How to do 1/2 or 1/4 model simulation? How to insert plane to cut?

Hi, all;

This might be simple questions...as I am beginner....

Would you advise and comment how I can do 1/2 or 1/4 model simulation?

Do I need to generate 1/2 or 1/4 model at the beginning? Or if I can cut or put the symmetric plan if I have already whole model?

Is it done by putting symmetric plane in step of giving constraint?....it seems asking where is the symmetric plane...how I can generate the symmetric plane in the model if I need? I could insert split line for mesh control...is it similar way?

Below is the simplified model with two thin parts assembled....how I can have the symetric plane to perform1/2 or 1/4 model simulation? how I can put or insert symmetric planes which I think that it needs to panetrate below model to cut 1/2 or 1/4 through two parts assembled?

Or, is there any site or docs...I can learn this basic?

Any input will be appreicated.

Thanks,

Cheol
