I‘m now simulating the fuel-liquid two-section flow in vertical pipe. I've published UDF which includes adjust purpose and diffusivity operate. Once i loaded the change function, the situation is often calculated.On the other hand, as soon as i additional the diffusivity function, the error appeared as proven beneath:
Potential subject areas will be determined by your suggestions, so be sure to allow us to understand what you would like to check out!
I really should point out that the combustion with MHD equation was solved with no Lorenz Pressure and Joule Heating, but as I turned on Lorenz force the answer approach stopped Performing (with b_0 Scale component of 0.one).
I am working on Windows 7 and beginning fluent in parallel. At the time it truly is started out I have it read through a journal file which sets up the right configurations after which proceeds to a do loop. This do loop runs one time action after which you can create to the Command file. This will work by itself.
My project is temperature Investigation of the double pipe helical kind heat exchanger working with h2o as fluid.
I do not know if at all possible in your case, but test operating your dilemma devoid of UDF very first, So that you'll be positive if the problem is due to UDF or not.
I am working with DPM and working with UDF. Without UDF my product is Functioning superior. When I compiled my UDF I received a warning (image attached) but opened the file. After compilation when I run the simulation, it stopped with n fatal sign mistake. Here is my UDF
I believe my mistake came because I set a contour as certainly one of my solution animations and, permitted fluent to save a file For each iteration.
I'm engaged on a flame afflicted by exterior magnetic area employing MHD module with fluent fourteen.five . I'm applying compiled UDF to provide non-uniform profile for boundary issue. My options are:
Talk to someone to modify you model and UDF if It is your very first time to cope with stage adjust or meet up with this dialog.
I solved this problem by reinstalling ANSYS. I bought a clean copy within the consultant in Center East and Africa as my college has an academic license and I ended obtaining the trouble.
After i utilized magnetic discipline for chilly circulation (combustion model is off), the trouble converged without any mistake. And After i turned off magnetic challenge the combustion is converged. In other word, but I can't Mix both of them.
it not easy to say about this mistake because this is available in the vast majority of cases when their is some mistake so i proposed you that you should undergo fluent guide and check out to figure out you error. you might adhere to my before publish Which may be help you.
Good day Saidul, desire i could possibly be of fantastic help with regards to your UDF. I will nevertheless tips that before you decide to Develop, load the functionality And at last hook the UDF, you fish out each mistake in C file.
Following a couple of hundred iterations the CL,CD and CM screens converge And do not improve in any respect any more. I had been questioning if this is a Fake Resolution or if it is appropriate.
Fluent saved various animation circumstance documents inside the requisite fluent Listing. I could her latest blog see comprehensive progress through my simulation but, quickly bumped into the above talked about error.
I am endeavoring to solve the movement in excess of a circulation controlled aerofoil employing Ansys FLUENT, (making use of SA turbulence model) and I've seen that if I would like to lessen y+ to the lessen price, the continuity residual will minimize as much as an get of ten^-four and then it will eventually a little bit oscilate forever.
I was in a position to get this to operate in serial so I believe it has some thing to complete with running fluent in parallel but I don't learn how to take care of it.
