Pre-release

3.4.0.3 (2024-03-28)

  • Updates for PDMY02 and CYCLIQCPSP
  • Added den to objects in consistent manner referring to mass density

3.2.0.7 (2022-12-13)

  • Allow saving results with a prefix for file names
  • Improved support for variable transient analysis
  • Improved mesh partitioning support for tied boundaries
  • Fixed issue with modelling imposed ground motions and multi supports

3.2.0.6 (2022-03-03)

  • Removed double underscore in parameter names
  • Added support for element Rayleigh damping

3.2.0.5 (2021-11-29)

  • Can now define algorithms and test checks without applying them, and can apply/reapply them to the OpenSeesInstance using the method .reapply()
  • Adding support for database commands
  • Minor changes to way inputs are handled for Hysteretic material
  • More support for Explicit solvers
  • Fixed issue with send command

3.2.0.3 (2021-07-15)

  • Added option to generate individual fibres
  • Added algorithms NewtonLineSearch and Broyden
  • Can now call get_node_coords using the node tag if kwarg node_as_tag=True
  • Fixed bug where parameters could not be passed to bcast
  • results now has support for parallel processors
  • Added missing parameters to algorithm.NewtonLineSearch object
  • Exposed openseespy as o3.ops to be consistent with the ops convention. o3.opy still available for backwards compatibility
  • Added ModalDamping
  • Added integrator.GimmeMCK to allow export for different matrices

3.2.0.2 (2021-05-24)

  • Fixed issue where the custom_openseespy package would not be used if installed. Now used as the default if available.
  • Can record node and element output to XML file using NodeToXML, NodesToXML, ElementToXML and ElementsToXML
  • Added uniaxial materials 'PySimple2', QzSimple2 and TzSimple2
  • Added support for Results2D output to handle manual node numbering.
  • Added method to results where node tags can be rezeroed if not using incremental node numbers
  • node.build_regular_node_mesh() can handle manual node numbers for 2D and 3D.
  • Added option for handling error when applying fixities to list of nodes (e.g. o3.Fix2DOFMulti) where node may be None.
  • New method on OpenSeesInstance, set_log_file() records logs to a temporary file.
  • Added option for system.apply_mumps_or(<alternative-solver>) where tries to apply MUMPS solver and if fails will apply an alternative solver.

3.2.0.1 (2021-01-28)

  • Updated gen_shallow_foundation_bnwf command to include shear elements
  • Added mp.partition command for automatically partitioning the model

3.2.0.0 (2021-01-10)

  • Removed reference to o3seespy in import statements within the package
  • Cleaned deprecated files

3.1.0.35 (2020-12-18)

  • Added support for 4 node elements
  • Fixed issues with using the ManzariDafalias material
  • Fixed issue with setting node mass when defining node, can now set with the mass=[<nodal-masses>] parameter

3.1.0.34 (2020-11-03)

  • Added support for parallel MP node numbering, can now set node tag on creation by passing tag=<tag-number>,
  • Added support for all OpenSees tags to support parallel MP numbering by having unique numbers for different processor ids, simply pass in mp=True into OpenSeesInstance().
  • Added o3.domain_change(osi) to provide the 'domainChange' command.
  • Added integrator.NewmarkExplicit

3.1.0.33 (2020-10-08)

  • Added senscmds (beta), `parallelcmds`(beta), `fsicmds`(beta)

  • Added commands for applying fixities to list of nodes (e.g. o3.Fix2DOFMulti), and for equal DOF command
  • Added function for generating a grid of nodes build_regular_node_mesh
  • Added option for compressing the output of an opy file by applying for loops for repetitive commands
  • Added add_fixity_to_dof to try to apply fixity but not fail if fixity already existing
  • Added friction_models containing all the friction model objects.
