Selva,
You may have a look at the Henry example which is very simplified, but based on the same principle. Let us know if you still encounter problems. Once you've installed the FEFLOW Demo Data package, you'll find the Henry benchmark in C:\Users\Public\Documents\WASY FEFLOW 6.2\demo\benchmarks\femdata\bench_henry.fem (path for Windows 7, can be different on other operating systems).
