Python Script for Multi-Step Analysis: Activating/Deactivating Loads Per Step

Francesca

Hello everyone,

I am trying to automate a multi-step analysis in the Static Structural module using Python scripting from the Automation tab.

My goal is to configure the loads and supports as follows:
Gravity: This must be active in all analysis steps.
Displacements: I have multiple displacement boundary conditions. For each step, only the displacement with the corresponding step number should be active. For example:

• In Step 1, only 'Displacement 1' should be active, and all others deactivated.
• In Step 2, only 'Displacement 2' should be active, and all others deactivated.
  ...and so on.

Could you provide some guidance or a sample script on how to programmatically control the activation and deactivation of boundary conditions on a per-step basis?

Thanks in advance for your help.

What you are looking for is the API method on the displacement object itself. Below will set a disp. object as active for step 1 and deactivate for 2 and 3. Code the steps to your needs in your analysis.

Disp1.SetActivateAtLoadStep(1, True)
Disp1.SetActivateAtLoadStep(2, False)
Disp1.SetActivateAtLoadStep(3, False)
