Before you start ANSYS, you should have these CAD models ready
1. Steel chassis and composite catamaran Assembly
2. Impact objects (Optional)
Open up ANSYS
Drag an ACP (Pre) Analysis System onto your workbench
Import the chassis and catamaran assembly into your geometry then edit the geometry using Spaceclaim → TUTORIAL: ANSYS - Beam and Shell Elements (Uni-body chassis)
Once you have prepared your model in Spaceclaim, prepare you model in ACP (Pre) Setup → TUTORIAL: ANSYS - ACP (Pre)
After your ACP (Pre) block is finished (update all modules so that they have a green check mark), add a static structural analysis system and connect Setup from ACP (Pre) to the Model of Static Structural
Then connect an ACP (Post) to the workbench → TUTORIAL: ANSYS - ACP (Post)
In Mechanical of Static Structural, add point masses to the model → TUTORIAL: **in development**
Select a node on that chassis that is in contact with the impact object and create a named selection for it
Add Nodal Displacement and Nodal Rotation, then lock the node selection in place
Add a fixed support to the back face of your impact object
Add acceleration to your model, in the direction away from the impact object. For every G of force you want to simulate, add 9.8m/s^2 to acceleration (i.e. for 5Gs, acceleration should be 49m/s^2).
Add Deformation and Stress to the Solution
*IMPORTANT* Click on Tools>Variable Manager and add a variable named "contactAllowEmpty", set the value to 1 and check off the checkbox
Run your simulation
Repeat steps 6 to 15 for every test case you need
1. Your workbench should look something like this
