        RWCap-v3: floating Random Walk based Capacitance solver for conductor structures. Version 3 released. [2016]
        Contributors: Zhezhao Xu, Bolong Zhang, Chao Zhang. Supervisor: Wenjian Yu.
1. The package includes two programs: "rwcap-solver" and "TechGFT". They are for performing 3-D capacitance extraction, and preparing the GFT/WVT data for the rwcap-solver, respectively. Their paths are "rwcap-solver/rwcap" and "TechGFT/TechGFT", respectively.
2. Deferent from previous versions, TechGFT is now a standalone program not relying on Matlab.
3. The package also includes a lot of test cases in our publications. For the syntax of case file, please refer to the documents in RWCap-v2 website. Notice that term "qbem" is always exchangeable to term "cap3d".
4. For the usage of the programs, please refer to the documents in RWCap-v2 website. Also, please carefully read the "readme.1st" file in the package.
5. The programs have been tested on 32-bit and 64-bit Redhat and Ubuntu Linux systems. TechGFT may be unstable on older systems. Please try to run them on newer system with Linux version 3, and glibc with version > 4.

Two running modes of the rwcap-solver:
$ ./rwcap --gft <data_dir>
Register the folder "data_dir" storing the data generated by TechGFT.
$ ./rwcap -f <file_name>
-p <err_self_cap> | -c <err_coup_cap> | <Other_control>
[-n <num_thread> ] [-o <output_file> ] [other_options]
"-f" specifies the input file name.
"-p/c" specifies the threshold of relative error of Self/coupling capacitance.
"-n" specifies the number of threads for parallel computing.

For the algorithms implemented in this software and test cases, please refer to the following papers.
