Trouble getting internal storage area connector to work in 2D

[Lonnie A]

I’m trying to add a storage area connector internal to the 2d storage area. I feel I’m doing everything correctly but I can’t get the model to run with it in there. Runs fine without it but when I enter the connector and try to run it’ll spit out the following error. (just the header pasted below as there is about a dozen more lines)
forrtl: severe (157): Program Exception – access violation

This is what I have entered into the mesh.

I’ve made sure the weir is higher than the cell face and the culvert is higher than the lowest elevation in the two connecting cells. One thing I can’t figure out is the storage area connector weir is going down to elevation 100 when coded in but the lowest cell elevation is 972?

If anyone has an idea on what may be the issue I’d appreciate it. The sample single 2D with connector data set model runs fine so I don’t think it’s a hardware issue.

Have you tried having more than one element on each side of the connector, try refining it to have more than one and see if that helps. If you are willing to share the files, I can take a look and see if I can find anything.

I never could get it to work in that model. Same exact approach though worked fine in another model so not sure what the deal was with it. I didn’t save it and ended up editing the surface or I’d share it. One thing I found though is that upstream/downstream matters in the current version. I had drawn upstream downstream based on the channel, but the channel in the 2d had no flow assigned and was being backwater fed from the 1D model. So tailwater would continue to rise and no flow would pass through culvert until upstream cell got wet. Once it got wet it would function. If reversed upstream and downstream it would function. Spoke with Gary B at HEC and he said they have it fixed now so it’ll work correctly in the official release version.
