For those who run into the same issue – I resolved this by defining the three arguments needed in Compute_CurrentPlan(). The third argument is Blocking Mode and when set to True, the code waits for the RAS computation to complete before moving to the next line of code.

So use:
hec.Compute_CurrentPlan(None, None, True)

I checked what was being seen by assigning a variable and then printing.
test = hec.Compute_CurrentPlan(None, None, True)
Print(test)

Thomas, I have been using reference points (added in the geometry editor before runnning), then nagivating to them in the hdf file using python to plot them. You could also navigate to a node or cell face of interest in the hdf file, alternatively.

I realized this only happened for a certain geometry file within my model and a very wise coworker just helped me resolve the issue – if you select the box for Geometry Preprocessor in the Unsteady Flow Analysis window, it runs! I hope this helps others with the same problem.

Hi there – I am getting a similar error that causes my model to crash. Error is below. I am trying to run a model that runs fine in 5.0.6, but gives these errors and crashes when I try to run it in 6.1. Any ideas on how to fix this?

I asked the same question on this post and Chris replied that unfortunately he doesn’t think there is a way to get output specifically on a profile line from the HDF file. https://therassolution.kleinschmidtgroup.com/ras-post/controlling-hec-ras/#comment-8650

I am using Version 6.1 and trying to do the same – I do not see where values at profile lines are stored within the HDF file and I wonder if there is an output option to write the values at profiles lines to the hdf file to then be able to extract them. I have not found the solution yet, has anyone made progress on this issue?
