pbeam's Introduction

pBEAM

A finite element method for beam-like structures.

Author: NREL WISDEM Team

Documentation

See local documentation in the docs-directory or access the online version at http://wisdem.github.io/pBEAM/

Prerequisites

C++ compiler (with c++11 support), NumPy

Note that any modern compiler (gcc, clang, etc) on Linux or MacOS will support the c++11 standard. On Windows, recommend to use mingw through Anaconda or gcc on Cygwin.

Installation

For detailed installation instructions of WISDEM modules see https://github.com/WISDEM/WISDEM or to install pBEAM by itself do:

$ python setup.py install

To check if installation was successful run Python from the command line

$ python

and import the module. If no errors are issued, then the installation was successful.

>>> import _pBEAM

Unit Tests

pBEAM has a large range of unit tests, but they are only accessible through C++. They are intended to test the integrity of the underying code for development purposes, rather than the python interface. However, if you want to run the tests then change directory to src and run

$ make CXX=g++

where the name of your C++ compiler should be inserted in the place of g++. The script will build the test executable and run all tests. The phrase "No errors detected" signifies that all the tests passed. You can remove the remove the test executable and all object files by running

$ make clean

Missing libraries for compilation on Ubuntu 14.04

Hi,

I am trying to compile the pBEAM on my Ubuntu 14.04 machine using the makefile scripts. The compilation of the src/pBEAM files works fine. However, there are some issues with the makefile for src/pyBEAM. I modified the makefile script as follows. Still I have the attached error from the compiler.

Do you have any idea which libraries are still missing? It seems to be a python related lib.

Regards,
Malo

src/pyBEAM/makefile:

CXX = clang++
CFLAGS = -O2
PY_FRAMEWORK = /usr/include/python2.7 # /usr/lib/python2.7
BOOST_INCL = /usr/include
BOOST_LIB = /usr/lib/x86_64-linux-gnu
INCL = -I$(BOOST_INCL) -I$(PY_FRAMEWORK) -I../pBEAM
LIB = $(BOOST_LIB)/libboost_python.a $(BOOST_LIB)/libboost_system.a $(BOOST_LIB)/libpython2.7.a -lpthread -lz -ldl -lutil #some python lib?
OBJ = ../pBEAM/Poly.o ../pBEAM/myMath.o ../pBEAM/BeamFEA.o ../pBEAM/Beam.o

Fortran Equivalent

Is there a Fortran equivalent of pBEAM or any other 3D beam model for turbine blades available for academic purposes (i.e. free)? You mention it's based on the book by Yang 1986, but doesn't that book already include Fortran code at the back? I want to implement pBEAM on a cluster, but all the prerequisites make it difficult to do so. I want to combine pBEAM with PreComp into a single executable.

I'm trying to get a copy of that book, but it's old and I can't download it from the internet.
