PRO for OGS6

Hi all,

I have compiled OGS6 on at mac os Yosemite. I just found that OGS6 require pro file. I made a pro file:

<?xml version="1.0"?>
    <p algorithm="Serial" convergence="FemFunctionConvergenceCheck" max_itr="1" epsilon="1e-4">

            <out>PRESSURE</out>

            <out>VELOCITY</out>

            <problems>

            <M name="cae" type="RICHARDS_FLOW">

            </M>

            </problems>

    </p>

And when I run the OGS6, I got error:

./ogs cae.pro

debug: Project configuration from file ‘cae.pro’ read.

libc++abi.dylib: terminating with uncaught exception of type boost::exception_detail::clone_impl<boost::exception_detail::error_info_injectorboost::property_tree::ptree_bad_path >: No such node (OpenGeoSysProject)

Abort trap: 6

I will appreciate if anyone can provide a .pro example for me.

Thanks,

Xuan
