Resume the ANSYS Tutorial and make modifications to it as discussed below. To resume the ANSYS tutorial:

Start ANSYS; Specify the same directory but use a different jobname. Once ANSYS comes up, in the Utility Menu, click on:

Utility Menu > File > Resume from

Specification
1. Start-up and preliminary set-up
2. Specify element type and constants
3. Specify material properties
4. Specify geometry
5. Mesh geometry
6. Specify boundary conditions
7. Solve!
8. Postprocess the results
9. Validate the results

Problem Set 1

...

Consider the case where the displacement constrains constraints at A and C are interchanged i.e.

...

Re-solve the truss problem with the modified constraints. You . Fom your ANSYS solution:
1. List the reactions. Note that you can save the reaction listing as follows: in the window that comes up with the listing of the reaction forces, click on:

File > Save As

2. Determine the force in each truss member and whether the member is in tension or compression.

Tips: Start from your ANSYS solution to the truss tutorial problem but use a different job name as follows:

  • Start the ANSYS Product Launcher. Specify the same directory as for the tutorial but use a different jobname. Once ANSYS comes up, select: Utility Menu > File > Resume from. Choose truss.db and click OK.

Note that you can delete constraints using:

Main Menu > Preprocessor > Loads > Define Loads > Delete

It works similar to how you apply loads.

Tip: You can plot the displacement constraints in the Graphics window as follows:

Utility Menu > Pltctrls > Symbols

Select All Applied BCs for Boundary condition symbol. Click OK.

You might have to use :

Utility Menu > Plot > Replot

or

Utility Menu > Plot > Multi-plots

for the constraint symbols to appear in your plot.

Determine the following results from your ANSYS solution:

1. List the reactions. Note that you can save the reaction listing as follows: in the window that comes up with the listing of the reaction forces, click on:

File > Save As

2. List the element forces. From this determine the force in each member and whether the member is in tension or compression.
