Description:

opswrapper 5.2.0

Python wrappers and helpers for (Tcl) OpenSees analyses.

Installation
Conda:
conda install -c otaithleigh opswrapper

Usage
The objects provided in this package largely line up with their OpenSees Tcl
counterparts. The general workflow is to create a list of objects, and then call
str on them while printing to a file. Each entry in the list will become a
line in the Tcl script, allowing for mixing of raw Tcl code and opswrapper
objects.

Simple Example
import opswrapper as ops
model = []
model.append(ops.Model(ndm=2, ndf=3))
model.append(ops.Node(1, 0, 0))
model.append(ops.Node(2, 0, 10))
model.append(ops.material.Elastic(1, 29000))
model.append(ops.element.Truss(1, 1, 2, mat=1, A=10))
print(*model, sep='\n')
Output:
model basic -ndm 2 -ndf 3
node 1 0 0
node 2 0 10
uniaxialMaterial Elastic 1 29000
element truss 1 1 2 10 1

Formatting
Objects can be formatted via multiple ways. The simplest is to convert them to
str:
>>> str(Elastic(1, 29000.))
'uniaxialMaterial 1 29000'
A float format specifier may be specified when used with the built-in format
commands:
>>> format(Elastic(1, 29000.), 'e')
'uniaxialMaterial 1 2.900000e+4'
>>> f'{Elastic(1, 29000.):.2e}'
'uniaxialMaterial 1 2.90e+04'
Specifiers for other types may be passed using the tcl_code method:
>>> Elastic(1, 29000.).tcl_code({int: '4d'})
'uniaxialMaterial Elastic 1 29000'
Defaults can be set on a global basis using base.set_global_format_spec, on a
per-class basis using cls.set_class_format_spec, or on a per-object basis
using self.set_format_spec:
>>> set_global_format_spec({float: '#.3g'})
>>> section.Elastic2D.set_class_format_spec({float: '#.3g'})
>>> s = section.Elastic2D(...)
>>> s.set_format_spec({float: '#.3g'})
Each of these methods return the previously-set modifiers if you wish to restore
them later.
