So I’ve built the storage area connected to the 2D flow area via a SA/2D Connection (wall with culvert). But for some reason, now the water is ignorig the wall completely. The following error popped up during the simulation:
Overall Volume Accounting Error in 1000 m^3: 3.141
Overall Volume Accounting Error as percentage: 11.48
Please review “Computational Log File” output for volume accounting details
