    Thank you Toby.
    I have a question. What do the Faces FacePoint Indexes and Cells Cell Point Indexes represent? If I could connect cell face points then that will be great.

    Thanks

    I was thinking the same but number of face point co-ordinates are almost less than half of shear stress. The number of values for shear stress is 626514 and number of face point co-ordinates is 226928.

    Whole model is more than 2GB. I reduced the size of project area for same terrain. For the small area, it worked well. Looks like I should decrease the size of project area.
    Thank you again.

    I transferred the file.

    Thank you Lee. .tif file is not even 1GB. Its only 20 MB. I will try with other options if it works.

    Thank you.

    Thank you Toby. There is FacePoints Coordinate in HDF but its matrix does not match with shear stress matrix.
    Wet cells are around 400000.
    The specification of my computer is:
    i7 -6500U [email protected], 8 GB RAM and 64-bit operating system.

    Thank you everyone.

    I am working on canyon.

    Yes, adding the layer.

    The resolution of terrain is 1 feet x 1 feet. I tried creating smaller number of mesh elements. I did not face that problem. I am guessing, its due to resolution. Because of that I am wondering if I could extract from HDF.

    I tried to open with both .tif and .vrt in Arcmap. When I upload the .vrt or .tif file, Arcmap will just crashed.

    I saved the result as raster but I could not open that in ArcGIS.

    Yes, there is nothing to do in HDF for velocity x and y.
    But shear stress is calculated on the face of cell. Because of this, there is not co-ordinate for shear stress value. I have to plot shear stress in a scatter plot. For that I need (x,y,z) points. z as a shear stress and x and y as a co-ordinate.

    It did not crash. It showed the error and model was stopped.

    For the smaller time step (less than 1 sec), results look reasonable. I tried using full momentum equation but I got an error saying “Error with program: RasUnsteady64.exe Exit Code = -1073741819”. Then, I ran the model both by increasing and decreasing the size of mesh. I got the same error. Could you please tell me what might be the reason behind this error?

    Thank you

    Thank you Cameron for the reply. I will check courant criteria as well as try once with full momentum equation.
    Since, I am modeling for small canyon I used smaller grid cell size (4 feet). And the resolution of terrain is 1 feet. Does it have any relation with simulation?
