Resistivity inversion software (free to download)


ProfileR has been designed for surface array resistivity profile imaging. ProfileR is an inverse solution for a 2-D resistivity distribution based on computation of 3-D current flow using a quadrilateral finite element mesh. The inverse solution is based on a regularised objective function combined with weighted least squares (an 'Occams' type solution). The code supplied has been compiled for Intel compatable processors, users working on different platforms should contact the author.
 
ProfileR has no built in graphical interface. The user can use his/her own software for graphical output (e.g. Surfer). Alternatively the interface Zondres2D written by Alexander Kaminsky can be used. This is attached in the download bundle along with a readme file to explain how to get started. The plot shown here is an example of the output from the Zondres2D graphical interface written for ProfileR by Alexander Kaminsky
 

 
R2 is a forward/inverse solution for 3d or 2d current flow in a quadrilateral or triangular mesh. The inverse solution is based on a regularised objective function combined with weighted least squares (an ‘Occams’ type solution) as defined in Binley and Kemna (2005). Electrodes can be placed on the ground surface or in boreholes. A 32bit and 64bit version for Intel compatible processors are provided in the download.
 

 
R3t is a forward/inverse solution for 3D current flow in an unstructured (tetrahedral) or structured (triangular prism) mesh. The inverse solution is based on a regularised objective function combined with weighted least squares (an ‘Occams’ type solution) as defined in Binley and Kemna (2005). R3t runs in a 64bit Intel compatible processor (64bit is necessary for running large problems).
