Hello, I have a question for you. Can you explain about "vel[0] = - 0.25 * sin(t); vel[1] = 0.25 * cos(2*t); omega[2] = 10*cos(3*t);" in your script? What do these mean?
One question pls, why did you separate the boundary layer at 5:25 ? my guess is that youdon't want to apply dynamic mesh remeshing, layering and smoothing on the boundary layer zone, but only apply the remeshing on the tetrahedral/triangular cells of the fluid zone pls correct me if I am wrong Thanks!
Yes, but if you do, you can only get the domain to move accordingly to the forces being exerted on it by the surrounding fluid. If you wanna supply some external force or torque or define the motion of the body with an equation, you need a UDF.
Greetings, thank you, it was very helpful, unfortunately when I try to compile the .c code, in the console apears an error message and I'm unable to know what is causing it, I really will appreciate your help In file included from udf_names.c:3: C:\PROGRA~1\ANSYSI~1\v212\fluent\fluent21.2.0\src\udf\udf.h(79,12): fatal error: 'ud_io1.h' file not found # include "ud_io1.h" ^~~~~~~~~~ 1 warning and 1 error generated. scons: * [udf_names.obj] Error 1 scons: building terminated because of errors.

Best video on dynamic meshing by far ❤
This song is sooo similar to "Meskie Granie - Poczatek"
Thanks for the tutorial

I keep getting negative cell volumes stopping me from running this, would you have any idea why?
Sir please make a video of spraying nozzle move in translation motion
i want to fix my mesh in horizontal direction and allow free to move in vertical direction , how this is possible
Where can I get the UDFCase124.c file? Thank you!
Read the description.
I followed your udf and all the steps but console shows
Warning: incorrect cg motion UDF functionname:: libduf on zone 6
I've got "floating point exception" error
i have the same problem as well
hye, can you explain about the coding.
How can I display simulation results as well as time on graph in animation?
i really loved your video. can u make a video tutorial on undulating fin in water?
Can u give a tutorial how PIG move in pipe please??
Can we apply dynamic mesh without udf ?
Yes, but if you do, you can only get the domain to move accordingly to the forces being exerted on it by the surrounding fluid. If you wanna supply some external force or torque or define the motion of the body with an equation, you need a UDF.

Same for me. Idk If we shouldn't just prepare an additional .h file just with the headers...
same error here, have you guys found a fix for it?
