	'''Description:''' The advection_state nodal attribute is used to provide fine grained control over the NOLICA and NOLICAT parameters, so that they can be set on an element-by-element basis. The bathymetric depth at the three nodes of an element are compared to the corresponding nodal attribute values, and if the bathymetric depth at all three nodes is greater than or equal to the corresponding nodal attribute value, the values of NOLICA and NOLICAT will be set to the value indicated in the Model Parameter and Periodic Boundary Condition (fort.15) file. If the bathymetric depth at any of the three nodes of a particular element is less than the corresponding nodal attribute value, the values of NOLICA and NOLICAT will be set to zero on that element.<br />		'''Description:''' The advection_state nodal attribute is used to provide fine grained control over the NOLICA and NOLICAT parameters, so that they can be set on an element-by-element basis.

If the bathymetric depth at any of the three nodes of a particular element is less than the corresponding nodal attribute value, the values of NOLICA and NOLICAT will be set to zero on that element.

			The most common application of this is to set advection_state to a very large positive value (greater than any depth in the mesh) at selected nodes in the fort.13 file at which you want advection to be off. Then, to turn on advection at all other nodes, set the default value in the fort.13 file to a very large negative value, and set NOLICA=1 and NOLICAT=1 in the fort.15 file. <br />
