This tutorial was created using ANSYS 7.0 The purpose of this tutorial is to outline the steps required to view cross sectional results (Deformation, Stress, etc.) of the following example.
For this problem we will use the SOLID45 (3D Structural Solid) element. This element has 8 nodes each with 3 degrees of freedom (translation along the X, Y and Z directions).
In the window that appears, enter the following geometric properties for steel:
For this example we will use an element size of 20mm.
Now since the purpose of this tutorial is to observe results within different cross-sections of the colume, we will first outline the steps required to view a slice.
|SECT or (1)||Section display. Only the selected section is shown without any remaining faces or edges shown|
|CAP or (5)||Capped hidden diplay. This is as though you have cut off a portion of the model and the remaining model can be seen|
|ZQSL or (8)||QSLICE Z-buffered display. This is the same as SECT but the outline of the entire model is shown.|
Before we begin selecting cross sections, let's view deflection of the entire model.
From this one may wish to view several cross sections through the YZ plane.
To illustrate how to take a cross section, let's take one halfway through the beam in the YZ plane
Fill in the window that appears as shown below to select /TYPE=ZQSL and /CPLANE=Working Plane
As desired, you should now have the following:
This can be repeated for any slice, however, note that the command lines required to do the same are as follows:
WPOFFS,Width/2,0,0 ! Offset the working plane for cross-section view WPROTA,0,0,90 ! Rotate the working plane /CPLANE,1 ! Cutting plane defined to use the WP /TYPE,1,8 PLNSOL,U,SUM,0,1
Also note that to realign the working plane with the active coordinate system, simply use: WPCSYS,-1,0
Again, let's view stresses within the entire model.
First we need to realign the working plane with the active coordinate system. Select: Utility Menu > WorkPlane > Align WP with > Active Coord Sys (NOTE: To check the position of the WP, select Utility Menu > WorkPlane > Show WP Status)
Next we need to change /TYPE to the default setting(no hidden or section operations). Select: Utility Menu > PlotCtrls > Style > Hidden Line Options... And change the 'Type of Plot' to 'Non-hidden'
Let's say that we want to take a closer look at the base of the beam through the XY plane. Because it is much easier, we are going to use command line:
WPOFFS,0,0,1/16*Length ! Offset the working plane /CPLANE,1 ! Cutting plane defined to use the WP /TYPE,1,5 ! Use the capped hidden display PLNSOL,S,EQV,0,1
Note that we did not need to rotate the WP because we want to look at the XY plane which is the default). Also note that we are using the capped hidden display this time.
You should now see the following:
Now, for something a little more impressive, let's show an animation of the Von Mises stress through the beam. Unfortunately, the ANSYS commands are not as user friendly as they could be... but please bear with me.
You should now see an animated version of the contour slices through the beam. For more information on how to modify the animation, type help ancut into the command line.
