CAPLET - fast-field electrostatic solvers scaled up by parallelizing

Looking for a new generation of fast-field solvers capable of being scaled up by parallelizing, recently I find the interesting project CAPLET on the same MIT site we can find FASCTAP.

Project CAPLET is a capacitance extraction toolkit that extract capacitance at field-solver accuracy. This is the open-source code under GNU Lesser General Public license aimed for ultra-fast extraction of small-to-medium structures with 5% accuracy of reference solutions and efficiently parallelized.Thought the author claimes the simplified installation procedure, it demands some steps. We did it on Ubuntu 10.04. You can use any virtual machine (VirtualBox, etc.), install Ubuntu 10.04, upgrade the OS and install the following package:


apt-get update; sudo apt-get upgrade
   apt-get install g++
   apt-get install libcr-dev mpich2 mpich2-doc
   apt-get install libblas3gf libblas-doc libblas-dev
   apt-get install liblapack3gf liblapack-doc liblapack-dev
   apt-get install gfortran
   apt-get install openmpi-bin openmpi-doc libopenmpi-dev

To compile QT GUI you can download, for example, Qt Creator 2.4.1 and Qt 4.7.0.

The toolkit has three solvers:

 1. Caplet (based on instantiable basis functions), 

 2. FastCap (additional link to the solver is required), and

 3. Standard BEM solver (piecewise constant basis functions with collocation testing, obviously without any acceleration).

We compared the standard BEM solver verus FASTCAP with -d0 option on the proven configuration (two parallel 100x2000x200 plates). The results are not the same :-0.
