Downstream is modeled 2D with 100ft grids (grids around break lines are smaller). The dam (weir) and breach is modeled with the SA/2D Area Connector. I'm using a 0.5 second time step with the full momentum equation. <br /><br />In the simulation I received the following message about 2 minutes after the end of the breach formation time:<br /><br />In green text it read...<br />1D/2D Flow Area -31 Laf Dam<br /><br />The error lasted for about 23 minutes in the simulation (with the number becoming less negative with each time step); the simulation did not crash and has kept running (not finished running yet).<br /><br />Do you have any thoughts as to what caused this message?<br /><br />Thank you.<br /><br />Eric Eric Tothhttps://www.blogger.com/profile/03110833941035943186noreply@blogger.com
