I try to run a simulation through Asnys Fluent and it gives error at Set-up step. Here is the procedure I have taken:
Analysis Systems --- Fluid Flow --- FluentMarch 7, 2022 at 9:13 pmMarch 7, 2022 at 10:33 pmhamiddehkordiSubscriberHi
thanks for the respond, yes I have done that, I explained in the post my procedure.
i am not sure if this is relevant but in order to run ansys on my computer, i need to connect remotely to the college server to get the license.
March 8, 2022 at 1:26 pmKarthik RAdministratorHello:
Are you able to open Meshing? Do you see any error when you open the mesh?
March 8, 2022 at 1:41 pmhamiddehkordiSubscriberHi
no error in the meshing process
March 8, 2022 at 5:24 pmKarthik RAdministratorAnother quick question - do you see this issue when you attempt to launch Fluent on any generic model? A quick test would be to open a fresh WB instance and set up a simple pipe flow simulation from scratch. Are you able to launch Fluent when you do this?
March 9, 2022 at 1:53 amhamiddehkordiSubscriberHi
I am going to set up a simulation using DM. Meanwhile could you tell me, Fluid Flow (CFX) should exist in "Analysis Systems"?
March 9, 2022 at 3:09 amhamiddehkordiSubscriberHi
I made an example: Flat Plate Boundary Layer
Below is the DM drawing:
when I click on set-up, same message came up!!!
March 9, 2022 at 1:41 pmKarthik RAdministratorHello:
Instead of attaching your screenshots, please paste them directly into your post. Ansys employees are unable to download attachments on this Forum.
Regarding your other question - Yes, you should see CFX under analysis systems. You should also see it under Components on WB.
March 9, 2022 at 3:38 pmMarch 9, 2022 at 3:38 pmMarch 9, 2022 at 4:02 pmRobAnsys EmployeeCan you launch Fluent from the Start menu? If there isn't an icon please refer to the "standalone" thread at the top of the page.
March 9, 2022 at 4:20 pmhamiddehkordiSubscriberYes I have done that before and i did not work Rob. There is something interesting in the standalone pass, you mentioned in another discussion the path below:
C:\Program Files\ANSYS Inc\v212\fluent\ntbin\win64\fluent.exe" -r21.2.0 -shortcut
Our technician also give me the same instructions to do , in the path there is a folder V212
but what I have is V221
March 9, 2022 at 4:59 pmRobAnsys EmployeeYou may need to change the path - 2021R2 is V212, 2022R1 is V221.
March 9, 2022 at 9:47 pmMarch 10, 2022 at 2:35 pmRobAnsys EmployeeYou've meshed the metal bit. That's fine for Mechanical, but we're interested in where the fluid goes in CFD.
March 10, 2022 at 2:38 pmhamiddehkordiSubscriberthanks Rob, this comes back to my original question, I do not know how to mesh the fluid instead of solidMarch 10, 2022 at 2:47 pmRobAnsys EmployeeYou need to use volume extraction or the like in CAD or SpaceClaim. Basically, we want the geometry volume to be the volume inside the casing. Make sure you assign labels (named selections) to the inlet and outlet faces.
March 11, 2022 at 1:25 pmKarthik RAdministratorYou need to extract the Fluid region corresponding to the solid geometry. Have you done this already? If so, can you see this region in Ansys Meshing?
March 11, 2022 at 3:20 pmhamiddehkordiSubscriberHi
no, is there a link or video that I can watch
March 11, 2022 at 4:37 pmRobAnsys EmployeeThere are probably some tips in the Help parts of SpaceClaim. Where did the geometry come from?
March 11, 2022 at 5:28 pmhamiddehkordiSubscriberSolidworks as a step file
March 14, 2022 at 2:05 pmRobAnsys EmployeeIf you know how to use Solidworks do the volume extraction there: we want the fluid region. In CFD we only model the solids if we need to include the heat transfer effects.
March 14, 2022 at 6:08 pmhamiddehkordiSubscriberThanks, Rob I watched a video exactly mentioned what just you said
March 16, 2022 at 11:44 amhamiddehkordiSubscriberthank you so much, it helped
