So, here is an update. I ran calculation after refining that particular cell region which increased density which I do undestand is better momentum transfer. The calculation ran only a few 1000 iterations overnight due to the size of the mesh but the initial results seem to be positive.
Here are velocity streamlines. I’ve displayed the plane 1.5m for better understanding. Consider a horizontal line from beneath the hub(on this 1.5m plane) to the tip, it is lesser at first then increases a bit and then decreases. Just how I said it should be.
This is how they previously were, direct decrease :
I must add this is in very preliminary stages and the simulation is running. I’ll give the next update 10-20hrs from now.
What do you think?
”you can bring the upper position down towards the monitor plane. We routinely run 50-100M cells meshes so you’re fine. Assuming you have the hardware”. After creating the first cell region and refining it, I clicked on refine again out of curiosity and then fluent closed automatically with memory reallocation error which I think is regarding the cores. I’m running currently on an intel i-7 processor with 12 cores. I’m afraid this is all I can manage for now(its from my university). Also even if I make a smaller adaption region I believe it will still run out of memory.
How is this idea though, Initially the mesh was at 280mm size, I bring it up to to say 500mm or 580mm which was default and then multiple adaptive adaptive refinement in the region of interest? This could ensure cells are placed where we need them to be placed.
The issue is that this is going to go for 3d printing in a matter of days and I can’t have my values way off the experimental ones. An error of 15-20% would still be acceptable.
Please reply. I’m grateful for your assistance.
