled UDF to provide non-uniform profile for boundary issue. My configurations are:
Talk to somebody to modify you model and UDF if It really is your 1st time to manage period transform or fulfill this dialog.
Is there any uncomplicated system to introduce a different you can try these out method in ANSYS FLUENT ? I am NOT superior in C++ language... Be sure to help and information..
When I utilized magnetic area for chilly movement (combustion design is off), the trouble converged with none mistake. And when I turned off magnetic challenge the combustion is converged. In other word, but I are unable to Mix both of those of them.
it not easy to say relating to this mistake for the reason that this is available in the majority of the circumstances when their is some error so i suggested you that be sure to experience fluent guide and try to determine you oversight. it's possible you'll observe my previously publish Which may be help you.
Good day Saidul, desire i could possibly be of fantastic help with regards to your UDF. I will however information that before you decide to Develop, load the functionality And at last hook the UDF, you fish out every error in C file.
Am not truly utilizing UDF in my circumstance. Am solving a difficulty which involves melting, evaporation and gasoline period response. I've enabled multiphase VOF, soften & solidification and species transportation.
Fluent saved numerous animation circumstance documents while in the requisite fluent directory. I could see step-by-step progress throughout my simulation but, before long bumped into the above stated error.
I am wanting to clear up the flow above a circulation managed aerofoil applying Ansys FLUENT, (utilizing SA turbulence model) and I have discovered that if I would like to lower y+ to a reduce worth, the continuity residual will lower as many as an buy of ten^-4 and then it is going to somewhat oscilate eternally.
I used to be capable of get this to work in serial so I think it has something to complete with operating fluent in parallel but I don't learn how to deal with it.
