Import of VTK results format

GDAL library allow import raster images of GIS terrain models.

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.

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

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

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

Tetgen volume mesher (developed at WIAS Institute) inside GiD.

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

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

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.
