ICM Live - cascading simulations

Efficient hydraulic modelling implies some compromises between : The size of the modelled region The spatial resolution and accuracy of the results The "cost" of these simulations, in terms of computer time and power In order to maintain a balance between these elements, it can be of interest to setup models working at different scales, that can interact. Cascading models : The example below exploits 2 different models : → a hydrological model : Setup at a large scale, it allows...

ICM - correct mesh errors

This post is part of a series of articles about modeling coupled 1D / 2D river and urban water and models optimizations 2D modeling are consuming resources and computing time, it is therefore essential to work with own grids, and optimize them. This requires the following checks: avoid computational elements uselessely too small, ie which do not provide relevant information for the purpose of the study. This point is important, it is in fact the size of the smallest element of calculation...
