Apply Boundary Conditions

Apply boundary conditions that constrain the tank during the pressure loading.

  1. Switch to the Load Module.
  2. Create a boundary condition (BC > Create) to constrain the displacement of the tank base.
  3. Set the step to Initial and select Displacement/Rotation. Click Continue.
  4. Use the viewport to select the six surfaces on the base of the tank and click Done.

  5. Select U1, U2, and U3. Click OK.

Now create an additional displacement constraint to further constrain the model.

  1. Click BC > Create and again set the step to Initial and select Displacement/Rotation. Click Continue.
  2. From the viewport, select the four surfaces shown below and click Done.

  3. Select U1, U2, and U3. Click OK.
