basically parametric solution is quite complicated for my design, because, when I want to change the length of the legs, it will affect whole parts. In order to handle this problem, I have to parametrize every parts.
sometimes I get another error:
[error] Adaptive solution setup, process abc3d: The ABC boundary 'Rad1' is entirely within the model. Non-physical solutions could result.
Rad1 is my radiation boundary, so, it must contain my model. why does it give this warning?
