6.3.11 Using the fe2ram Filter to Convert Files

The fe2ram filter can be used to manually convert files of certain formats into ANSYS FLUENT mesh files, which can then be read into ANSYS FLUENT. To use the fe2ram filter, enter the following at a command prompt in a terminal or command window:

utility fe2ram [ dimension] format [ zoning] input_file output_file

Note:   The items enclosed in square brackets are optional. Do not type the square brackets.

• dimension indicates the dimension of the dataset. Replace dimension with -d2 to indicate that the mesh is two dimensional. For a 3D mesh, do not enter any value for dimension, because 3D is the default.

• format indicates the format of the file you wish to convert. For example, replace format with -tANSYS for a Mechanical APDL file, -tIDEAS for an I-deas file, -tNASTRAN for a NASTRAN file, etc. To print a list of the formats which fe2ram can convert, type utility fe2ram -cl -help.

• zoning indicates how zones were identified in the original format. Replace zoning by -zID for a mesh that was zoned by property IDs, or -zNONE to ignore all zone groupings. For a mesh zoned by group, do not enter anything for zoning, because zoning by groups is the default.

• input_file is the name of the original file. output_file is the name of the file to which you want to write the converted mesh information.

  For example, if you wanted to convert the 2D I-deas volume mesh file sample.unv to an output file called sample.grd, you will enter the following command:

  utility fe2ram -d2 -tIDEAS sample.unv sample.grd
