The ABAQUS FAQ


15. ABAQUS/Viewer - Mesh Plots

Q15.1 : How do I plot the mesh?

Click on the Mesh Plot icon, on the LHS.


Q15.2 : How do I generate a wireframe mode of the mesh?

Click on the wireframe icon after clicking on the Mesh Plot icon.


Q15.3 : How do I generate a hidden line plot of the mesh?

Click on the hidden line icon after clicking on the Mesh Plot icon.


Q15.4 : How do I generate a shaded view of the mesh?

Click on the shade icon after clicking on the Mesh Plot icon.
Notice that the icons : wireframe, hidden line, shade icons appear together respectively.



Q15.5 : How do I generate a view of the undeformed mesh with shrunken elements?

Click on the Undeformed Shape Options.... and this will bring up Undeformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Labels tab if it is not already selected.
Click on the following :


Show Element labels 
Show Node labels
 Show Node symbols (if necessary)
values of X, Y and Z co-ords.


Q15.6 : How do I generate a plot of the undeformed mesh with just the mesh outline?

Click on the Undeformed Shape Options.... and this will bring up Undeformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Basic tab if it is not already selected.
Click on Wireframe for Render Style. Then set the Visible Edges to
either Feature Edges or  Free edges . This draws the same mesh plot with only the outside edge.

------------------------------------------- factor. A value of 0.05 gives 5% shrink factor.
Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Other tab if it is not already selected.
Click on Shrink Elements for Scaling. Then set the factor. A value of 0.05 gives 5% shrink factor.
Click on the Undeformed Shape Options.... and this will bring up Undeformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Other tab if it is not already selected.
Click on Shrink Elements for Scaling. Then set the factor. A value of 0.05 gives 5% shrink factor.


Q15.7 : How do I get a plot of the deformed mesh only?

Click on the Deformed Mesh Plot icon, on the LHS.


Q15.8 : How do I get a plot of the mesh with node and element numbers?


lot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Labels tab.
Tick the boxes for labelling the nodes and the elements. Click on OK.
---------------------------------------
Click on Shrink Elements for Scaling. Then set the factor. A value of 0.05 gives 5% shrink factor.
Click on the Undeformed Shape Options.... and this will bring up Undeformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and ???


Q15.9 : How do I get only the node and element numbers for a subset of the mesh?

Use the Display Group option to display a subset you require if it is already been created.
Then Follow the procedure to label the whole mesh.


Q15.10 : How do I display the loading and boundary conditions?

Select the Load Module and then Load -> Manager


Q15.11 : How do I change the scale used for the displacement in plotting the deformed mesh?

Click on the Deformed Shape Options.... and this will bring up Deformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Shape tab if it is not already selected.
Set the Toggle switch to Deformed Shape.
There are 2 choices for specifying the scale factor for the displacement magnification. Under the heading Deformation Scale Factor if the toggle switch Auto-Compute is set the program calculates it by default.
The user can click on Uniform and enter a value in the box, to be used. Alternatively by clicking on Non uniform different scale factors for the different directions (X, Y and Z independently).

Q15.12 : What is the significance of the displacement magnitudes in a FREQUENCY analysis ie eigenmode analysis?

They have no special significance. The displacements in a mode shape are not absolute values. These ape not associated with any loading. These represent the shape distribution. Therefore instead of representing some arbitrary scale the shape is normalised.
The displacements are normalised to give the largest displacement or rotation to be unity.

Q15.13 : I have used the rebar option to model the reinforcement in concrete in an analysis. How do I display the position of the rebars?

Click on the Display group icon. Then select the element groups which represent the rebar elements. This is in general true fro displaying any sets of nodes and elements. Also true for any entity which is listed on the left hand side table.

Q15.14 : How do I mark the position of the nodes?

Click on the Undeformed Shape Options.... and this will bring up Undeformed Shape Plot Options form. This form has the following TABs : Basic, Color & Style, Labels, Shape, Limits and Other. Click on the Labels tab if it is not alreday selected.
Then Click on the following
 Show Node symbols 

Q15.15 : How do I create super-imposed plots of deformed and undeformed meshes?

Click on the following Super-imposed plot options icon and then click on the plot to be super-imposed.

Q15.16 : How do I prevent plots being super-imposed?

Click on the following Super-imposed plot options icon (to unset it) and then click on the icon for the required plot.

Q15.17: How can I produce a multiplot of the mode shapes of first 6 modes in a frequency analysis in a single figure?

The following python script can be used to produce the necessary figure. multi6.py (python script)

Q15.18: How can I produce a multiplot of the mode shapes of first 9 modes in a frequency analysis in a single figure?/

The following python script can be used to produce the necessary figure. multi9.py (python script)
