How to create child layers

A geometric representation is composed of four types of entities, namely points, lines, surfaces, and volumes.

A layer is a grouping of entities. Defining layers in computer-aided design allows us to work collectively with all the entities in one layer.

You can create a layer inside another one, this new layer is called “child” layer.

You can do it from Layers and groups window in preprocess mode. Just go to Utilities->Layers and groups

Create childs selecting the parent and:

  • clicking the “create child”¬†button
  • right-click and select New child

Join volumes

It’s possible to merge volumes without losing attached data.

With this option two or more volumes connected by shared surfaces are joined in a single one. That option avoids deleting manually the shared surfaces and selecting the new boundary.

join_volumes

Go to Geometry->Edit->Join->Volumes in the top menu and select all the volumes that you want to join.

How to rebuild the internal information of a surface

Sometimes some surfaces are not well defined and we need it to clean them, this is only one click away with the Rebuild surface by boundary option.

You can find this option in preprocess mode going to top menu Geometry->Edit->Rebuild surface by boundary

After selecting some surfaces, each surface will be remplaced by a NURBS surface created by the boundary information.

 

Change theme

Try a GiD different look.

User can choose between Classic and Black themes, which change drastically the GUI appearance.

Open the Preferences window and go to Graphical->Appearance branch. There go to GiD Theme->Theme and select the desired theme. Click on Apply button to confirm.

You will be asked to restart GiD, click Yes andGiD will start with the new selected theme.

Parallel meshing

GiD runs in parallel (shared memory) when meshing unstructured and structured volumes.

Number of threads to use can be set in the preferences window. Just go from the top menu to Utilities->Preferences, select the  General->Other branch and modify the Number of threads to use option.

How to trace nodes

The node tracing option in GiD allows the user to track nodes, whose traces are displayed. For a single mesh for the whole analysis, the node will follow the path of the deformed mesh across all steps. When several meshes are used for several time steps, then the nodes can follow the track of the original mesh or from the deformed one.

Select View results->Node trace in the postprocess top menu in order to activate this visualization option.

How to get the numerical values of a graph

When you create a graph from GiD it’s possible to view¬†the numerical values in a¬†table.

To access to the table just open the Graphs window from top menu (Window->View graphs…) and go to the Options tab. There you can select the graph and click on Show table button.

A table with the values of the graph will be shown. This table is interactive which means that the values can be updated. Just select a cell, change the value, click in Apply button and the graph will be updated. You can check the changes in the Plot graph tab of the window.

You can also add or remove rows in the table using the arrows buttons.

The values can also be copied and pasted in a spreadsheet software, for example.  You only have to select them, press Ctrl-C and they will be copied to the clipboard.

Check for updates

You can check if your GiD version it’s up to date from the top menu.

Just select Help->Check for updates…

Please notice that an internet connection it’s needed.

Reload last model

Option available to reload automatically last model used when opening GiD.

This option can be activated in the preferences window. Just go from the top menu to Utilities->Preferences, select the  General->Other branch and check the Reload last model option.
