    If you're importing cross sections into ICM, EACH VERTEX of your cross section (each chainage elevation) needs an XY. ISIS (unless its fully georeferenced) only has XY for the centroid of the cross...

    2D Gullies

    An issue we frequently seem to come across is 2D gullies causing instability issues in ICM. Has anyone else had experience of this or has anyone found any solutions to improve their stability?

    2D Exporting Speed

    Hi All,

    Sorry if this is a repeated post.
    Has anyone found an approach which gives them the quickest export time for 2D results. I find that exporting to MIF and only exporting depths greater...

    Hi Jimmy67,

    (assuming you have no user-defined controls or pumps nearby, and your recorded data is accurate)
    From your velocity plot, it looks like you're overpredicting a baseflow or perhaps a...

    Hi Joe,

    Just thinking off the top of my head - if you link a your foul-subcatchment-draining-manhole to a flap valve to a 2D outfall at ground level (and seal the manhole), this may only allow...

    ICM - Base Linear Structures

    Using base linear structures in an ICM model seem to increase validation times massively. Also just accessing the information behind the objects or editing them at all seems to take a long time to...

    Hi Duncan,

    I have had a look at the conduit geometry but can't find anything out of the ordinary. I'll send over a transportable - I will probably have to use Thru Drop Box due to the size of the...

    ICM validation time

    Hi all,

    I have built a linked 1D-2D model with about 2M Triangles and 10k nodes. Validation times for this are very long, over half an hour - 45 mins. Is this usual for a model of this size? or is...

    Hi Bob,

    Thanks for the reply.
    I have reduce the timestep down to 10, 5 and 1, with 1D-2D minor time step linking, and I am still getting this same error. Are there any other fixes I could try or...
