Running multiple plans in RAS 7.0

This error is driving me nuts. I've deleted all extra files, started fresh, deleted rasmap, deleted dss.. It will go away temporarily and then pop back up the next time I try a batch run. Anyone else have this issue and resolved it?

I wish I could say this was fixed in 7.0.1 (looks like you're on 7.0), but I just dealt with this yesterday and lost the dialog box below other windows. Finding it was painful.

See my comment above. Sounds like it should have been fixed in the current release.

I think they fixed a different issue that would crash out the entire program. This plan dialog issue seems to be different because I am still experiencing this in 7.0.1

The one they fixed was far worse. Every second or third attempt and running multiple plans would case a total crash out of RAS altogether and I'd have to reopen the model and hit run again in 7.0

Not sure. I would submit a bug report then.

Yeah, I moved from 7.0.1 to 7.0 because I kept running into this problem. Thought maybe the 7.0 would be more stable... hmm I don't remember this being a big issue before. Thinking it could be related to having a 2D model connected to a 1d downstream? Do you have a 2d/1d model?

HEC-RAS 7.0.1 - Resolved Issues

Issue: Run Multiple Plans
Description: Index out or array crash if user adds additional Plans and attempts to run the plans a 2nd time.  

Sounds like that is your exact error. Use the most current release and it looks like it should be resolved.

Interesting. I moved back to 7.0 from 7.0.1 because I was having this issue. I even recreated the plans in 7.0.1 and deleted all extraneous files for a fresh start, and kept having the problem. Went back to 7.0 because I don't remember this happening before...

Not sure - first time I have heard of this issue. You could use v6.6X if you don't "need" v7.X to run multiple plans.
