Dimension limits in design modeler
 

Hello, I have a question about dimension limits in ansys fluent.
It seems like when one dimension is over 500 metres, the profile will exceed the max bounding size. Here I only set a rectangular and want to extrude it. Its length is over 500m and there is an error when extruding it. How do I break this limit?[IMG]

I understand the problem and to be useful for everyone, I answer this question here.

before begin drawing the geometry, you should go to tool - options and in the unit section, enable the large model support. be careful: you cant enable this option in the middle of the geometry drawing.


Hope this is useful
