In the element whose name and solid is given, it means that the amount of reinforcement that will meet the reinforcement area calculated due to the design effects or the regulation could not be selected.
Uncheck the DS (reinforcement fixing) in the reinforced concrete dialogs.
You can increase the reinforcement diameters that can be used for the relevant element in the Reinforcement Selection dialog.
By increasing the dimensions of the relevant element, you can reduce the amount of reinforcement needed.
In the element reinforced concrete dialog, you can give the required reinforcement amount yourself by looking at which type of reinforcement the missing reinforcement has been created.
