how to see the vibration mode

I have finished my analysis, with eigen and static.
In the eigen analysis, I also add customcommand and select modesofVibration.
So, how to show the vibration modes of the model in the postprocess?

Dear Yulu Liu,
you should choose modes of vibration both in the result and in the deformation drop down menu.

If you also want to output eigen values look at this link

What do the options mean as shown in the picture attached?
When I set the grid size 10, and if I want 10 meters long beam, I need to input 100. (Why is it?)
So if I use these units mass(kg), and time(s), what is the unit of force?

Those options in the grid editor are just parameters to set up the grid.
The grid a pure graphic item and has nothing to do with the unit system.
When you set the grid size = 10 (units) you are just telling STKO that the grid step for the grid-snap is 10 units.
But remember that in STKO we don't have a unit system, so it's up to you to tell what 10 units mean.
For example if you are modeling in millimeters, then with a grid size = 10 (units = millimeters) you will have a grid-snap every 10 millimters, and to draw a 10 meters long beam, you need to cover 100 grid samples.
But as I told you this has nothing to do with unit system
