This tab (Figure 1) contains methods to assist the user to assign the initial conditions for the temperature parameters as described in the Temperature IC sections. In addition to opening the Temperature Parameters form, the Initial Conditions settings are accessible via RMC on the Temperature module (Figure 2).

This tab contains 2 main sections: Initial Conditions for Water Temperature, as shown in Figure 3.

Initial Conditions for Water Temperature: The water temperature initial conditions can be set to a constant value or assigned to vary spatially. To set either of these options select the Assign button. To set a constant value simply enter a value in the Constant field under the Values to Set frame. The user can set this constant to certain layers in the Layer Options frame. If the user wants to use spatially varying initial temperature determined by a polygon, they should check the box and press The Apply Cell Properties via Polygons form as shown in Figure 4. If the values to be set vary spatially based on XYZ or from vertical profile data, they should select one of these two options in the Values to Set frame. The user should then browse with the Add file button in the Data files frame to add these data sets. Various interpolation options are provided in the Interpolation Options frame, including replacement of existing data, and using the maximum or minimum values. Selecting the More… button provides further interpolation options including order of inverse distance weighting (IDW) interpolation, number of neighboring points, and number of quadrants.

Initial Conditions for Bed Temperature: It is able to set constant bed temperature by setting a value in the Uniform Bed Temperature box or check Use Spatially Variable Bed Temp and Thickness checkbox to assign a spatially varying initial temperature, by layer (Figure 5). The options and format of data files to upload to are described in Apply Cell Properties via Polygon. It also can select to apply cell properties for a specific layer or all layers in the model.
