NORSAR-3D FAQ

This could be caused by a local Python installation on your computer. Please check if you have a PYTHONHOME environment variable set on your system and remove it before running NORSAR Software Suite.

When starting a module, a printfile containing log information, will automatically be created in a folder called .pf. If this is not possible, the error message is given. The .pf directory is located at the same level as the Home Directory in the select project dialog or in the environment variable SM_HOME. Check the access codes and the ownership of the .pf directory and set it readable and writeable for your user.

• The read/write access of the .pf directory does not allow you to open a printfile. When starting a module, a printfile containing log information, will automatically be created. If this is not possible, the module willl exit. The .pf directory is situated at the same level as the Project Directory. Check the access codes and the ownership of the .pf directory and set it readable and writeable to your user.

• The X-server on your display-host may not authorize access from the remote host on which you are running the software. The reasons may be:
  • Max number of X-clients are connected to your X-server. Exit some of the X-applications that are running.
  • Client is not authorized to connect to server. Authorize the client with xhost +<remote host>

The restart files for NORSAR-2D and NORSAR-3D containing the project directory paths can be found in the following files:

$HOME/.n2d/*, $HOME/.n3d/* and $HOME/.N23DProjectHomes.restart

These files can be edited or removed without losing any data.

The conversion consists of two steps:

1. In NORSAR-2D, store the NORSAR-2D model on the Seismic Model Interchange File (.Smif) ASCII format.
2. In NORSAR-3D, load the .Smif file and make a NORSAR-3D model.

There are two different ways to do this conversion:

• Method 1

You can always use this procedure, but it may in some cases change the global coordinates of the model. NORSAR-2D and NORSAR-3D may use different projects.
 

• Method 2

can only be used if the NORSAR-2D modeling Section is an Inline or Crossline section in the NORSAR-3D project. NORSAR-2D and NORSAR-3D must use the same project. The coordinates are retained.

Method 1

1. From the NORSAR-2D Console Window select File > Export > SMIF Generator.
2. Set a suitable output directory.
3. Generate the .Smif model. It is stored as an ASCII file on the selected directory.
4. From the NORSAR-3D Console Window select File > Import > Model Import > N2D Smif import.
5. Set directory, select the .Smif file, and Convert.
6. A cylindrical, 2.5D NORSAR-3D model is made. The 2D model varies in the x-direction in the model coordinate system. The model is invariant in the y-direction.

Method 2

1. From the  NORSAR-2D Console Window select File > Export > SMIF Generator.
2. Use the default output directory ‘./’.
3. Generate the .Smif model. It is stored as an ASCII file on the selected directory.
4. From the NORSAR-3D Console Window start Functions > Model > Model Builder.
5. In the Model Builder, select File > Load > 2D model from Smif. Select the section-model combination and load. 
6. In the Model Builder, select 2DModels > 2.5D model from 2D. Select the section-model combination and make the 2.5D model.
7. Select the model in the hierarchy window and in File > Store > Selected group/model as… store it ‘As model ready for ray-tracing’.

Due to an issue in Motif, files larger than 2 GB may not show up in some file dialogs. Please type in the file name manually.
