I can use DM draw my model, and define the dimension what I want. Besides giving a value I can set the dimension to the parameter and give a name to this parameter. After this step, I can change its value in the workbench.   My question is how to use an equation in the workbench for change the parameters? For example, I want to make the ratio between total value and wet area equal to a constant. when I change height all dimensions will change and the result can be calculated by workbench itself and use in DM.

Here is a DM model with a sketch and two dimensions, L1 and L2.

I clicked the box next to their names that adds a D and puts them in the Parameter Editor.

Then, in the Parameter Editor, I gave L1 the name height, while I typed an expression for L2 that was 3*@height.

I think that is similar to what you are trying to accomplish.

The expressions in DM are limited to this short list, which you can find in the Online Help.

Yes, you are right, I think I should check the manual before asking others. Thanks!
