phs-poly 0.2.3

PHS+poly approximation procedures

phs_poly

Procedures for generating RBF-FD weights for derivative calculations.
Currently only PHS + poly approximations in 2-d are supported.

---

Installation

To install use,

pip install phs_poly

Requirements_

• A Fortran compiler (e.g. gfortran or flang)
• A LAPACK library (e.g. OpenBLAS, Accelerate, ArmPL)
• NumPy

Quickstart

import phs_poly

# ... set x- and y-coordinates, initialize work and coeff arrays ...

ierr = phs_poly.phs3_poly2(n,x,y,coeffs,ldc,wrk,iwrk)

# First derivatives weights
wx = coeffs[0:n,0] 
wy = coeffs[0:n,1]

# Second derivative weights
wxx = coeffs[0:n,2] 
wxy = coeffs[0:n,3]
wyy = coeffs[0:n,4]

Features

• RBF-FD weights for derivative operators
• PHS + poly based approximation
• Designed for 2-d problems
