I‘m now simulating the fuel-liquid two-phase circulation in vertical pipe. I've created UDF together with modify operate and diffusivity functionality. When i loaded the modify operate, the case might be calculated.Nevertheless, when i extra the diffusivity operate, the error appeared as demonstrated beneath:

In fact, what different types of UDF you might be working with? May very well be I can help you out. You may share your UDF then I'll have a look.

The write-up describes the experiment of h2o evaporation from fibrous materials (cotton). The material is positioned during the tube and sizzling air flows by (means of drying).

Error Object: #f" . Am really fixing melting, evaporation and reaction challenge at the same time which i can offer extra particulars in case you wanna know additional. Your contribution will be A lot appreciated. Thank you

ResearchGate's Q&A Discussion board is in which you request technical thoughts and obtain answers from experts in the discipline.

I do not know if possible in your scenario, but attempt functioning your dilemma without UDF initially, So that you will be absolutely sure if the issue is due to the UDF or not.

I'm dealing with DPM and utilizing UDF. With no UDF my product is Doing the job excellent. Once i compiled my UDF I got a warning (picture connected) but opened the file. Soon after compilation Once i run the simulation, it stopped with n deadly signal error. Here's my UDF

I do think my error arrived for the reason that I established a contour as certainly one of my Option animations and, authorized fluent to save a file for every iteration.

Drawing on 30+ several years of furnishing Engineering Gain to our ANSYS community, customers of our technical staff members have created a number of thirty moment on the web webinars. The goal is usually to help our customers get quite possibly the most of their application investment decision as a result of:

In ANSYS FLUENT, I must introduce a drag coefficient method by UDF. My issue is, " Laptop or computer language like C++, Fortran, etc is essential to jot down a system, make an ideal file after which hook it with Fluent ?"

Is there any basic strategy to introduce a whole new method in ANSYS FLUENT ? I am NOT superior in C++ language... You should help and information..

After i applied magnetic subject for cold stream (combustion model is off), the situation converged without any error. And After i turned off magnetic issue the combustion is converged. In other term, but I can't Blend each of these.

The UDF is introduced below, i couldn't uncover The rationale with the mistake for many years. Could anyone do me a favor? Thanks a great deal!!!

Temperature of air is measured by thermocouple. The textile represents porous medium with specified degree of water (wet textile). Porous layer helps make force fall when airflow sta...

After a handful of hundred iterations the CL,CD and CM displays converge And do not modify in the slightest degree anymore. I was asking yourself if that is a false Answer or if it is suitable.

Fluent saved quite a few animation you could try these out situation documents inside the requisite fluent directory. I could see detailed progress in the course of my simulation but, soon bumped into the above mentioned mistake.

Are you employing an UDF? This kind of error information shows up only when you are trying to entry some internal variables of FLUENT solver while in the UDF which aren't actually available with the respective macro schedule software.

I've encountered this when jogging a simulation on ansys fluent. the next are the exact text.
