Specifying Multiple Load Cases in Autodesk Simulation Mechanical

In Autodesk Simulation Mechanical, you can specify different or multiple load cases for the applied load. This will help you to get the results for multiple load combinations in a single run of analysis. For example, if you want the results for different force magnitudes on a same model than instead of running the analysis separately for all the magnitudes, you can specify multiple load cases in a model that will define the different magnitudes of the force. After defining different load cases, when the analysis is performed, a separate set of results will be displayed for each specified load case in the Result environment of Autodesk Simulation.

To specify multiple load cases in Autodesk Simulation, choose the Parameters tool from the Model Setup panel of the Setup tab in the Ribbon; the Analysis Parameters dialog box will be displayed, refer to Figure A. In the Analysis Parameters dialog box, by default, the Multipliers tab will be chosen. In this tab, the Load Case Multipliers table is used to add multiple load cases for the applied loads. Note that the rows of this table represents load cases. You can add multiple rows, as required, for representing load cases by using the Add Row button. Figure B shows the Analysis Parameters dialog box with multiple load cases added.

Validating the 3D Plant model in AutoCAD Plant 3D

In AutoCAD Plant 3D, you can validate your 3D plant model and correct the errors in it based on the validation report. In addition, you also need to validate the 3D model against the P&ID in order to make sure that the components or parts of the 3D plant model matches as per the components or parts of the P&ID.

Before you start the validation, you need to specify the type of errors  to be included in the validation report. To do so, enter VALIDATECONFIG command at the command prompt in AutoCAD Plant 3D; the P&ID Validation Settings dialog box is displayed, as shown in below figure. In this dialog box, expand the 3D Piping node and specify the error types to be validated in the 3D model. Next, you need to specify the types of mismatches to be checked between the 3D model and the P&ID. To do so, expand the 3D Model to P&ID checks node and select the check boxes of the mismatches to be checked. Next, choose the OK button from the P&ID Validation Settings dialog box.

After specifying the validation settings, expand the Plant 3D Drawings node in the Project Manager. Next, right-click on the drawing file and choose the Validate option from the shortcut menu displayed; the Validation Progress message box will be displayed and the process of validation will be started. Once the process of validation has been done, the Validation Summary window will be displayed. The Validation Summary window all the errors available in the model. Select an error from Validation Summary window; the error type and the action to be taken to resolve the particular type of error selected will be displayed in the Details area of the window.
