Clearance Compute

Tools Clearance Compute
When you request to run a Clearance study, Adams PostProcessor calculates the minimum and maximum distances between a pair of objects using data from a selected Simulation. It adds the information to the animation associated with the simulation, which you can subsequently run. You can also generate a report of the data and plot it.
 
Note:  
The number of frames in your animation can have a significant effect on the accuracy of the distances reported. Therefore, for best results, we recommend that you perform at least one clearance study with a large number of frames in the animation (time steps in the simulation).
 
Caution:  
Clearance Studies are not designed to handle cases where one geometry (I or J) is completely enclosed by the other. Unexpected results can occur.
 
For the option:
Do the following:
Simulation
Select the simulation data against which you want to run the clearance study.
Treat Flexible Bodies as Rigid
Select if you want to calculate the clearance study as if flexible bodies were rigid. This reduces computations and allows the clearance study to run faster but does not give you information about the effects of flexibility.
