Can someone help me

@ Ali : Here I have compared two types of T-Junctions blocking in ICEM CFD. Models are M1 and M2. The blocking method of M2 is yours.

@EugenZ: Here is video tutorial and all other files for your reference.

PS. I was using M1 blocking method for M2 and but it turns out to be that Ali's method is better.

I'm sorry to ask you again...im following your video, and yet, whenever i do ogrid it doesnt look like yours. I tried both ways, always same problem and i dont know how to fix it.

when you create ogrid it goes all the way to the end of the face and mine doesnt, its killing me...i followed you every word and it all looks good until i get to ogrid.
THis is what i get at the end, pls help me

You got everything clearly?

Good Day Folks,

Basically what I did is by using camera to capture wing motion by frame by frame, the output is .csv file format with set of xyz data. If you see inside csv file, the 1st row gives first frame(xyz of point 1,2,3), 2nd row gives 2nd frame (xyz of point 1,2,3) similarly up to last.

I did small program in Matlab to replicate my wing. I am thinking by using these coordinates or script to make Dynamic mesh in ICEM CFD/Fluent is somewhat easy to replicate the wing with moving/dynamic mesh.

kindly see my attached image(wing), csv file & matlab program for your kind perusal. kindly help me, how I can built Dynamic/Moving mesh.

There is no change in ICEM meshing for static or dynamic analysis.

Remeshing is done by software through dynamic mesh modules.

Thanks for reply Far,

Some what I good in ICEM CFD & Fluent, I thought I have to write UDF for this problem But I don’t how to write UDF.Let me know without UDF it’s possible? Kindly guide me what I have to do?

For dynamic mesh motion, you need to write UDF.
