[Workbench] Ansys workbench meshing error

mechrules14 · September 8, 2015, 07:23

Hi,
I am using ansys workbench. I have a simple rectangular 2D surface with length 100mm and breadth 50mm. i meshed my geometry with mesh size 0.001mm. But the process aborted showing an error message "Invalid geo entity error while meshing, process aborted"

I have also used Inflation in my geometry. Please help me why such an error. is there any other Options to use such a small mesh size.

Maybe you could post some pictures/screenshots of your geometry and write kind of settings you used? What are your parameters for inflation? etc

Hi Maxim,
I dont know how to attach a Picture here. if u can send me your mail address, i will send the screenshot.

Anyways i just write some Details about my mesh:

Sizing:

Advanced Option: on
relevant centre: coarse
intital size seed: active assembly
smoothening: medium
min size: 0.001mm
max face size: 0.001mm
growth rate: Default
min edge length: 25mm

Inflation:

use automatic Inflation: None
Inflation Option: smooth transition
Transition Ratio: 0.272
max layers: 2
growth rate: 1.2
Inflation algorithm: pre
view advanced Options: no

With These Option it almost took 4 days, still my mesh is not ready. please help me
regards
