Mesh Generation error

[Zulong Liu]

Hi,Everyone.

         I am a green hand by using THERM(VERSION 7.8.80.0),it continuously get an message of mesh error as I had do a lot of effort to modify the model.

       This error comes when I imported a warm edge spacer.This model is running well with normal spacers and the warm edge spacer is running well in other models(mullion,transom).But when I combined them together the problem comes.

       It will be highly appeariciated if  anyone help to check and point out the problem?

Hi Zulong,
As I remember there was a rule of modeling in the Therm that warned the distance between a polygon vertices should be more than 0.1mm.

Try to redesign the steel part of the edge spacer and run again.

Kind regards,

Zugur

Hi Zulong,
Now I have tried to run your file and it's working after a little revision(divided some polygons).
Try to open it and run on your computer.

Additionally, check all the outside boundary conditions set by you, actually for bottom IGU (see the screenshot below)

Kind regards,

Zugur
