FRANC2D, CASCA and Translators FRANC2D is a two dimensional, finite element based program for simulating curvilinear crack propagation in planar (plane stress, plane strain, and axisymmetric) structures. CASCA is a simple pre-processor for FRANC2D. Other 2D finite element programs can be used as a pre-processor for FRANC2D provided the data can be converted to FRANC2D input. We have some translators available that will convert commercial 2D finite element data to FRANC2D input.
FRANC2D Versions 3.1 and beyond are capable of reading in .inp files with more than 9999 nodes. Note that if you run the MS Windows version, you can run from the CMD shell with the -mem flag to allocate additional memory, i.e. "c:/franc/f2d.exe -mem 100000000". The FRANC2D Primer is both a tutorial and menu reference.

Translators from ansys (.cdb) to franc2d (.inp) for MS Windows and RedHat Linux 8.0 are available in executable form. These should work for ANSYS 6.1 files. Note that franc2d expects only one region. If the resulting .inp file fails to read into franc2d, try editing the file and remove the loading and fixity information at the end of the file. Other translators for several different FEM packages are available below to allow one to convert FEM input into FRANC2D input. The source code is provided. You must compile the source yourself before running. Read through the comments at the top of the source code for some help. Otherwise, just use cc or f77 to compile the code (no other libraries or source is required). The castofranc translator has been updated and a MSWindowsXP executable is provided below as well as the C source code. This version should work with the Cornell version of Casca and Franc2d/L - it will likely not work with the Kansas State version because of the difference in format in the .inp files. We now use a free format for the element node listing while the old version was restricted to field widths of 5.
