Abaqus/CAE evaluates the expression field at different locations on the model depending on the type of region that you selected when you created the interaction or prescribed condition. Table 1 indicates the locations on the model that Abaqus/CAE uses for evaluation of the expression field.
Next, Abaqus/CAE multiplies the magnitude that you specify for the spatially varying parameter, such as a pressure magnitude, by the evaluated expression at each element or node to determine the final values that are submitted to the analysis. The expression field is applied to magnitudes in the interaction or prescribed condition, including the real and imaginary parts of complex magnitudes. Beam and shell gradient values, such as gradients in temperature, are not affected by the expression field. During the analysis, Abaqus applies any amplitude that you have specified for the interaction or prescribed condition. Analytical field and datum coordinate systemIn Abaqus/CAE, when the Analytical field uses the Local coordinate system, the field is evaluated based on the transformations with respect to the Assembly Global-Coordinate system. The Instance assembly transformations are evaluated if the analytical field is created in the load module and Instance level datum Coordinate system (example: Part-1-1.Datum-1) is selected. The Instance assembly transformations are not evaluated if the analytical field is created in the property module and part level datum Coordinate system (example: Datum-1) is selected. |
