About the keyopt command in ansys. 20

1. First, follow the steps shown in the diagram to establish a key point.

2. Then select Copy---KeyPoints, then select Key Point 1, and click OK.

3. Set the X direction to move 10 and copy a new key. Then select the "fit view" button in the third image and you'll see the two key points in the fourth image.

4. Then follow the steps below to create a polygon.

5. Finally, move 20 in the x direction to create another identical surface.

6. Use the Stretch command to stretch a body along the outer normal, as shown in the following figure, and you're done.

It is not easy to grasp KeyOpt well, which means that you already have a deep understanding of this unit. For a beginner, keyopt can be used by default. However, be careful to see what each keyopt item means, and whether the keyopt option is the same as you understand it.

In this way, slowly, you will know how to set up keyopt.

I recommend Wang Xinmin's "Ansys Engineering Structure Numerical Calculation", each of the above commands has an introduction, which is very good.

keyopt,3,1,0

1 is the number of the keyopt to be defined(keyopt(knum) defines the keyopt number.

0 is the value of this keyopt.

1,0 represents linear solution(default)keyopt,3,2,2

2,2 represents the 1-D longitudinal spring-damper(uy degree of freedom).

Different instances? That's not too much.,The keyopt settings of each unit are different、、、 it must be based on different units.,It's really hard for you to ask like this.、、

Ay! There are really too many questions, you still have to be specific to which unit you want to use! Or not

Stand still o (> o don't.
