Rule of thumb for sub modelling cut boundary
Rule of thumb for sub modelling cut boundary
(OP)
Dear Experts,
Is there a rule of thumb regarding the distance of the cut boundary relative to the point of interest. I find I have to try different distances /re analyse to verify that the cut boundaries of the submodel are far enough away from the concentration
Thanks
Eddie

I will be interested what boundary condition you apply on the cut line/surface? Fixed, Free, Spring ? What spring constant?

I would work from a free body diagram and apply forces (and moments if necessary) as a (variable) pressure over the cut surface. The distributed loading on the cut surface would be in balance with all other loading on the model.

I was referring to an FEA model regarding the sub model.
Thanks for the rule of thumb anyhow.
