Any idea why I would be getting these errors when trying to add a C3D Geotiff?

6.0 and higher doesn’t like C3D’s GEOTIFF offering. 

One workaround is to bring it in using 5.07 then move on to 6.2. 

Dotsoft can create compatible tif and flt files..

That worked! Thanks!

That would never had occurred to me, so easy once you know the solution.

Any chance you could point me in the correct direction on why I can't see the RAS Mapper added Boundary in the Unsteady Flow viewer?

 

I need it to show up to then add precipitation values to run rain on grid...

 

This is a C3D forum, I'm still looking for a HEC RAS 2D forum on the web, nothing yet..

Rain on grid is distributed evenly over the 2D flow area ..you probably haven’t defined a 2D flow area yet

Just looked at your screenshot.. so you do have a 2D flow area for that geometry 

 

You need to associate your Unsteady Flow with a Geometry... Right click on Geometry in RAS Mapper and Manage Geometry Associations…..
