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
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.
