Step-by-Step Tutorial: Homework of Session 1


#42

Okay, perfect! Thanks!


#43

Cant find any progress even after 30mins into Operation 1 meshing. Can any one help? (i’m using a pretty good internet connection)


#44

Can somebody help me to understand the error I am getting. Please find attached picture


#45

Though I chose faces in surface mesh refinement , this error is poping up!
Please help me with this


#46

Hi @npotabatti,

did you counter-check your settings? I will start the simulations tomorrow morning myself to see if there is any inconvenience.

If you still cannot manage to make it work I will look into your project.

Enjoy your weekend!

Hi @mashko_Or,

did it work so far? Or do you have still problems with your meshing operation?


#48

I will try that once i reach home. Sorry for late reply.


#49

Yeah I cross checked those mesh refinements! Can you just go through my project?
Thanking you for support!


#50

Sir, i have redone the meshes by selecting faces as you had stated.But the problem still seems to persist.I keep getting the error at 6deg simulation

Just to be sure I even setup the simulation from scratch.Here is a snapshot of the solver log before termination.


#51

I am having a problem while performing the meshing operation for the 6degree model. Every time it got stuck with the same error. I performed the meshing operation from scratch also, still getting nothing but the same error. Help guys…

HI,
My simulation stopped at 450 iterations and i got the email that it was completed even though i set it for 1500 also none of the force plots were there.Please help


#53

Hi @npotabatti,

make sure you post the public link for your project here so everybody can have access to it. I will check that. Probably wrong values for k and omega which may lead to numerical instabilities.

Cheers,

Jousef

Hi @debroy84863568 & @sikkasehdev ,

make sure to post your project link here so that I can have a look at it. I will check that for you.

Best,

Jousef

I wanted to know following. We are creating prismlayers on the street in order to calculate the boundary layer. My question is, would it not be better to make the street a moving wall in order to save soma elements and use them somewhere else?


#56

approximately how much time will it take for my account to get converted from professional account to a public account. Also I had started the simulation and then received the ‘run may cross your quota’ error so will it affect the simulation as in will i have to redo the simulation again?


#57

HI,
My project link is mentioned below, Can anyone please tell me why the iterations stop at 450 every time even though they are set for 1500,is it some glitch?

Hi @sikkasehdev,

please counter-check your mesh settings. Your region with small elements is way too big thus drastically increasing computation time.

Adapt your settings and rerun your simulation. It should work then.

P.S.: Please give your mesh regions meaningful names not just “Mesh Refinement X”.

Best,

Jousef

Hi @bmaitra,

did you already read the post by @ahmedhussain18?

If you already sent an Email you will probably have to wait a bit.

Also consider the post from @AnnaFless : Exceeding computational quota

Best,

Jousef


#60

Hello will the homework completes if we finishned meshing and simulation part,and viewing post processing results of 2,3 different angles ?


#61

Hello!!!
I started all 8 mesh generations, with small in-between time and for 3 hours I had no result. I started just one and proceeds well. Any insight why that happened?
Thanks in advance! :slight_smile:
