please help, error in simulation.

please provide with the spreadsheet to calculate numeric settings

It seems like you choose to wrong number of computing cores. You have to choose a 32 core machine to run this simulation.

66

I have just checked the number of computing cores, and it has been set to 32 from the begning.

Hi,

i imported the project link you posted here.

Cheers,

Thanks i missed that one, i thought it was the core chosen in the mesh setting

Hi,
I got some problems with the numerics as you can see. but i put the values as it was written in the tutorial.
Any help?

thank you very much.

@Akrem @Milad_Mafi when I try to run the simulation it says that it will exceed the maximum quota of core hours I have, so I can’t run the simulation. Please help.

Greetings, if the mesh creation has finished, but the Meshing Log includes errors like “illegal triangles”, “tesselated surface not closed” and “Mesh quality check failed. The mesh is not ok”, is it ok if I start a simulation or will the results be off? Thanks in advance.

73

Ignore my previous post, the question has been answered above.

I am trying to mesh the model and every time i do, i get error " Meshing Terminated".
And In mesh log, The following is displayed:

[3] → FOAM FATAL IO ERROR:
[3] Illegal level specification for surface solid_0 region body : minLevel:-5 maxLevel:5 levelIncrement:0
[3]
[3] file: IOstream.castellatedMeshControls.refinementSurfaces.solid_0 from line 0 to line 0.

I tried redoing it many number of times and went through the slides again and again and found no mistakes. Please help.

I am not able to see RadiatorZone in simulation setup

@varunsura,

your error is already in line 2 “minLevel:-5 maxLevel:5”. minLevel must be 5! Try again and tell me if that worked for you.

Hi @wzanin,

counter-check your simulation settings with this project: Project F1

If you still have everything correct I will jump in again and help you out.

Cheers,

Jousef

@ishanbangia,

I can see the RadiatorZone.

Is that what you were looking for? If I did not get you do not hesitate to ask me.

Best,

Jousef

79

May you please check it in my project

Project link : https://www.simscale.com/workbench?publiclink=d434e528-c4e2-4eaf-ac60-ea5c5e2ec136

Its not present in Topological Mapping of Material Selection of Simulation Setup

80

That is right @ishanbangia. Take this one: Project . It already has all you need in it.

If you still have any problems make sure you tell me. I will help you out then.

Best,

Jousef

please help me with the stream lines
I am unable to see U point data
