14.3 Color Map

The Color Map defines how FEBio Studio will calculate the color that is used to display the model in the Graphics View. The Color Map's properties can be accessed by selecting the item in the Model Viewer entitled Color Map. The properties will then be listed in the Properties Window below. The following properties are defined for the color map.
• Data field - allows the user to select the data field that FEBio Studio will use to define the color of the model. The color of the model is defined by the data field and the color gradient (see below).
• Gradient smoothing - Colors the material by drawing a fringe plot of the selected data field. When gradient smoothing is on, the fringe colors are smoothed to produce a continuous transition between fringes. When this option is off, a discrete set of colors is used instead.
• Color map: defines the color map that will be used to color the model.
• Nodal values - FEBio Studio defines nodal data and element data. When displaying element data, the element data is projected to the nodes to produce a smooth rendering of the data. However, when this option is turned of, element data will be displayed by using a single color for each element. This will produce a discretized drawing of the data, but will be truer to the actual data since the element data is not interpolated before displaying.
• Range type - FEBio Studio keeps track of the range of the selected data field (that is the minimum and maximum values). The user can use this option to select a dynamic range (range is updated for each state independently), a static range (range is calculate over all the states) or user range (user defines the minimum and maximum values).
• Range divisions - changes the number of fringes that will be drawn on the model.
• Show legend - allows you to toggle the displaying of the legend bar in the Graphics View.
• Legen Orientation: sets the orientation of the legend bar (horizontal or vertical)
• User max/ User min - defines the minimum and maximum range value when using the user range option for range type.
When FEBio Studio starts, the colormap is turned off by default. To activate it, select the enable button in the Model Viewer. Similarly, to disable the color mapping, simply press this button again. When the colormap is turned off, FEBio Studio will use the material colors to display the model in the Graphics View.
The color map displays scalar values. For tensor variables, the user can select the sub-components of the tensor as well as some typical scalar quantatities that can be derived from the tensor. The following tables explain these components for the different tensor types.
 Vector field components (vec3f) Description X The X-component of the vector Y The Y-component of the vector Z The Z-component of the vector XY YZ XZ Total (i.e. the vector norm)
Table 14.1 Vector field components
 Symmetric second-order tensor components (mat3fs) Description X The X-component of the tensor Y The Y-component of the tensor Z The Z-component of the tensor XY The XY-component of the tensor YZ The YZ-component of the tensor XZ The XZ-component of the tensor Effective The effective or “von-Mises” value: 1-Principal The first (i.e. largest) eigenvalue 2-Principal The second (i.e. middle) eigenvalue 3-Principal The third (i.e. lowest) eigenvalue 1-Dev Principal The first eigenvalue of the deviatoric tensor. 2-Dev Principal The second eigenvalue of the deviatoric tensor. 3-Dev Principal The third eigenvalue of the deviatoric tensor. Max Shear The “max shear” component:
