Boundary Condition Error
I seem to be having an error whilst trying to run my model, with a message appearing saying that the 'Boundary Condition has not been defined'. However, fixed supports have been defined at the base of the abutments and integrated into the construction stages.
If you could have a look at the attached model it would be greatly appreciated.
Actually the issue was due to the definition of boundary change assignment. Kindly refer the image below.
Besides this, I'd also like to suggest that first stage needs to be modified. It was noted that elements were activated with 0 age in first stage and the loads were also activated on the first day. This would cause huge deformations as the concrete age is 0 when loads start acting. To go around this, I'd recommend giving the age as say 29 days and the duration of the stage as 1 day, as shown in the image below.
