SMS:ADH Hot Start File

From XMS Wiki
Jump to: navigation, search

The hot start file is mandatory and contains initial conditions for each node of a mesh. ADH allows for the specification of depth and velocity hydrodynamics, and sediment concentration and displacement datasets. The model requires at least depth initial conditions for hydrodynamics, and non-specified conditions will be defaulted to values of zeros (0.0).

ADH Hot Start (*.hot) File

The *.hot file format is actually the same as the ASCII dataset Files (*.dat) but necessitates the special extension since it should only contain following specifically named datasets:

Hot Start Datasets
Name Initial Condition
"ioh" or "IOH" Depth
"iov" or "IOV" Velocity
"ioc" or "IOC" Sediment concentration (SMS currently does not support this)
"iod" or "IOD" Sediment displacement (SMS currently does not support this)
Name Initial Condition
"ioh" or "IOH" Depth
"iov" or "IOV" Velocity


SMS will recognize and read in a hot start file if the dataset definition matches the current mesh definition (number of nodes and elements) and the ADH is the active model (other models also use a *.hot extension). Valid datasets with the above names are added to a locked "Generic Folder Locked.svg ADH Hot Start" folder in the Project Explorer. The folder and datasets can not be deleted or renamed from the tree. See Hot Start Initial Conditions for interface information.
