MotionView provides a solver-neutral pre- and post- processing environment to facilitate working with other MBD solvers.
MotionView has the following solver interfaces:
MDL models can be exported to any of these solvers for analysis:
| • | User can change the solver mode and then export the model to the particular solver. |
| • | User can register a script to run a solver from within MotionView. Refer to the Tip and Trick, "Start an ADAMS run from within MotionView" available on Altair’s website. |
| • | If the user needs to add any statement specific to the solver, Templex template can be used in the model. Refer to tutorial MV-4010 for some more details about the Templex template. |
| • | The results from these solvers can be post processed in MotionView. |
Copy the folder named solver_neutral, located in the mbd_modeling\externalcodes folder, to your <working directory>.
Exercise
Step 1: Loading a Solver-Neutral Model and Running Different Solvers.
| 1. | Start a new MotionView session. |
| 2. | Copy the folder named solver_neutral, located in the mbd_modeling\externalcodes folder, to your <working directory>. |
| 3. | Load the file model.mdl. |
| 4. | From the SolverMode menu, confirm that MotionSolve is selected. |
| 5. | Click the RUN icon,  , on the Model-Main toolbar. |
| 6. | From the Main tab, specify your output filename as <working directory>\ms.xml. |
| 7. | Select the Simulation type: Transient. |
MotionSolve is launched and completes the run.
| 9. | From the SolverMode menu, select ADAMS. |
| 10. | From the Project Browser, under the Data Sets folder select Solution Options. |
| 11. | Review the Solution Options dataset. |
| 12. | You can enter the simulation parameters for the ADAMS solver into this table. |
| 13. | Click the RUN icon, , on the toolbar. |
| 14. | Specify the output filename as <working directory>\adams.adm. |

Do not complete the following steps without connecting the ADAMS solver to the RUN button.
For this tutorial, you can assume the ADAMS run is complete and go to
Step 2: Comparing Solver Animations.
|
| 15. | From the Script combo box, select the script ADAMS Executable. |
| 16. | Click the RUN button to start the simulation. |
The ADAMS solver is launched and completes the run.
Step 2: Comparing Solver Animations.
| 1. | Click the Add Page icon,  , on the Page Controls toolbar to add a new page to your session. |
| 2. | Select HyperView  from the Select Application drop-down menu. |
| 3. | Click the Page Layout,  , icon on the toolbar and select the three horizontal windows layout,  . |
| 4. | Load the following model and results files into the three windows: |
|
Window 1
|
Window 2
|
Model
|
ms.h3d
|
adams.gra
|
Results
|
ms.h3d
|
adams.gra
|
| 5. | Click the Start/Pause Animation icon,  , on the Animation toolbar to animate the model. |
Notice that if the same solver parameters are chosen, the results from different solvers are in-sync.
| 6. | Click the Start/Pause Animation icon again,  , to stop/pause the animation. |
